[2008] Graphics Test. Looking for results from Vista users. Use Post # 39 attachment.

[EntityX]

I recently upgraded to Vista Business from XP Home. I found that my Visual Basic 2008 graphics applications is running much much slower in Vista than it was in XP. I took a small piece of my application and created a test program. I've set my computer up for dual boot so I now have XP Home and Vista Business on it. I've run my test program from both OSs and the results are tremendously different.

I have a custom built computer that has a Microstar Int. KT6 - V mother board. It has an AMD Athlon XP 3200 + 2.2 GHz with 2 GB RAM. It's a 32 bit processor. I do have the 32 bit version of Vista installed. I have only PCI slots and one AGP slot on my mainboard. I'm using a NVIDIA GeForce2 Graphics card that I bought back in 2005 with 32 MB RAM. My Vista Experience Index subscores are as follows:
Processor : Calculations per second - subscore 3.6
Memory(RAM) : Memory operations per second - subscore 4.2
Graphics : Desktop performance for Windows Aero - subscore 1.9
Gaming Graphics: 3D business & gaming graphics performance - subscore 1.0
Primary hard disk : disk data transfer rate - subscore 5.3

The test program that I created runs 3 screens that are the same except for the pen thickness. Screen 1 uses a pen thickness of 1. Screen 2 uses a pen thickness of 2 and screen 3 uses a pen thickness of 8. When I run the Graphics Test program my results from XP Home on my computer are as follows.
Screen 1 duration = 7,781 milliseconds or 7.781 seconds
Screen 2 duration = 7,796 milliseconds or 7.796 seconds
Screen 3 duration = 7,796 milliseconds or 7.796 seconds

All pretty much the same.

From Vista Business my results are as follows:
Screen 1 duration = 119,062 milliseconds or 119 seconds - Pen Thickness = 1
Screen 2 duration = 20,234 milliseconds or 20.23 seconds - Pen thickness = 2
Screen 3 duration = 21,609 milliseconds or 21.6 seconds = Pen thickness = 8

Usually when the pen thickness is lower the drawing is quicker but my Vista results show something very unusual happening. When the pen thickness is 1 the drawing is 6 times slower than when it is 2. The drawing is about 15 times slower in Vista than in XP when the pen thickness is 1.

I'm going to attach the program I created and someone can let me know if they were able to install it and run it from the attachment. If you run it let me know your results if you run it from Vista and let me know your computer set up. What's all the goods on your computer. What kind of graphics card do you have. Is it PCIexpress, PCI or AGP.

Next post will have attachment.

Are you running Aero Glass? With such a low Graphics score that could be a problem. Try turning down the visual effects in the OS and see if that makes a difference. If it does then you can assume that anyone running Vista on reasonably recent graphics hardware should have no issue.

[EntityX]

Remeber I'm looking for Vista users. If you have XP and you want to run it and give me the results that's ok but I'm primarily looking for Vista users. After you install the Graphics Test program it won't place an icon on the desktop for you but if you look in programs it should be there as Graphics Test. Go to post # 39 for attachment.

Aero Glass is off. I tried adjusting the visual effects before and no improvement. I tried it again and still no improvement. I went to the visual effects screen and clicked adjust for best performance. I ran another test and there was zero improvement. I tried putting an ATI Radeon HD 2400 PRO AGP graphics card in my computer and the subscore for Graphics went from 1.9 down to 1.0. There's a whole other story on trying the ATI card.

When I get the money I'll upgrade my computer but in the mean time I'm wondering how my application will run on computers that are more capable than my own.

[EntityX]

I tried downloading and installing from the attachment but it doesn't work. I've created a setup program that will install Test Graphics fine but when I zip it something gets left out.

[EntityX]

Here's another attachment. I just tested it and was able to download, unzip and install successfully. Graphics Test will be in list of programs after installation.

[EntityX]

If you run the program and give me the results let me know the essentials on your computer as I said before and if you could also give me the Windows Experience Index Score and subscores. Start > Welcome Center > Show More Details (top right of screen) > click Performance in lower left and then you'll have the screen that gives you the Windows Experience Index and the subscores for different areas of performance. If nothing else give me the Graphics subscore and Gaming Graphics subscore.

I'm sorry but I had to remove the attachemnts as they were executables. Its against the Forums olicy to allow them. Please upload your source code so members can compile their own versions for testing for you.

You can not compare XP environments against Vista. Vista uses alot more memory and DirectX. Its like comparing Apples to Oranges.

[EntityX]

Didn't know about that policy but now I do. I seriously doubt anyone would be interested in doing the work to put it all together that's why I created an install program but if no one does that's ok. If I don't get any feedback it's no big deal. Go to Post # 39 for attachments for Graphics Test.

[RobDog888]

I dont doubt that your app is safe but we have to apply the rules fairly to all. Its basically to help protect members from compiles that may be harmful to their systems since there is no source code they have no way to know if its safe. Now that you have uploaded your source I'm sure you actually may get more testers participating.

[EntityX]

What if I were to provide a link to where they could download my app. Would that be ok? If they don't want to take the risk of downloading it they don't have to.

[RobDog888]

Nope, its the same thing and could get into "advertising" areas. Sorry

[EntityX]

That's ok but it seems that I've seen many times on VBForums that people put up links for downloading of programs but maybe that was ok because they weren't programs written by VBForums memebers.

I've rewritten my program some so it would be easier to recreate.

I just found out about the 10000 character limit for a post because I exceeded it and then brought it down. Above post is very close to limit now. I eliminated 3 modules by making 3 functions associated with the main form. The chances that someone will take the trouble to recreate this should go up but if no one does that's ok. I'll say it looks cool visually and you can alter the value VisualVarietyFactor from 0 to 9 to get different effects and you can also play around with GraphicsPen to get different colors. I'm principally interested in getting the test results but maybe I can lure someone into taking the trouble to run it by telling them that it looks really cool to run and it does. After you get the results you could alter it for your own pleasure. Label2 needs to be big. Shouldn't be autosize.

A Vista Experience score of 1.0 is probably your problem, particularly as the lowest score is Graphics

[RobDog888]

@EntityX, you do know you can zip the project source files up and attach it to a post instead of just the files?

[EntityX]

See Post # 39 for Graphics Test attachment.

[.paul.]

OK. Here's all the source files and the project file in one zip. If you have Visual Basic 2008 installed on your computer then just unzip the attachment.
If you're looking at the unzipped files you'll see :
Form1.Designer.vb
Form1.vb
Graphics Test
Variables.vb

Double click Graphics Test. That's the Visual Basic Project file. A solution should be created and Visual Basic should open. You can then run the program.

it doesn't run. you've removed too many files. zip it again + repost

[.paul.]

ok. i've run it. interesting graphics. it runs well on my PC (vista x64 home premium, on amd phenom 8.8ghz quad core with 1gb graphics card. windows experience score = 4.8).
do you want me to time it? how?

[.paul.]

screen 1 duration = 57842.9775 milliseconds
screen 2 duration = 9627.3135 milliseconds
screen 3 duration = 10540.341 milliseconds

With a quad core and all that power its still only a 4.8?
I have a dual core and average memory and I get a 5.5 minimum index score

I'll test the code when I get home tonight.

Thanks very much .paul. I appreciate the results. You have very serious power on your computer yet my XP screen durations are lower. When the pen thickness is 1 the screen duration is still about 6 times slower in comparison to when the pen thickness is 2 just like on my computer when Vista is being used.

From XP Home on my computer:
Screen 1 duration = 7,781 milliseconds or 7.781 seconds - Pen Thickness = 1
Screen 2 duration = 7,796 milliseconds or 7.796 seconds - Pen thickness = 2
Screen 3 duration = 7,796 milliseconds or 7.796 seconds - Pen thickness = 8

From Vista Business on my wimp computer results are as follows:
Screen 1 duration = 119,062 milliseconds or 119 seconds - Pen Thickness = 1
Screen 2 duration = 20,234 milliseconds or 20.23 seconds - Pen thickness = 2
Screen 3 duration = 21,609 milliseconds or 21.6 seconds - Pen thickness = 8

From Vista x64 Home Premium on .paul's super power PC
screen 1 duration = 57842 milliseconds or 57.84 seconds - Pen Thickness = 1
screen 2 duration = 9627 milliseconds or 9.627 seconds - Pen thickness = 2
screen 3 duration = 10540 milliseconds or 10.54 seconds - Pen thickness = 8

It's pretty close to a 2 : 1 ratio between our computers as far as durations go for running the screens when comparing results from Vista.

There may be some kind of glitch in Visual Basic 2008 in it's compatibility with Vista or some glitch in Vista in it's use of the .NET Framework 3.5 and Visual Basic 2008 that creates the unusually slow drawing when the pen thickness is set to 1.

.paul I'm giving you a positive rating for your post. Anyone who runs my test program from Vista and gives me the results I'll give a positive rating at this time up to 10 different results from 10 different members. That should be enough.

.paul was there something that you did to eliminate the original problem you had after unzipping.

If you look at the comments in the code it will tell you how to get some variations in the visual effect. You can alter the value of VisualVarietyFactor. It's set to 0 but you can set it to any value 0 to 9 to get different results. Look at second line down under where you see Sub Timer1_Tick. After you run the test and get the results you could set the pen thickness to 2 which will give you 6 times better speed from the first screen. You can play around with the values for GraphicsPen to get different results for colors.

Code snippet from line 76 of Form1.vb

GraphicsPen = New Pen(Color.FromArgb(SelectValue3(IC * 2, 255), 160 - SelectValue3(IC * 2, 150), SelectValue(IC * 2, 50) * 4), PenThickness)

The RGB color component values shouldn't go above 255 so for the functions SelectValue, SelectValue2 and SelectValue3 the second value inside the parentheses should be 255 or less unless your playing around with the result some how. You could replace PenThickness(see above code snippet and scroll right) with 2 and delete label4 if you already have the test results and just want to play around with the graphics.

Also if you run the test and get the screen durations could you also give me the subscores for Graphics and Gaming Graphics. See post #7. It tells you how to get to the screen that gives you the Windows Experience Index score and subscores for the different types of performance.

]I didnt read the entire thread but are you comparing times when tested in the compiled exe state or in the IDE as source code?

[.paul.]

[color=navy]With a quad core and all that power its still only a 4.8?
I have a dual core and average memory and I get a 5.5 minimum index score

yeah well it would be off the scale but the 1gb graphics lets it down

[EntityX]

I've run the test both ways. When using XP there's just about zero difference in the test which was surprising to me. When I used Vista and compared the times running from IDE or from the program installed and running outside Visual Studio the numbers were very close. IDE numbers were just slightly slower, that is screen durations were just slightly longer.

[EntityX]

I just did another comparison. These are results from Vista Business only.

Screen 1 duration from IDE = 117,703 milliseconds or 117.703 seconds
Screen 1 duration from installation = 117,390 milliseconds or 117.39 seconds

Screen 2 duration from IDE = 20,109 milliseconds or 20.109 seconds
Screen 2 duration from installation = 20,062 milliseconds or 20.062 seconds

Screen 3 duration from IDE = 21,656 milliseconds or 21.656 seconds
Screen 3 duration from installation = 22,281 milliseconds or 22.281 seconds


I tried it again and got similar results. Note how the screen 3 duration is higher from the installation but when I did the tests again the screen 3 durations were the same from IDE and installation.

[EntityX]

In the above testing Visual Basic 2008 was targeting .NET Framework 3.5. I was wondering if I targeted .NET Framework 3.0 or 2.0, would it make a difference. It didn't. I tried both 3.0 and 2.0 from IDE and 2.0 from installation and all the results pretty much stayed the same. You still see the times about 6 times slower when the pen thickness is 1 in comparison to when the pen thickness is 2. Microsoft still has some debugging to do of something. Vista probably since the problem doesn't exist when you run Graphics Test from XP.

[RobDog888]

I was gonna try it for you but its missing the resx and other files so I cant rebuild the exe. Sorry but I want to do a fresh compile of the exe.

[EntityX]

Don't worry about it. I reported the problem as a bug at the Microsoft Connect site and just got an email that said that they were able to reproduce the problem I reported. I sent them a zip attachment of the installation program for Graphics Test.

We were able to reproduce the issue you are seeing. We are escalating this bug to the product unit who works on that specific feature area. The product team will review this issue and make a decision on whether they will fix it or not for the next release

The one result I got from .paul.'s computer is really good enough. He has enormous power on that computer. I didn't even know they had 8.8 GHz computers out there. And now I have confirmation from Microsoft Connect too.

[Andicioz]

Hi, I've got some interesting results for you (at least I think they are.)
They are somewhat near your XP results.

These are my computer specifications:
Asus P5K (Intel) Motherboard
Intel Quad Core Q6700 @ 2.66GHz
4GB DDR2 RAM
Asus/nVidia GeForce 8800GTS 512MB
Windows Vista Ultimate 32 with Aero fully enabled.
Index Score: 5,8
Screen 1 Duration: 28082ms (it is weird that this takes so long!)
Screen 2 Duration: 7790ms
Screen 3 Duration: 7781ms

So it's only the first that takes longer.
By the way, I've never heard of a quad core processor with 8.8Ghz o_O must be giant overclocking or either it might be a 2.2Ghz. It's just a slight difference :P

[obi1kenobi]

With a quad core and all that power its still only a 4.8?
I have a dual core and average memory and I get a 5.5 minimum index score

I'll test the code when I get home tonight.

Well the problem with the scores is that they only state the minimum score. So he may have 4 scores in the 5+ region (e.g. CPU, HDD and the two graphics scores) but score only 4.8 in the memory (a friend of mine has x64 Vista with 1GB of memory and his memory score is 4.3, says that x64 requires about twice as much memory as x86).

The one result I got from .paul.'s computer is really good enough. He has enormous power on that computer. I didn't even know they had 8.8 GHz computers out there. And now I have confirmation from Microsoft Connect too.

Actually, there are no commercially available 8.8 GHz CPUs. Last time I checked, the highest clock speeds were in the 5 GHz region. I believe that what .paul. meant was that he has quad core (4 processors) at 2.2 GHz each.

Btw, I also couldn't do a fresh compile of the exe, and I'd really like to see the results. I'm running Win Vista Business, dual core 2.4 GHz, 2 GB RAM. Could you pls upload the entire project, along with the .resx files and everything?

[EntityX]

Thanks for the extra results. I've got to run now but later today I'll post again with a better attachment that has all the goods for my Graphics Test app since I see that there is some interest in it. You could start a fresh project and copy and paste from above post. Place 4 labels. Timer1 should be enabled and interval = 10.

[Andicioz]

Actually, if you download the attachments from #13, and place them in a project, it works excellent.

Now, I've done some additional testing for you: I added some logging code to the project: It logs the time needed to perform each drawing action. I ran it:

I've attached the file. It is kind of big (80kb :P) as it logged the values for each screen.

You can notice that from certain IC's the time required is increased at the first screen. I dont know if it is much use to you though, but it didnt take much time so I just did it.

(System specifications are in previous post)

[RobDog888]

@EntityX, Thanks. I know we can run the included exe but for safty and following the Forums rules it really shouldnt have been included.

[EntityX]

RobDog are you referring to Andicioz's post just before your last post. I haven't posted any executables on this site since you told me about the policy.

Andicioz thanks for your work. I ran your test. It illustrates clearly how the frame rate changes during different portions of screen 1. When the drawing area diameter is small the frames run by rather quickly but when the drawing area diameter goes up the frame rate(IC for Image Count) slows way down. On my computer when using Vista certain portions of screen 1 will run at only around 1 frame per second. Andicioz you should know that RobDog(and probably any other VBForums moderator) doesn't want us posting executables. I did myself before and they were unposted.

I'm attaching a zip of the VB files. No executables. If you have Visual Basic 2008 on your computer unzip and click on Graphics Test solution or Graphics Test project file(inside folder Graphics Test) and Visual Basic should open and you should be able to run it. Go to Post # 39 for attachment.

I said before that anyone who runs the test and gives me the results I'd give their post a positive rate. I withdraw that statment now because I have all the results I need. So only run it if you want to run it. I might give your post a positive rating if I feel you've contributed something worthwhile but no promises. Here and there when I'm really helped out I do rate the posts.

If you run the test and have some results that are significantly different from what you've seen so far then that would be a reason to post the results. Screen 1 is very slow. Screens 2 and 3 are a lot faster. This is what everyone is seeing in Vista.

[EntityX]

Andicioz I see you just attached a text file. So I'm not sure what RobDog is referring to.

[EntityX]

To add a note, in case anyone is wondering if the just released Visual Basic 2008 with SP1 makes any difference in the test, it doesn't. I've already installed it and tested and no difference. I installed Visual Basic 2008 Express with SP1. I doubt the Standard version with SP1 would make any difference but if someone finds that it does they can let us know. Microsoft Connect team would have tried it and told me I would think. See post # 30.

[EntityX]

The attachment in Post # 36 has executables in the bin and obj folders but I didn't know about them when I made the attachment. It was an unintentional post of executables.

Here's an attachment that has no executables. After you double click the Graphics Test project file inside folder Graphics Test the obj and bin folders will be created and they will have executables in them then so it doesn't make that much difference but I can say that this zip file doesn't have any exe files in it as far as I am aware.
