P4 Glitch?

[made_of_asp]

Hi,

I recently ran "Please the Cookie Thing" demo on two school computers, where one is a PIII 800 Mhz with Win98 and 64Mb RAM and the other P4 1.7 Ghz with WinXP and 256 Mb RAM.

Suprisingly, the demo runs smooth on the older system, but on the new system it runs with frequent stops (every 1 second).

My AMD Athlon 2000 system handles the demo very well.

What is this? Glitch? Affected by Win XP? The demo uses OpenGL.

Thanks for your help,

Probably just something to do with the software setups on the P4 system. I doubt its hardware.

Yeah I would imagine that there's something running on the WinXP machine that's sucking up CPU time.
Try going into task manager and then into processes to see what's running.

Also, the video drivers for the winxp machine might be quite old and not support opengl very well ?

I'd say the software doesn't like DirectX 8.1 very much. Your Win98 system is probably running 6.0 or 7.0.

I'de agree with both previous posts though... Any problems like that would be picked up from a simple GL / D3D test, so the hardware is probably fine.

Regards,

Paul.
