I've started the planning stage of a game I'm writing. It is a tile based network game. The game will run at full screen (form.width = screen.width etc) and the graphics will be BitBlted onto the form.

What I am worried about is the speed that this will run at. There will be projectiles and since it's multiplayer there'll be multiple units on the screen plus the tiles. From experience, will this kind of setup run too slow with VB on a fairly (sub) standard PC? This is quite important, since if the game cannot run at decent speeds, there would be no point in me continuing the project.

Thanks for all input.
