Hi it appears non of my sprites (i think) are working, when I run spacewar, in which I have to disable multisampling, the ships, and the "star" are black. The flames for the ships are coloured, and I believe the explosions work.

That suggests to me a problem with the shaders. Though the backdrop animation also goes through a shader so not sure why that is appearing.
Actually the sprites are working fine - she ship engines and particicles and the HUD elements are all sprites. Its all the non sprite stuff thats not working.
What is your graphics card?
Have you ever used PIX? That might be the only way to debug this.
GForce 4200 is a DX8 card that support Shader Model 1.3. You are lucky it runs at all.
I suspect the background shader is simple enough that it works in 1.3 but the ship and sun shaders are too complex. I would have hoped for an error somewhere so you should report this as a bug on connect.microsoft.com
And I have question about multitasking. Why I always must switch it on? Why this happends?
