Gamma Ramp doesn''t work with older video card.
I second NitroSR''s suggestion, use Alpha Blending - It looks good and runs very fast.
There''s an article about it at Mr GameMaker.

The alpha blending method in Mr Gamamakers tutorial, it is emulated by DX if no 3DFX card is present isn''t it?

n0p3x: In the tutorial, they first try to create a TnL device (Transformation and Lightning - I think) which is supported by the latest GeForce chipset.
Then, if it doesn't succeed they try to create an HAL device (It's hardware accelerated) which is suppported by all of the video cards (Including 3Dfx's cards).
Then if that doesn't succeed they try an MMX software device - It's the same as a normal software device only a little faster using MMX commands.
And If that doesn't succeed an RGB device is created - software emulation. Really slow, but works.
In other words: Yup

soehrimnir: Look in the DX SDK, their might be some useful info for you there.
