I just I would show you this (admittedly bad) video from E3 this year. SHowing realtime Nvidea 6800 Ultra witH PS2 and PS3 effects.

Here are the screen shots

I know that all new games, etc up the level of detail, etc. But if this is the first time I have really seen a video of Pixel Shaders used to any good effect. The video is a hand held camera but combining it with the detailed screenshot you should get the idea.

The future is bright and more of a reason for ditching OpenGl in R4 to go over to DX for the next project.

True. I probably will ditch 'GL for the next one. More pressing though is a way to use all the new features from R4's scripting language. I can do some pixel shader stuff with a mod to R4's shaders, but it is kindof limited.

That video looks awesome. Doom 3, Unreal and Half-life are going to be superb. Unreal looks the best at the moment, but from what I know of the iD development team the displaced texturing that makes Unreal so good will probably be in Doom 3 before it ships

I fail to see the reason why you would have to ditch GL. Don't want to start a flame war here, but the real problem is the market share of low-nd and very low-end graphics controllers (you know, those brilliant integrated Intel Extreme Graphics, and to some extent those so-called DX9 parts such as GF-FX 5200 (oh, did I mention GF4 MX ?)).
OpenGL is cut in half : one part is the strong, well-thought API that has been around for more than 10 years and is being used by countless CAD, simultation and other kind of serious graphics applications; the other part is the nasty mess of extensions that expose bleeding edge technology you sometimes can't get in DX (ie reg combiners on GF3/GF4-class hardware). Some major problems have been sorted out, others are in the pipe. OpenGL 2.0 will be announced at SIGGRAPH. Future looks good
And back to shaders, GLSL is no that bad Drivers just need to mature a bit.
