Well, I’m not an expert in the field of gaming, but there has been all of this hype about DirectX 10 from Microsoft and how awesome it’s going to be. I agree that it looks really very awesome and very realistic, but nobody ever looks at the alternatives. I recently came across this image that compares images from DirectX 10 and OpenGL 2.1. Now, OpenGL 2.1 is an open source graphics library which is used for most Linux games and graphics stuff. Well, here is a comparison of the two:

Now, I don’t know about you, but I think that the graphics rendered by OpenGL 2.1 look even better than DirectX 10. I’ll be excited to see what OpenGL 3.0 can accomplish and I’ll be even more excited to see what games they have to offer to Linux at that time.
Also, there has been some discussion of this image on the opengl.org forums. If you’d like to read through it, click on this link. It might help answer some questions that you might have.
