I did some testing of a few opengl games, just for fun and by curiosity.
Card is nv25 (64mb vram).

- works perfectly
openarena tremulous xmoto frozen-bubble hedgewars neverball supertux2

- works with some problems
* teeworlds : perfect after a hack to workaround this issue :
       nv04_surface.c:246: nv04_surface_copy_swizzle: Assertion
`!(dst->offset & 63)' failed.

* foobillard : works but this error shows up :
	Mesa: User error: GL_STACK_OVERFLOW in glPushMatrix(mode=GL_TEXTURE, unit=0)

* etracer : first few seconds are very very slow, then its still very
slow compared to all the other games. Also some texture problems after
a recent change.

* bzflag : full screen mode broken but window mode ok. Fonts look
weird (apparently some random corruptions)

- fails
glest : needs mesa 1.3

I think it's pretty good overall :)
