I have a strange problem. When using GLSL and a PBuffer with wglShareLists, performance is suddenly dropping heavily on my ATI 9600 with Catalyst 5.5. This problem arises even when the PBuffer is only created but not used and only if I’m using shared lists. Has anyone else encountered that problem?
It’s not really a bug, and things work fine and according to spec. It’s just that there has been a performance problem a couple of driver revisions when sharing shaders across contexts. This was fixed not too long ago though, and I just check the newly released Cat 5.6 and the fix is included.
unfortunetely the performance drop is still there . Is there any public information about what is fixed in newest drivers? I don’t need information that game “ABC” will now work in 1024x768. I just want to know the exact fixes.
