Performance problem between 320.00 and 320.18
Anyone else experienced performance slowdown in this case?
Personally I have a 4x(fps) slowdown. Every other version have worked perfectly until 320.18.
Well I get the feeling that I'm alone with this problem .
The scenes are also rather "heavy" with lots of shaders, textures and so on.
I don't think I have this problem in simple scenes, but it could be hidden by other things.
just switched from 314.xx to 320.18 and see no measurable difference. i think you might check your control panel settings and run-throught your application with gDebugger with break on errors options checked.
I forgot to say that I'm running 4.2 core version.
The problem also exists in debug-context, and I get no errors from that.
in that case, you should disable features until you nail down the functionality that causes the slowdown. i use OpenGL 3.2 context. nothing even remotely esoteric, just rendering VAO's with vertex+fragment shaders, so there's not much to go wrong.
Thanks for the help.
The problem is that it works perfectly with other versions so before digging deep I have to ask others, because it could be a driver thing.
I switched back to 320.00(beta) and it worked as usual again.
