Good morning and thanks for your replies. @Wido : vendor is all nvidia, drivers appear to be working fine @Raster : I am getting excellent performance on the older opensuse 11.4, and also I tried installing Jeff's bodhi linux on which I also have excellent performance. So that at least rules out the possibility of hardware being the culprit. On my current latest opensuse however the problem remains. I installed a previous version of xorg from source, problem remains. I installed 2 different previous nvidia drivers, problem still remains. I compiled and installed the latest 2.6 vanilla kernel, still problem remains. I also tried recompiling and reinstalling r65800 directly (instead of creating and then installing rpms), and problem persists. I have tried adding / removing / tampering with every option in nvidia-settings, in the enlightenment configuration options, and anything related from nvidia documentation in xorg.conf. I have cross-checked xorg.0.log from all 3 installations and not found something wrong / different. So I'm back at square 1. I found previous posts stating that gles / xcb should not be used and to let autoconfiguration take place. Is this still the case ? Also I found a similar poor opengl performance thread by Jeff that wasn't eventually resolved. Maybe he can shed some light on whether he solved it in the end or if he is still having the same problems on that particular machine. On a side note, I noticed on all 3 systems that with compositor enabled, when dragging a windows around (terminal in my case), cpu usage is high. When using software rendering, it's 60% enlightenment 40% xorg When using openGL it's 85% enlightenment 15% xorg. When compositing is disabled, cpu usage is normal. So I'm still stumped and open to suggestions.
