Something like that. Not only with VDPAU performance is bad. Also Xv video playback performance is poor. What I say is that VDPAU is even worse than with Xv. All that if KDE OpenGL compositing is enabled. With effect disabled or using XRender the performance is better.
Actually I'm noticing that when the effects are active (OpenGL), everything is slower and heavier in KDE. The response of the effects and when switch windows are a bit slower.
How I can reset to the default nvidia-settings configuration? I want to be sure the problem is not because I've changed something in other versions of the driver.
Sorry for my English if I can not explain it better.

Which version of OpenCL is supported in this version?
It's good to see more OpenGL 4.3 support, CUDA 5.0 is looking very interesting. I'm looking forward to a 310.x stable driver.
Please stop whining about Wayland and KMS, the first is not at a usable state yet and the latter is not needed for the Nvidia driver.
KMS is not necessary for the Nvidia driver. KMS is not the one holy modesetting solution. Nvidia have their own. And now let me blow your mind: Nvidia's modesetting is in the kernel too! Even bigger mind blowage: They've had it way before KMS even existed!
I selected "raster" as Qt Graphics System and performance is better.
I think that performance in "native" (X11) should be better.
http://userbase.kde.org/Desktop_Effe...raphics_SystemWhich graphics system is used depends on the distribution defaults. For the Compositor raster is recommended especially if the NVIDIA driver is used.
Only raster is supported by Qt. Native is un-maintained and buggy.
Ok, then the nvidia installer should select "raster" by default. At least this beta did not do that on my system.
Now my question is, why in the KDE site (and forums) raster is recommended "especially" with nvidia drivers?. Why nouveau drivers has better performance than nvidia drivers in native X11 (in KDE)? (at least with my graphics card)
That can be only with very rare gfx cards with 1 performance level only. All newer cards are usually slower as they just run with the default boot speed.
