[Bug 988079] Re: [nvidia] Dismal compiz performance on HP Z600 with 30" landscape monitor

 

Kenneth,

I know the problems with glxgears often look like temporal aliasing.
However that's unlikely the cause unless glxgears itself reports a frame
rate lower than the vertical refresh rate. Temporal aliasing could occur
at any frame rate, I know, but that would lead to a slight lack of
smoothness. Not an obvious and consistently low frame rate like I
believe this bug is about.

FYI, in cases where an application reports higher frame rates than you
know you're getting from compiz, it is best to consult the "bench"
(Benchmark) plugin from package: compiz-plugins-extra. The bench plugin
reports the actual frame rate being achieved (from the composite and
opengl plugins). Just remember to change bench's key binding in CCSM
because the default Super+F12 apparently does not work.

As I mentioned in comment #19, a bottleneck in compiz' event handling
has been found. That may be related and is described in bug 1007299.

I will be doing more testing and debugging with the NVIDIA driver this
week. So hope to have more suggestions soon.
