compiz performances

[Guillaume]

When I use compiz (in unity and kde) Performances are horrible, when I use normal resize, I get about two frame second. When I switching workspace using ctrl alt + key, my fps drop to 20 and the same thing when I move the scrollbar overlay (without grab it) also, the v-sync is not stable... That is the performances issues I found when I upgraded to compiz 0.9.x on natty.

If disabling Sync To VBlank fixes the performance problem then you're seeing bug 763005.

You can test this by installing package "compizconfig-settings-manager" and then:
  System Settings... >
  CompizConfig Settings Manager >
  OpenGL >
  untick "Sync To VBlank"

Please try this.

I tried this, but It don't seems to solve the problem for switching workspace, or for the overlay scrollbars lagging. I use the benchmark and I get about to 600 frames/sec but It show 450 when I switch between workspace, but more I got window, more I got a freeze before the animation, witch is very fine, with 450 frame/sec. but bigger is the little freeze, faster is the animation, like if compiz in overall was freeze during a time. The same thing is done when I do the normal resize. I can post a video later

[Daniel van Vugt (vanvugt)]

It's very likely you're seeing Nvidia-specific bug 92599 which contains a simple workaround editing xorg.conf.

[Guillaume (gufide-g)]

I can see it's not related with my graphic card, because It use 100% of one of my core when I use the normal resize, or switching when I got a lot of window. I got an i5 2.23, I don't know why it can lag like this I post a video on youtube showing my screen, we can see the cpu usage in the graph, and we can see that when I start to resize, everything froze, including the little panel graph... here's the link:

This bug did not happen with compiz 0.8.6 or kwin (with both vertical sync and opengl enabled)

[Daniel van Vugt (vanvugt)]

Please also check your compiz refresh rate setting:
  System Settings... >
  CompizConfig Settings Manager >
  Composite >
  Refresh Rate

It should be the same as your monitor's vertical refresh rate. If the refresh rate is too high then of course it will consume more CPU than normal.

Ideally Detect Refresh Rate should be ticked ON and you should have the workaround described in bug 92599 configured. In my experience that has solved all framerate issues with Nvidia chips.

[Guillaume (gufide-g)]

My maximum framerate is at 60 and I tried with and without the Detect refresh rate and I tried with the bug 92599 workaround and it does the same thing, the cpu is used at 100% again when I resize. When I resize by one or two pixel I got a fine framerate, but I can see again that it use a lot of cpu, about to 40%, but when I resize faster than this, I see my cpu core used by 100% by the application during the resize, and it's not happen with other window manager.

[Guillaume (gufide-g)]

I repeat: this is the application resizing that using the cpu, not compiz, but with all other window manager, it doesn't happen! I try with another opengl compositing window manager, kwin, and I don't get this, even when I run kwin from unity and resize.
