[SOVLED] Performance Issues with Compiz

Hello,

I have noticed a few problems with Compiz Fusion. It is very slow so I have tried a few things :

-Enabled Loose Binding Increase Performance to Good Level but causes window redraw issues.
-Enabling Indirect Rendering Fixes that. But then there is no more Vsync. So there is tearing when I move windows

How do I enabled Vsync and keep good performance. I have nvidia 180 and latest version of compiz.

Here are the contents of the xorg.conf.

Thanks for the help. I am still very new with Arch Linux

Re: [SOVLED] Performance Issues with Compiz

Are you sure your machine is capable enough to handle Compiz?

Re: [SOVLED] Performance Issues with Compiz

With nvidia drivers, I believe the Load  "dri"    line should be commented out.

Not sure if it's still needed in latest Xorg (it shouldn't hurt though), but in Section "Screen" you might want to add Option         "AddARGBGLXVisuals" "True"

Downgrade to nvidia-17xx solved all problems. Enabled loose-binding also to increase performance and no more redraw issues. Even Vsync works now !

Re: [SOVLED] Performance Issues with Compiz

loose-binding needs to be enabled for all NVIDIA cards AFAIK. Then manually set your refresh rate and enable vsync, and all should be smooth.

Re: [SOVLED] Performance Issues with Compiz

I have exactly the same problem.

I have a Nvidia card, so I have to enable loose binding, but then I get the window redraw issues. So I enable Indirect rendering, then I get the screen tearing!
No amount of tweaking the vsync options in compiz or nvidia-settings can fix the issue.

Anyone else solve this, without downgrading their nvidia drivers??
