Render Acceleration on integrated intel video
 
After upgrading my Slack from 12.0 to 12.1 on my laptop i've noticed the reducing of 3d productivity. Compiz working slow, karamba widgets doesn't allow to watch movies.
The required information:

I suspect that productivity decreasing is related to unusing "RenderAccel" option. I don't see where are the conflicts or any troubles and why it doesn't applying :\
Any ideas?

You are mixing nVidia options with the Intel X11 driver. Type man intel to get a list of X11 options for Intel driver.

Dah, Compiz or Beryl works slow with Intel graphics. Intel's graphics in Linux uses Mesa for a lot of its tasks. Also Compiz or Beryl is experimental, so I suggest do not use it on a daily basis. For performance, do not use any eye candy effects in Linux. XFce is a good light weight desktop and window manager.

I've delete nv options strings. The same situation. Options that linux driver doesn't support are not using. That's not reason why 3d so slow

I realize that my videocard not so fast as I wish and that linux drivers for it worse than windows, but in older version of slack with this kernel and xorg configs Comiz worked on a medium preferences. That's why I started this thread :\ There was something that allowed to get much more points in glxgears and to use compiz comfortable.
