Sean, It's just a matter of application frame rates and the CPU consumption that compiz incurs (in compiz and Xorg processes). So on the Nexus maybe use glmark2-es and es2gears to look at frame rates.
A test for disabling XSync completely (which will cause bugs but be a great performance comparison) would be to write a stub XSync function and LD_PRELOAD it into compiz. I will try to do that soon. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1049214 Title: [nvidia] XSync usage is a massive bottlenecking factor (nvidia performance regression in Compiz 0.9.8+) To manage notifications about this bug go to: https://bugs.launchpad.net/compiz/+bug/1049214/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
