All, I have modified this bug to just be about a very specific problem I find on my machine. If you're concerned about general performance of compiz 0.9.8.0 with the default settings then please look at bug 1024304 instead.
** Description changed: + (This is no longer the primary performance regression bug for compiz + 0.9.8.0. Look at bug 1024304 instead) + Comparing graphics performance in a two-monitor configuration, I find the gles2 branch is 25-40% slower than trunk. This would not normally be surprising, however the slowdown REMAINS even when I turn off the new rendering features in the gles2 branch: framebuffer_object, vertex_buffer_object, always_swap_buffers So both branches should be using the same code path. But gles2 is still dramatically slower than trunk using two monitors. The good news is that this bug only affects benchmark results and seemingly a little lag. The physical frame rate achieved with two monitors still seems to be higher using the gles2 branch, meaning it drops from 60Hz to 30Hz much less often than trunk does. NOTE 1: This regression was allowed in compiz 0.9.8.0 because it is generally only visible in benchmark results. Meanwhile, physical compiz rendering performance (as reported by the compiz Benchmark plugin) is higher in compiz 0.9.8.0 than previous versions, in most cases. NOTE 2: If you're just worried about fullscreen game performance, then you don't need to wait for this bug to be resolved. You can get optimal graphics performance with unredirect mode.
