In this article are benchmarks of six different desktops (Unity, GNOME Shell, GNOME Classic, KDE Plasma, Xfce, and LXDE) on five different GPU/driver configurations (Radeon, Catalyst, Intel, NVIDIA, and Nouveau) running the very latest Ubuntu 13.04 "Raring Ringtail" development packages to look at the latest state of the Ubuntu Linux gaming OpenGL performance.
This particular PPA has fixes / performance improvements (especially for Nvidia blob) that are much more significant than some of the other times (especially for nvidia users), you may have heard similar things (but yeah, i get what you are saying).

I'm not sure what kwin is good for. I found it to be extremely buggy when i was trying it out, very recently. The window focus / shadow animation makes moving windows (with nvidia) slow until the animation is finished. their implementation of expo while great in theory, produced windows constantly being jittery / and other buggy behavior... I was kind of surprised at how buggy everything felt, so i didn't use kwin very long (or KDE for that matter).
Gnome classic and LXDE on the chart are using the same shade of red. Which one was performing better? Also, why was unity and xfce were almost the same shade of red as well. Why?! There are other colors other than shades of red. Purple, blue, green, orange, etc. There is no reason to have 4 bars be two different shades of red.
