I solved my problem (now CS work in OpenGL with 40-60fps on 1280x800) by upgrading to kernel to 2.6.28-rc7 and: x11-libs/libdrm-9999 media-libs/mesa-9999 x11-proto/inputproto-9999 x11-base/xorg-server-1.5.99.2 x11-drivers/xf86-input-keyboard-9999 x11-drivers/xf86-input-mouse-9999 x11-drivers/xf86-video-intel-9999 9999 = live cvs/svn/git build. 1.5.99.2 is xserver 1.6 snapshot 2. When i start CS i have error with libGL but all work ok. Code: ERROR! mapping regions libGL warning: 3D driver returned no fbconfigs. libGL error: InitDriver failed libGL error: reverting to (slow) indirect rendering
