With non-KMS intel video drivers I got around 1000FPS but after updating the kernel to 2.6.30 and xf86-video-intel to 2.6.x+, I only get 200FPS at most. Debug shows: LIBGL_DEBUG=verbose glxinfo | head libGL: OpenDriver: trying /usr/lib/dri/tls/i915_dri.so libGL: OpenDriver: trying /usr/lib/dri/i915_dri.so libGL error: dlopen /usr/lib/dri/i915_dri.so failed (/usr/lib/dri/i915_dri.so: cannot open shared object file: No such file or directory) libGL error: unable to load driver: i915_dri.so libGL error: driver pointer missing libGL: OpenDriver: trying /usr/lib/dri/tls/swrast_dri.so libGL: OpenDriver: trying /usr/lib/dri/swrast_dri.so Shouldn't it be looking at /usr/lib/libdrm_intel.so instead? Reproducible: Always Steps to Reproduce: 1.Update to a kernel that supports KMS 2.Update xorg-server and xf86-video-intel 3.run glxgears Actual Results: <200 FPS, every 3D app is slow. Expected Results: +1000FPS in glxgears, 3D apps with useful performance.
It looks like your mesa needs rebuilt, since that is what should provide i915_dri.so. If that doesn't fix your problem, please post output of 'emerge --info' and 'emerge -pv mesa'
Had my VIDEO_CARDS variable still using the old "i810" designation, it started working as soon as I added "intel" and recompiled Mesa. Thanks!
