Fun fact: there is hardware support for S3TC textures, but the boot ROM disables it because "licensing".
I have submitted a patch to Mesa for this that will hopefully be merged soon:However, I am seeing some issues with some of the textures not having proper transparency.

This has now been fixed, so if you compile the latest git version of Mesa everything will look normal.The sky [looks] quite red (I will try to post a screenshot).
You can try decreasing the rate of physics updates, for example by setting OPENMW_PHYSICS_FPS=15.On the profiler, the FPS seemed quite low (even with minimal settings), around 10-15, although the game seems smoother than I would expect with that. So, perhaps the profiler isn't reporting an accurate number? There is also no bar for 'gpu' and quite a big gap between the 'cull' and 'draw' bars, so I'm not 100% sure if the GPU is actually being used.
