Turning of all shaders except 3d clouds gives me around 20 fps more. Turning off shader support altogether gives me another 20 fps and turning of 3d clouds yet another 20 fps. (I'm getting around 100 fps then). Interestingly enough turning off shader support but keeping 3d clouds enabled slows down the frame rate by around 20fps but no clouds are visible.
