I was having problems with GLSL in Oblivion (invisible bodies, mainly) before
upgrading Catalyst to 11.3. Now Oblivion works better with GLSL enabled
(without GLSL there are no shadows). The only problems I'm facing now are:
1. Not being able to use HDR and AA at the same time (minor issue as it's
difficult to get working even on windows from what I've read)
2. Poor performance in outdoor environments, but probably not related to GLSL
because the only thing influencing performance is view distance.

So for anyone having problems with GLSL I recommend trying Catalyst 11.3.

Tested on Radeon HD 5770, Wine 1.3.15 and 1.3.17.
