No more "in bed with nVidia", PLEASE! Original IL-2 had that and was a pain to those who did not have a "green" card. Sure making SSAO an option would solve this and/or contacting AMD on this how they support SSAO.
Anyways, using lowtex and nossao mods now = bliss
For those with problems, clear the cache before enabling these mods/fixes.
