When bump map on vehicles is on and the sun is out anywhere the sun is reflecting on the wirble is whited out. Gunner position or driver position.
The gear portions of the gun and the centers of the barrels whited out. The whited out portion changes position with head movement. Like its supposed to be the suns reflection but is just whited out instead.
ATI HD6950 2GB in xfire (acts the same in crossfire or not)
11.10 Drivers - 11.9 cap4 profiles (last xfire profile for 11.10 drivers) (11.10 is the last whql driver that is not buggy 11.12, 12.1 and 12.2 pre release all have issues of their own)
Tried fresh install of drivers (removed driver in cat install manager, deleted all ATI folders even hidden ones, removed all reg enterys for ATI and did a clean complete re-install)
W7 64bit
I7 2600k @ 4.7GHz
8GB Ram
All bump map and other graphics on
2048 textures
AA off ingame
AA on 16 or 8 in CCC (tried both) override app settings - 16x is an big improvement over maxed in-game AA
Antisotropic filtering on use app settings
Tesselation use app settings
Cat AI on quality
Verticle refresh always on
AA mode adaptive multi sample
Problem disappears when vehicle bump map on self is unchecked
Also should note there is a severe hit to frame rates with xfire off and on one card driving thru clutter with everything maxed out at and at 16x AA. xfire on doubles frame rate on the ground with everything maxed out.
