I found a solution of "triangle-texture" trouble on my HD 4870 with 512MB.
Hardware: Core2Duo E8400 @3GHz, 8GB memory (3.5GB visible), ATI HD 4870 with 512MB (localVRAM=536870912, 512M).
Software: XP SP3 32bit, A2CO 1.62 with latest beta patch.
Reason (I think): bad "nonlocalVRAM" value detection.
How to repeat: fly with a plane over the Chernarus big cities from one to another.
Solution: install Catalyst 10.4 driver and boot at least 1 time with pagefile >= 512MB.
How to bring the problem back: reinstall the Catalyst 10.4 driver with disabled pagefile or install any other version with any size pagefile (in fact I tested only these driver versions: 8.10, 9.8, 10.3, 10.5, 10.12, 11.1, 12.4, 12.6).
Full description is under Spoiler:
Could anyone test my solution please? I want to report the bug to BIS or even to AMD if it need.
