Just logging a fault that unless you use the -winxp command with the latest 190 drivers (190.62 WHQL) I get blank textures. Also suffer with CTD occasionally.
I have used 2x8800 GTXs in SLI previously that don't have this issue with Arma 2 in this driver.
GFX: BFG GeForce GTX 285 OCX
Sound: X-Fi Fatal1ty
Mobo: ASUS P5N-T Deluxe (BIOS 1303)
CPU: Intel Woldfale E8400 Intel Core 2 Duo
Cooler: Tuniq Tower 120 (on the CPU)
Case: Cosmos S
Keyboard: Microsoft Natural 4000
Mouse: Razer Diamondback
OS: Windows 7 Ultimate 64-bit Final RTM Build
RAM: OCZ Reaper HPC 8GB (4x2GB) DDR2 PC-8500C5 @ 1066MHz
Display: Dell 2005FPW
PSU: Hiper Type M 880W
I do not believe this bug is related to 8gb of RAM, as when running with 2x 8800 GTXs in SLI, I had no blank texture bug with these drivers. Also, when using my GTX 285 with the 186 drivers, there was also no texture bug.
All components are at the stock speeds as provided to me by the manufacturers.
