I had the DX control panel set to use the debug version of DX9 (troubleshooting a SINS beta problem). When I fired up GC2 TA, the minimap in lower right corner was all white. Actually, I fired up TA and found the minimap white. I thought about it a minute and remembered I had the debug DX set. I set it back to the retail version and got the minmap back. Just a FYI to the devs.
