For more than a year now, I've been running Catalyst 10.10 no problem. I'm a "if it ain't broke dont fix it" kind of guy and updating drivers is something I only do if there are problems with the originals. However, I recently purchased a game which requires an update to the latest drivers. Here are my specs
-ASRock 870 EXTREME3 AM3 AMD 870 SATA 6Gb/s USB 3.0 ATX AMD Motherboard
-1 x SAPPHIRE TOXIC 100282TXSR Radeon HD 5850 1GB 256-bit GDDR5 PCI Express 2.0 x16 HDCP Ready CrossFireX Support Video Card
-XFX Black Edition P1-750B-CAG9 750W ATX12V
-AMD Phenom II X4 965 Black Edition Deneb 3.4GHz Socket AM3 125W Quad-Core Processor
-G.SKILL Ripjaws Series 4GB (2 x 2GB) 240-Pin DDR3 SDRAM DDR3 1600 (PC3 12800) Desktop Memory
-Windows 7 home edition 64-bit
As mentioned before, everything is just fine with 10.10. As soon as I update to 11.12, the graphics go insane, almost like the models are being stretched all over the place, green lines all over the screen, etc. The glitches happen in Mass Effect 1 and 2, WoW, and Starcraft, but do not occour when playing metro 2033. Unfortunately, I can't get a screen shot, it just shows the desk top, and Im living out of town for a few months so I dont have a camera either. I know its probably not a bad card, after all, it works fine with the orignal drivers. I have already reverted back to 10.10 and everything went back to normal. I have tried reseating and at this point, Im not sure of what to do. I know it has to be something firmware related and I would sincerely appriciate input from someone with experience with this kind of thing.
