My OS is Win7 64 bit. Newest Beta drivers, however this problem has occurred on every driver release going all the way back to the first one that claimed to support Fallout 4 Crossfire.
Primary display is Dell U2515h 1440p monitor via Displayport.
ASUS Sabertooth Z77 motherboard.
If you need more info just let me know, thanks.
Are you definitely running the game in exclusive fullscreen mode? Because CrossFire will not function correctly if the game is not running in fullscreen mode.
I'm also having trouble with fallout 4. Crimson 16.4.2 has caused massive graphical corruption with Crossfire enabled, as you will see in the picture provided.
OS: Windows 10 64bit
Mem: 32gb Hyper X Fury
GPU: x2 XFX Radeon R9 390
MB: Gigabyte GA-990FXA-UD3
Display: Benq GW2760
That and there are silhouette textures and complete textures missing.
Sorry I forgot to specify, the game is in fullscreen. Tried borderless and borderless windowed with same results.
I also updated to the newest Beta drivers (4/28 I think?) and same problem - crashing and corruption. I've tried both using the default CF profile and forcing the Fallout 4 profile.
