So this is a weird one. Hopefully it's some simple thing I'm doing wrong.
Basically, my Crossfire setup - dual 290's - is showing good scaling in both Unigine and 3dmark. But when I fire up a game - so far have tested FarCry 3, Natural Selection 2, War Thunder - I am getting 0% scaling or even a bit of negative scaling.
-Crossfire logo (upper right) is displaying in all benchmarking software and all games - I am not running windowed/full-windowed or anything like that
-**Both cards are reporting proper utilization in GPU-Z whilst in game**
-Temps are well below throttling for both cards, for GPU and memory
-Have tried both 14.4 stable and 14.7 beta drivers
-Not a PSU issue - drawing max 600W from the wall with a 750W 80+Plat PSU - besides, Unigine draws more power than the games
-UPLS is off, using the downloaded tool
-Dual 290's (inner card is water cooled)
-Gryphon Z97 mobo
-750W Seasonic 80+Plat
-144hz ASUS monitor, 1080P
I've googled about and found zero people reporting similar issues, so I'm really hoping someone can help me debug this
