I currently have a frame rate problem when playing battlefront with crossfire enabled.
On max settings I only get about ~30FPS with my two R9 270s crossfired.
My first thought was wow this game is really graphically intensive, so I oc'ed the cards, no change in frame rate.
I then lowered the graphics quality all the way to low, and only got to about ~40 FPS. After looking online at benchmarks
this was clearly the wrong FPS as it would seem a single 270 could get around 45 FPS on ultra.
So I reset the settings to ultra, looked at my GPU activity and lo and behold they were just idling there at 30% utilization.
Finally turning crossfire off I got to about 45 fps on ultra on a single card.
Looking around online there were a few questions close to mine but they all involved graphical glitching of some sort as well, I have not seen any such glitches just low frame rate.
Also from this video :Battlefront Beta - Ultra Graphics AMD R9 280X Crossfire On/Off test Windows 10 - FPS Count - YouTube It would seem that crossfire works just fine for this guy.
Any help would be appreciated,
