Hey guys,
So I added a second 7970 to my rig recently but I'm having some issues. First, I had some insane screen tearing so I used vsync and frame limited like rivatuner and it got rid of some tearing but it brough insane stutters in games. So I read somewhere that vsync in crossfire cause issues so I bough a 144hz monitor.
I no longer got screen tearing (awesome monitor) but I still got some weird performance that doesnt feel right with my setup. (4770k @ 4.2 with 2X7970 OC). One example would be in BF4 on all ultra I got between 50 to 70 fps on 1920X1080. Checked MSI afterburner and the GPU stats are either not showing up (all stats are at 0) or my GPUs are both at around 60%. I'm using a 1000w PSU,2X4G RAM and 1 bridge between the 2 cards. ULPS was disable trough MSI afterburner. I'm using 14.7 beta drivers.
Any idea what could cause this ? It also seems to be the case in other games like divinity original sin.
Thanks !
