Hello, I have 2x graphic cards Sapphire RX480 Nitro+ 8Gb OC set in CrossFireX, but when I´m playing Battlefield 1 I get 46-60 Fps, 1980x1080, details on ultra. But when I´m playing only with one graphic card RX480 I get 60fps max and min 56fps. And game runs smoother. I have AMD Crossfire enabled in AMD control center. In AMD control center I have 1. RX480 setup as primary, which is in PCI-E 1 and monitor is connected into it. And second RX480 is in AMD control center setup as joined (secondary) card and it is in PCI-E 2. But I have bad performance in another games.
My PC set:
AMD FX-8370 4,3GHz
MB ASUS M5A99X R2.0 EVO
32Gb RAM
power Corsair 850W
Windows 10 64bit
SSD Kingston HyperX 480Gb
HDD WD Caviar Black 1T
2x Sapphire RX480 Nitro+ 8Gb OC
Thanks for help.
Battlefield 1 does not support MGPU in DX12. Run DX11 if you want to crossfire....Also, make sure to turn on the AMD Crossfire Logo in Wattman General Settings. It will show you when Crossfire is active.
