I originally posted this over on Reddit, but IslandDog requested I post this over here. I'll just quote my original post from Reddit.
A couple days ago I read that in DirectX 12, Ashes could use a mixed array of AMD and nVidia GPUs. Until about an hour ago I only had a 980Ti in my computer. Being the adventerus type I have procured an AMD GPU to slap into my system to test it all out. I have both the AMD and nVidia drivers install (Latest versions of course) and I have MGPU checked in game. The 980Ti is the primary card in the array.
Unfortunatley Ashes is not detecting the AMD card and when I try to open the Radeon Settings program, it simply says the driver is not installed. Odd as Device manager says it is. MSI Afterburner says it is. I even reinstalled the driver just to be sure. Has anyone else played around with mixed GPU's in Ashes and had a similar issue? If you have, what was your solution?
I'll post my specs below in case they may be of any help.
- Intel i5 2500k @ 4.8Ghz CPU
- ASRock Z77 Extreme4 Motherboard
- 8Gb G.Skill Sniper 1600Mhz Ram
- EVGA GeForce 980Ti
- And of course the AMD R9 280X secondary.
- Windows 10
EDIT: I was finally able to get the Radeon software to see the drivers... I had to hook a display into the card and restart. The only issue now is to get Ashes to not CTD once it tries to bring up the main menu.
I've also tried doing this with stock clocks just to make sure there wasn't some sort of instability causing this.
Right now I'm stuck on getting this to work with both cards and MGPU enabled. If this is something the devs are activley working on I'm more than happy to use my computer as a test system to benefit the work being done.
EDIT: Off topic... I've also been unable to get my game over 60FPS even on low settings. This seems really crazy considering the hardware I have. Perhaps this is a point of interest in the process of optimization? Here's a link to my benchmark runs to give you an idea as to what may be going on. https://app.box.com/s/82eya27609iyeku6g6oyy2m9mam7wzeh
