    Vega 64 Crossfire Issues


      Recently I purchased two Asus - Radeon RX VEGA 64 8 GB ROG STRIX during 2018 black Friday sales event. I felt it was worth the price and was led to believe that it would be an upgrade. I've never had any issues playing any of the games with my previous components playing in 4k @ 60hz getting 90-120 fps in games like World of Warcraft on high settings. I've upgraded a few items to compliment the new Vega cards and I'm only getting half the Fps in WoW 40-70 on high, and I'm forced to play at 50hz because 60hz setting will constantly turn my screen on and off every 10 secs. PLEASE tell me what I'm doing wrong? Any and all help would be appreciated!


      My original PC configuration was as follows:

      i7-4790k CPU

      MSI- Z97S SLI Kriat edition mobo

      Two Samsung 850 SSD's

      16 GB Vengeance DDR3-1600 ram

      Geforce GTX 1080 8gb FTW gaming ACX GPU

      750 Thermaltake 80+ bronze PSU

      Fractical Define R4 case

      Sceptre 50" 4k UHD TV/Monitor @ 60hz


      My upgrades from above:

      32 GB Vengeance DDR3-1600 ram

      Two Vega 64 in crossfire

      EVGA - SuperNOVA G3 1000 W 80+ Gold

          Do the two Vega cards work as expected individually?  On another note, if you are playing WoW in DX12 mode, I do not believe Blizzard has implemented MultiGPU support for the DX12 version of the game.  If you play in DX11 mode, you should be able to utilize the crossfire profile from AMD.
