Crossfire and MULTI GPU are highly dependent on how the game supports them. You have not even said what game you are trying to play and in what DX mode 11 or 12 or other? In general both Nvidia and AMD seem to be moving away from crossfire/sli support as DX12 and forward puts all of this support on the game developer and their engine alone. It has nothing to do with the GPU drivers and any optimization profiles for the games. Once you give some better information someone may be able to offer some better targeted help.

- All drivers are current and up to date along with my AMD drivers.. If I uninstall my AMD drivers and revert all the way back to Radeon-Software-Adrenalin-Edition-17.12.2-Dec19
I have no issues running that older version of Radeon with Dual Cards and Monitors.. Install tha latest version and nothing but issues it's not Crossfire related etc.. It's really AMD software related.
Okay you gotta a couple options to try without reverting to that old driver. One is disable HDCP. Many find that helps. Also many find that making sure they have the latest mouse driver also fixes this. Other than that it is a known issue, just a question of when and if they fix it.
