Just upgraded my card from an Nvidia 2080 to a Radeon 6900 XT and immediately my game started to lag on any and all camera movements. In port, in-game, on ultra all the way down to low presets, and everywhere in-between. With mods and without mods. I was getting over 100 FPS with the old card, averaging 40 with this one. WoWs seems to be the only game adversely affected. Cyberpunk baselined at 155 FPS and runs smoothly. GPU utilization is spiking into the 80% range just sitting in port.
The game ran smoothly with the Nvidia - nothing has changed besides the graphics card.
