Correct. I replaced Crossfire Vega 64 with a single Radeon VII and the overall experience is much better. Crossfire, I assume, was causing some sort of microstutter the whole time. FPS stats looked good (around 90fps) but it still felt choppy and laggy. With Radeon VII non-Crossfire, the stutter is gone. Not to mention other issues like OpenGL being broken with 2 cards installed, etc. It's not worth it.
