I can't get this to work at what I'd call an acceptable level - aside from the lousy Ubi launcher, every loading screen takes minimum five, up to ten minutes. Every fast travel, mission change, or death; any time the game reloads. I've tried GE, Experimental and Proton default, with/without gamemode, minimized the graphics, even reloaded from Pop to Cachy and still no dice. I think over the past week i've spent 10 hours staring at loading screens and maybe 1 total actually playing the game (which works fine, if you can get it to load!). It doesn't scratch my RAM, CPU or GPU; it's not a resource issue, it's just insanely slow.
