I can also add to the optimization convo, I think? It kept saying I wasn't giving it enough RAM or VRAM, before it even got to the main menu. I had to close my browser entirely, and I even had to shut off discord. Once I finally got to the menu, I lowered the resolution and was able to play, where the framerate seemed... fine? Looked to be 60 or higher. It ran fine, but didn't run at all with like 20 browser tabs open. (I'm a tab hoarder, so I often exceed 20.)
Maybe there's some memory leaks?
