Everyone already knows the performance is terrible, so I’ll just share my experience so you have a further example to compare to. I have a 13900k, 64gb of ram, and a RTX 4090, playing on a 1440p ultrawide monitor. I got 35 fps at the main menu and in game on a brand new map w/o building a single thing. Turning off motion blur and depth field increased this from 35 to 50 fps.

Not a single other graphics setting changed the performance at all. I turned off every single setting I could or set it to the lowest possible, and still only got 50 fps.

This is impressively bad optimization, I actually can’t recall another game recently where changing the graphics settings literally did nothing to fps. Just stay away from this until they fix it.
