Did you test the fps cap removal? Because for me the game has no GameUserSettings.ini (probably since it has its own file where it saves all the settings to) and creating one doesn't help either. I found an alternative way by hex editing the config save file ConfigSlot0.sav. Just wanted to ask first before changing it.

Hi. The fix was working the last time I tested it. Maybe something changed in the meantime. I'm away from my PC so I can't confirm it right now. If you say you have a new solution, feel free to change it. :-)
Added it as an alternative just in case.
