i have 1980x1080, and there was an option for this
I see. So the method I'm using to get the screen size is not working properly in your case. I will change that method with another one that can probably solve the resolution problem. I'm not sure if that can help with the FPS problem...
I am still working a bit on some of the other problems I found so I will probably have everything done by the end of the next week (around friday).
