Just played it. Not sure which options are on or off in the menu (please consider adding a checkbox to them). Frames hold more stable with various combinations of the settings. As I’m not sure which are on or off, I checked them each on and off to check performance. Best results were frames at 11-13 fps. Worst were 9-10fps, with a stable 9 with an enemy on the screen and 10 when alone.
The walls still appear to look like folded paper when walking through hallways, even with different combinations of the menu items but performance is overall more stable.
