Hi all, Here's a patch to expand the graphical options in the "Video Settings" menu.
Firstly, the resolution selector has been changed to a drop down so you can just select the intended resolution instead of needing to scroll through them individually.
Next a slew of options to help increase performance, they're mostly self explanatory (they're made so you can change them without needing to restart, so you can experiment) but to go through them:
Background - enables/disables rendering the background tiles
Ambient Occlusion - enables/disables ambient occlusion (darkening in corners)
Depth of Field - enables/disables the blurring mostly seen at the end of the level and in cutscenes
Simple Spiders - replaces the normal animated spider swarm, and replaces it with a simple 2d version
Outside of Depth of Field, personally I would consider lowering the resolution first before touching any of these, especially on 4k displays. That said, hopefully with these you can tune the experience to your liking and get the game working on more hardware.
If you run into issues with any of these options, please let me know so I can fix them.
