Thanks for the link! Sadly, it doesn't look like that's an option for me. :/
The Flow mask is definitely a bit pricey, but I could probably put away some money for it or something similar. It also addresses one of the issues I have with other elastomeric masks which is that I struggle to do anything in public that I fear might draw attention to me due to heavy (psychological) masking, and a lot of the others look very attention grabbing.
Chromatic aberration! When I played R&C: Rift Apart on PS5 I was taking screenshots and genuinely thought there was some kind of foveated rendering in play because of how blurry the corners of the screen looks. Turns out it was just chromatic aberration, my behated.
Hate film grain too because I have visual snow and I don't need to stack more of that shit in my games.
