Yes a day/night difference. This adult game is also really a MUST try on the oddysey+ https://www.patreon.com/ProjectH
pledge $4 and you can download the full version (you can then immediately cancel the ‘subscription’ if you want, otherwise it will become a monthly recurring charge). Set SS to 200%, use that 2.0 mod and then slide the in-game ‘pixel density’ slider to the right and you’ll be simply amazed at how good it looks. It does get my 2080TI to its knees though at those settings but man, it just looks perfect. Really fun, and graphics wise it’s much better than that (super popular) crappy Vr Kanajo game, never liked that one.
BTW on that project page you can also download the free demo. I’m not sure if that pixel density slider is in there though, you really need to see it with that slider to the right, big difference.
