Base textures are semi-decent however, and the Unity version that was used in the making of the game wasnt particularly outdated. The rest of the graphics are poor, with glitchy shadows flickering on and off on rocks and walls, shadows being at a very basic level even when set to High, etc.
I cannot understand why they thought this makes for a good visual experience. For example, take a basic HDR-like effect, and crack it up to 9999, and you've got this horribly ugly blinding white effect that inexplicably was perfectly acceptable to the developer. Not old outdated graphics per se, just very very poorly executed. The game basically is horribly optimized and wont run well on modern hardware. It wasnt a CPU issue either, as my CPU usage was around 40-50% (not very low, but still not very high either). My framerate hovered between 28 to 38 FPS, and thats with the GPU usage being as low as 18%. Maybe they are saved when you save your in-game progress, but I didnt manage to save the game because it crashed. You go to the Graphics Settings (Picture Quality settings), change stuff, and your settings will be lost when you start a new game.
I have never seen a more ugly buggy mess of a game in my entire life.
