Not sure how to review this. Its still portal which is a great short adventure. But it runs like crap, I have a brand new 4070super and the default settings had the game chugging along at 20ish fps (to get it to run you have to open the nvidia app and get it to optimise the settings for you). The game itself is basically a tech demo for nvidia, and i think it does a very poor job of doing that. It runs poorly and all the upscale frame genny stuff just leaves everything with this strange plasticy wobbly feel to it, you cant help but notice how drastically the quality decreases while youre moving and then you feel the quality increasing when you stop and its in those moments where the game engine is catching up with you that it feels most uncanny.
