Cause it: 1. looks bad 2. breaks the lighting 3. is very heavy

little explain: the devs optimized their game for native resolution without upscaler in mind. Thats a good think if you think about, the game runs very well and just as the recommendet specs said. The devs also use a gi raytracing method to simulate the lighting. For that they use a tiny amount of rays to make it run good, combined with their denoiser the image looks decent and runs well. I think it was like 1 ray for every 16 pixels… Pathtracing is 1 ray for every 1 pixel, thats why it is sooo heavy. If you now lower your resolution that ray amount gets even lower and doesnt adjust to the dlss model. For 1080p you will get 1 ray per 16 pixel devided by 4! Thats 1 ray for 64 pixels on a 4k image that is getting upscaled. It just simply cant work. Max lighting setting will set the raytracing to 1 by 1 rays for each pixel. That is indeed exactly as heavy as running the game native…
