I rarely play anything from the past 5 years but when I do there’s a noticeable difference in how the games are rendered compared to up until the early PS4 era. Transparent voluminous materials like hair or foliage have this fuzzy pixelated look to them, and there’s a lot of rasterisation that looks like it’s being rendered on the Sega Saturn. Then there’s tons of odd shimmering going on everywhere, and I’m not sure if it’s due to dynamic resolution scaling, ambient occlusion or dynamic reflections
Overall games don’t look quite as sharp and defined as older games though they simultaneously have lots more detail. It’s weird
I’ve heard that a lot of the issues of TAA and upscaling aren’t as obvious when you render them out at 4k and also probably when you sit farther away from the screen, so if you game on an “old” PC monitor at close distance you are just not who these solutions are made for.
