Pretty much every new game runs poorly. Even the new Assassin's Creed game without ray tracing and upscaling can only get around 80 frame rates on an RTX 5080, at 2560x1440. Graphics are generally improving (and regressing a bit in some places) but the performance of many new releases just doesn't match the visual quality increase IMO.
that's because developers are using DLSS/FSR and frame generation as a crutch instead of optimizing their games
