Here’s the thing though, when you’re CPU-limited (and a lot of the games that struggle on current gen are) the upgrade won’t do much.

You should expect better resolution, ray tracing and possibly better image quality if devs implement PSSSR and it’s better than whatever upscale solution they’d use instead. Maybe if a game is pretty close to hittong its frame target it’ll give you a smoother performance but don’t expect much last that
