Review FSR de la DF: Big FPS Boosts, But Image Quality Takes A Hit:
Ultimately, I feel that FSR is most useful at 4K in its ultra quality mode, but its utility drops off fast at resolutions and quality modes lower than that.
Conceptually, I also think FSR has a less competitive position in the market of image enhancement technology. If a game only offers basic upscaling, FSR will do a better job, but why would a game only have basic upscaling? Every major engine on the market - whether it's from Ubisoft, Epic, Capcom or Square-Enix - has some form of TAA upscaling already. And because they're accumulating and reconstructing from more available data, they deliver improved results up against a single-frame spatial scaler.
AMD has said that the technology may evolve, so we may well see new and improved techniques - but the bottom line is this: right now, there is absolutely no doubt that FSR can deliver stratospheric performance wins, but the higher the gain, the higher the pain in terms of image quality compromises.
