Digital Foundry : AMDs FidelityFX Super Resolution is finally here, and we’ve been able to test it out across a number of titles. The idea here is pretty straightforward: to dramatically increase performance while minimising the hit to image quality. So the questions we had going into this one were simple enough: how does FSR actually work? How does it look in comparison to native resolution imagery? And how does it stack up against top-end temporal upscaling solutions, like the excellent technique built into Unreal Engine 4? We can answer those questions today, but what we cannot do is offer any comparisons to Nvidia’s DLSS: test material simply isn’t available.
