AMD has said it's going to be «evaluating» whether your RX 580 deserves Radeon Super Resolution (RSR). But it's only going to be doing that once it has gotten the new performance boosting feature playing nice with its Ryzen 6000-series APUs (those with RDNA iGPUs) and then with Radeon-powered gaming laptops.
So, you're a little way down the priority list, but at least it's not a hard 'no' to RSR hitting older AMD graphics silicon. Gotta take the positives where you can find them right now, eh?
AMD has only just released Radeon Super Resolution, a software based upscaler that's powered by FidelityFX Super Resolution (FSR), but doesn't require devs to pre-bake support into their games. That means almost any game will benefit from higher frame rates if you run RSR and your games at a lower resolution than that of your native screen.
It's effectively the same solution Valve has stuck into the Steam Deck to allow it to upscale to a 1080p docked display without sacrificing the performance it's capable of at 800p.
The catch right now is that RSR is only available in drivers for Radeon RX 5000-series GPUs and above. That means anyone sporting an older GCN-based GPU, such as the popular RX 400- or 500-series—or even the ill-fated Radeon VII—is out of luck.
That's a shame given that RSR's more powerful progenitor, FSR, is fully supported on all those graphics cards, so long as the game has it. But that doesn't mean RSR will never find its way onto older GPUs, it's just that it's at the back of the queue.
Speaking at the press briefing for the new Radeon software, Glen Matthews, AMD's director of software management, said that:
«Our next step is with the Ryzen 6000 RDNA products, so we'll be adding that capability, that's going
