You might not be fully aware of this, but PC gamers with RDNA-based GPUs in their graphics cards share quite a lot in common with anyone who has a PlayStation 5 or PS5 Pro. That's because there are quite a few architectural features common to both. However, while only RDNA 4 users officially get FSR 4, PS5 Pro gamers will soon be getting an updated version of Sony's PSSR upscaler, with Resident Evil Requiem being the first game to use it.
If your reaction to this is 'so what?', it's worth bearing in mind that FSR 4 and PSSR (PlayStation Spectral Super Resolution) stem from Project Amethyst, a joint venture between AMD and Sony for bringing AI-powered upscaling to consoles and PCs alike.
