The RPCS3 PlayStation 3 emulator for PC has become one of the first emulators to officially support AMD's FidelityFX Super Resolution (FSR) technology, highlighting the perks of AMD's open-source approach to its upscaling technology. 

RPCS3 allows PC gamers to play PlayStation 3 games on their systems. Adding FSR to the emulator will enable users to upscale many PlayStation 3 titles to higher resolutions, even those that do not allow gamers to change the game's maximum rendering resolution. This addition can enable PC users to achieve higher levels of image quality using RPCS3 for games without support for higher rendering resolutions and allows users of lower-end GPUs to upscale games to higher resolutions in a more performance-friendly way. 

The video below from RPCS3's developers highlights how useful this technology is when emulating Red Dead Redemption on PC. 


    RPCS3 is the first emulator to support AMD's FidelityFX Super Resolution (FSR) technology thanks to our lead graphics developer kd-11 implementing it on the 6th of August. FSR is incredibly useful for RPCS3 in a number of ways.

FSR allows users to have better visuals at a similar level of performance, which is incredible for users with low-end graphics cards that struggled with using Internal Resolution Scaling. The few games which don't work with Internal Resolution Scaling can also utilize FSR without any issues, which is a huge improvement over playing at a native 720p resolution.

Even users with high-end graphics cards will see a lot of usage out of this as games which have a high RSX (PS3 GPU) load can lower frame-rates when scaling up to 4k. With FSR, you can use an internal Resolution Scaling value of 1440p, and then upscale to 4K with FSR. Visuals still look amazing, and frame rates will be higher.

Why FSR and not DLSS? 

Nvidia's DLSS technology has a temporal component, and AMD's FidelityFX Super Resolution technology is a Spatial Upscaling technology. This means that AMD's FSR technology doesn't require data from previous frames to upscale them, and Nvidia's DLSS technology does. This factor alone makes Nvidia's DLSS technology unsuitable for emulators, as it would effectively require a form of temporal anti-aliasing to be implemented into every PS3 game. It simply isn't going to work. 

FSR can be added to an emulator because AMD's technology is Open Source, and it does not require data from older frames to work correctly. This allows RPCS3's development team to use AMD's technology and implement it without making any major changes to their emulation/render pipeline. It even works on games that don't support RPCS3's resolution altering features. Another perk of FSR is that it works on graphics cards from AMD, Intel, and Nvidia.

I hope I'll eventually be able to play Red Dead Redemption 1 with this Quote
