Sony Patent Hints at PSSR 2.0 Upgrade for PS5 Pro to Reduce FPS Drops and Resolution Cuts
Since the launch of PS5 Pro in November 2024, Sony has been working to improve visual quality and resolution in games optimized for its most powerful console. While PSSR has delivered strong results in some titles, other releases have experienced visual glitches and graphic issues that affected performance and image stability.
That is why Sony, led by system architect Mark Cerny, is working closely with AMD to bring key parts of FSR4 into PSSR for PS5 Pro.
How PSSR 2.0 Aims to Fix FPS Drops and Resolution Issues
A new patent filed by Sony at WIPO, titled “Graphics Processing”, gives an early look at the changes planned for PSSR 2.0. The update is expected to arrive in the coming months as part of the dev kit.
The patent describes a new method that will help avoid FPS drops and reductions in native resolution in PS5 Pro games. In simple terms, developers may no longer need to lower a game’s base resolution in order to use PSSR.
The key idea mentioned in the patent is real-time quantization. When a game faces a heavy data load, frame rates can drop for a few seconds. Instead of lowering the native resolution, PSSR 2.0 could temporarily reduce the use of CNN to stabilize performance.
CNN stands for convolutional neural networks, a type of machine learning system that PSSR uses to reconstruct part of the image and increase its resolution. When FPS drops, PSSR 2.0 would reduce the use of CNN to bring performance back to normal, without cutting the game’s native resolution.
According to the patent, real-time quantization reduces the use of neural networks when the GPU load is too high. This helps smooth out FPS drops, especially in fast-paced games.
For now, this is still a technical concept, and it remains to be seen how well it will work in real games. If it performs as expected, Sony could solve one of the main issues players have noticed with PSSR on PS5 Pro.
In other PlayStation news, it’s been reported that Sony won’t raise the price of the PS5 despite rising RAM prices, and will rely on software to cover the gap.
