Folks at Digital Foundry have found that the latest PlayStation 5 system software update makes some video games perform just a little bit better.
Digital Foundry discovered this change by accident while testing the revised PS5, which became the subject of much discussion due to its smaller heatsink (it turns out the smaller heatsink makes no difference). During their test, Digital Foundry noted that their launch PS5 slightly outperformed their revised PS5. Upon investigation, the team found that the older hardware had the latest firmware, while the revised PS5 was not. After updating the PS5’s revised firmware, both consoles performed identically.
Then Digital Foundry started testing some games and noticed that Check and Devil May Cry 5 were a few percentage points faster with the new firmware in some scenarios.
“I have benchmarked Check in graphics mode with its photo mode unlock fps, Devil May Cry 5 Special Edition in RT mode, god drop, and Resident Evil Village,” wrote Richard Leadbetter. “Check and DMC5 don’t vary by more than one percent on a run-by-run basis and yet the new firmware runs those titles two to three percent faster than before – a curious state of affairs. residue has dynamic elements that adjust performance slightly every time, while I didn’t see any change at all in god drop. I wonder if it might be a system level ray tracing optimization? A few percentage points in certain scenarios is hardly groundbreaking, but intriguing nonetheless.’
Sony’s official patch notes do not explain the performance improvement.
