The RPCS3 Team released performance data for its PlayStation 3 emulator running on a modified PlayStation 5. Digital Foundry tested the setup using a Linux-hacked PS5 with firmware version 6.02 or earlier. The evaluation highlights both successful emulation and significant hardware limitations.
Emulation test results highlight technical barriers limiting official console game releases
Ridge Racer 7 delivered stable 4K resolution at 60 frames per second with minimal stuttering during testing. Resistance: Fall of Man showed frame-pacing issues but generally impressed reviewers. God of War: Ascension and Killzone failed to impress due to stress on the Synergistic Processing Units.
GTA 4 produced slideshow-like visuals regardless of the resolution settings in RPCS3. The PS5 struggles significantly when imitating the older hardware's SPUs, causing severe frame pacing problems. These results demonstrate why Sony ports so few games directly to modern consoles.
Digital Foundry anticipates that official emulation could benefit from the PS6's more powerful Zen 6-based CPU. This speculation points to potential improvements in compatibility and performance with future hardware releases.
