A Careful Look At PS3 Games On PS5
Digital Foundry has tested PS3 emulation running on base PS5 hardware, and the results are genuinely interesting. The experiment shows that Sony's current console can handle some PlayStation 3 software better than many might expect, especially when the original game does not lean too hard on the PS3's unusual SPU setup.
That last point matters. In simple terms, PS3 emulation appears to look much healthier when the game being tested does not make heavy use of the Cell processor's extra units. When those parts of the old hardware become more important, the PS5 has a much tougher job recreating the same behavior through software.
GTA: Episodes from Liberty City is one of the clearer examples. Under emulation, the game puts real pressure on the PS5 CPU and can perform worse than it does on original PS3 hardware. Raising the image to native 4K does not fix that core issue, because the problem is not only about graphics resolution.
Other tests look much brighter. Heavenly Sword, a launch-era Ninja Theory game, can reach 2880p while holding a fairly steady 30 frames per second. That is a striking result for a PS3 title running through emulation on a standard PS5, and it gives the whole test a nice retro-tech spark.
The stronger results seem to appear more often with early PS3 releases, but the picture is not limited to launch-window software. Some later games also show positive signs, which suggests the story is more complicated than simply saying older titles work and newer titles do not.
What The Test Suggests
- PS3 emulation on PS5 can work well when a game is lighter on SPU usage.
- CPU-heavy cases can still fall behind the original PS3 experience.
- Higher resolutions are possible in some games, but they do not solve every performance problem.
Digital Foundry's conclusion is that PS6 may be the machine with enough CPU power to deal with PS3 emulation more comfortably. That fits the mixed results shown here: promising in the right conditions, but not yet clean enough to make the challenge look simple.
Implicit Conversions has been working in this area, so there may still be a future where PS Plus Premium includes PS3 Classics. For Z-retro, the takeaway is balanced: the progress is exciting, but the PS3 remains a special case that needs careful handling.
