On October 24, 2026, RPCS3 announced a Windows change that replaces the older NT heap with SegmentHeap for PPU/SPU recompilation. The project reported that recompiling Gran Turismo 6 on a 9950X3D went from 2 minutes 50 seconds to 1 minute 55 seconds, a 55-second reduction.
The change targets recompilation, the process of preparing game code for RPCS3, and RPCS3 said the benefit appears when many threads are used.
Why 48% faster means about 32% less waiting
The reported times make the two percentages easier to separate: elapsed time fell by about 32.4%, while the inverse rate of recompilation rose by about 47.8%. RPCS3 rounded the latter figure to 48% faster.
| Measure | Before the change | After the change | Difference |
| Recompilation time | 170 seconds | 115 seconds | 55 seconds less |
| Elapsed time, indexed to 100 before | 100 | 67.6 | 32.4% lower |
| Inverse recompilation rate, indexed to 100 before | 100 | 147.8 | 47.8% higher |
The indexed figures use the original measurement as a baseline of 100. The benchmark measures PPU/SPU recompilation time, not frame rate during gameplay, so it does not indicate a corresponding increase in game FPS.
What the result means on later launches
VideoCardz reports that RPCS3 caches compiled code for later launches. That means the shorter time in this benchmark concerns recompilation, rather than a delay that necessarily repeats every time the game starts.
