Resident GPU rendering substantially reduces the CPU work for supported HD affine race scenes. Shared draw preparation also avoids repeating equivalent native and HD setup. A portable CPU renderer remains available for unsupported hosts and scenes.
- Adds experimental 32× and 64× internal-resolution choices in Display and the Higher Internal Resolution mod. The maximum is 64×.
- Keeps enhancements disabled by default. Higher Internal Resolution starts at 4× when enabled; sprites and HUD retain their original artwork.
- Preserves adaptive widescreen, the optional 60 FPS track mod, native cartridge saves and the existing launcher controls.
The matched 382×160, 8× widescreen workload used 83.8% less process CPU time on the older Windows i5-4670/GTX 760 qualification host with the resident GPU package. This is an incremental GPU/shared-preparation comparison with the same native execution configuration in both arms, not a direct comparison against v0.1.9 or an FPS claim. Other measured workloads were neutral/inconclusive. The owner played 16×, 32× and 64× on an RTX 3080 Ti and cleared the presentation; those play checks are not controlled performance measurements. Available resolution and speed depend on the GPU.
Fresh Windows and Linux packages use the pinned release engine. BUILDINFO.json records exact source and artifact identities; SHA256SUMS.txt verifies the downloads. Native saves remain separate from build-specific save states.
