Project P.I.T.T. Performance Fixes
Project P.I.T.T. 1.0.8 safer loading, black-screen/crash reports, the documented Vulkan launch option and safe save-first troubleshooting.
Update 1.0.8 changes loading to favor safety, even if it takes longer. For a black screen or crash, back up the save and try the documented Vulkan launch option as a diagnostic—not a guaranteed fix. September player reports remain COMMUNITY REPORTED, distinct from official patch fixes.
Official loading change and reported symptoms
The 1.0.8 notes say main loading should be longer, especially the first load, but safer. There is no official maximum loading duration. A slow first load and a repeatable crash are different symptoms; record what happens rather than assuming either that the game is permanently frozen or that the patch fixed every case.
| Symptom | Evidence date | Status and limit |
|---|---|---|
| Black screen, with or without audio | 7 September player post | COMMUNITY REPORTED; installed build not independently confirmed |
| Black screen / crash on Mac | August thread; 7 September follow-up | COMMUNITY REPORTED; follow-up says Vulkan did not solve that case |
| Startup freeze / lag before intro ends | 31 August–1 September thread | Historical COMMUNITY REPORTED symptom; developer described loading work, not proof of a new post-1.0.8 bug |

Try the documented Vulkan launch option
Steam's exposed launch configuration includes: “Project P.I.T.T. with vulkan renderer (in case you experience crashes)”. The alternate entry is present for Windows, macOS and Linux in the mirrored configuration. A developer reply in the Mac black-screen thread also suggests trying Vulkan.
Launch from the Steam Library and choose that named alternative if Steam shows the launch selector. If a previous choice was remembered, check the game's launch selection in Steam's properties. The Steam interface can vary; do not paste random crash-fix flags or delete settings to force the choice.
This is an alternative renderer diagnostic, not an official universal cure. One September follow-up reports that it did not help. Note whether the normal and Vulkan launches differ, then return to your prior selection if needed.

A low-risk troubleshooting order
General diagnostics: back up your save, record the build and operating system, restart the game after a large physics session, verify installed files in Steam, and check ordinary OS/graphics-driver updates. Try one change at a time so the result is attributable.
The older developer FAQ recommends disabling Retro Effect, lowering graphics detail and reducing resolution for low FPS. Those are source-dated settings suggestions, not proof that a new black-screen case has the same cause. Do not delete a save as a first troubleshooting step.
Earlier fixes still worth knowing
Update 1.0.6 addressed high-polling-rate mouse FPS, saving reliability and certain lost-tool recovery cases. Update 1.0.5 added Clear Items and Save & Quit; Clear Items is destructive cleanup and does not refund money. Preserve a backup and understand what will be removed before using it.
Update 1.0.8 also changes Spring Pads and movable pistons. If a particular contraption behaves differently, isolate that interaction instead of assuming a general engine regression.

What to include in a useful bug report
Record build, operating system, hardware, normal/Vulkan launch choice, whether audio continues, whether the problem occurs before the menu or only with one save, and the exact reproduction steps. Keep backup copies private unless you intentionally choose to share them with support. This guide does not diagnose a community report as an officially confirmed bug.
