Highball
Which renderer to use
Highball can run each game through three different Direct3D translation layers. This is what the database knows for this title — empty rows are open questions, not failures.
| Renderer | Verdict | Evidence |
|---|---|---|
| DXVKDirect3D 9-11 over Vulkan | Untested | no report yet — send one |
| DXMTDirect3D 11 over Metal | Reported | community reports |
| D3DMetalApple's Game Porting Toolkit | Reported | 1 report |
No dated Highball run yet. When one lands it records the renderer, the engine build and the macOS version it was seen on — which is what stops a verdict quietly rotting. Send one.
Notes
Reported perfect on DXMT on an M4 with the steam, corefonts and vcrun2022 recipes on the Wine 10 engine r5, and playable on D3DMetal on an M1 with the Wine 11 engine r12. The MSCLoader mod loader needs winhttp=n,b in the DLL overrides field, not the environment variables box, and both reporters run it that way (highball#203 was that mix-up, and the loader works for them since). The M1 report has some stutter where there are many light sources, which the reporter puts down to the game being CPU-bound. No frame rate was given and nothing was measured here. Two more perfect ratings on the default engine r26 (M4 on DXMT for over two hours, M3 Pro on D3DMetal). On an 8 GB M1 on the Wine 11 engine the frame rate fell from about 90 to under 20 while inspecting the car (highball#335), not reproduced here.
Known issues
After a long session the game freezes, and the log fills with "msync: warn: node memory pool exhausted" (242 million lines in one report)
What helps Fixed in the default engine from r17, which environments on it pick up by themselves once Steam is closed, and in the Wine 11 engine from r13. Environments on the Wine 11 engine never change revision on their own, so pick the newest one, x64-crossover26.3-r19 with Highball 0.10.10, on the environment's Full page under Advanced, Engine. Until then, set the environment's Synchronization to None and stop the environment before playing
Why A bug in msync, the fast synchronization mode: a wait on several objects that lost a race left the thread registered in Wine's background process and nothing removed it, so the pool ran out and that process kept growing (highball#224). Measured on an M4 with macOS 27.0 with a reproducer, 2026-10-01: the wineserver grew from 30 MB to 77 MB in 30 s on engine r12 and stayed at 39 MB on r13. The Wine 10 default engine had the same fault (19 MB to 83 MB in 30 s on r15, 17 MB flat on r17); the freeze itself was reported on r12

Before installing anything, it is worth checking whether the game already ships a native Mac build.
Common questions
Does My Summer Car work on Mac?
My Summer Car has no native Mac build, but it is reported to run on Apple Silicon through Highball, a free open-source compatibility layer. This comes from community reports rather than a Highball test run, so treat it as a reasonable expectation rather than a guarantee.
Which renderer should I use for My Summer Car?
DXMT. Highball can translate Direct3D through DXVK, DXMT or Apple's D3DMetal, and the right choice varies by game. The database records DXMT for My Summer Car. Highball uses it automatically when the game has a row; to set it by hand, open Settings, then Environments.
