Read a little more and it looks like they only support newer OpenGL when opened as a core context. So you might have better luck with the newer snapshots which ask for a 3.1 core context by default. Is there any indication of why the newer snapshots aren't starting?

If it only supports OpenGL 2.1 it'll be almost impossible to support. OpenGL 2.1 is 17 years old. Not sure what Apple is thinking providing such terrible OpenGL support.

Not sure about it but it might be different if you install XQuartz and have Wine use that instead of native Mac rendering.

When you type /saveframetimes in the chat screen, what frame times are you seeing in %localappdata%\MX Simulator\frametimes.txt?

When you're getting 1 fps, what does the driver info in the graphics menu say?

Which version of the game are you running? Recent snapshots are 64 bit and 1.13 is 32 bit so there might be a difference there.

The most likely reason for super slow framerates would be software OpenGL rendering. Not sure what the best way to troubleshoot that would be on Wine/Mac.

Is it the installer or the game itself that fails on Crossover?

Try disabling threaded optimizations.

Recent snapshots have a /saveframetimes command if you want to check how bad the stutter is.

Make sure your tracks are directly in the "MX Simulator" folder and not in a subfolder inside that folder. If you do something like make a "tracks" subfolder the game will still see them but they won't be able to find their media.

If you type "/listfiles rider_body.jm" in the chat screen, what does it say?

When I add UI scripting I might try it.

UI do you mean like a overhual of the main menu? No, he means allowing user customization of UI and editor via scripting. UI stands for user interface so yes that would classify as customizing the menus and whatnot. Yeah, UI scripting is probably a misleading name since it'll really be for all the ...

Not sure what that is. Can you post a screenshot of it?

Maybe after the terrain optimization and new shading code. Those are my top priorities right now. I really want UI and editor scripting after that though. So actually, after those three things I'll start taking requests.

UID 18416 has been banned for one day. Next time will be a week.

The personal folder is "%localappdata%\MX Simulator". If you want a fresh start just rename it to "MX Simulator old" and the game will create a new empty one the next time it starts.
