Carmageddon (1997) freezes a few seconds after race starts

Hello , I have been trying to get Caramageddon MaxPack to run on PCem with minimal success. The game loads fine however when the race starts the game will freeze shortly after. I have tried the released version as well as the latest dev build with the same result.

Host CPU i7-6700k
Tested running game on Windows 98 and MS dos 6.22
both 3dfx and software rendered versions.

If the game is run on windows 98 (dos) I am able to ALT TAB back to the desktop so PCem does not appear to be crashing just the game itself.

I'd like to help resolve this, I believe PCem to be the best way to relive classic OS's and Games short of playing them on the actual hardware they were made for.

Thanks,
Chris.

Does anyone have a suggestion for a process monitor for windows 98 to see what's actually being requested from the OS when the game crashes?

Process Explorer 11.11 should work ;)

No luck, that program only shows processes running under the windows kernel. DOS games don't register at all ::

This is looking like some horrible floating point issue. Might take a while...

Carmageddon used to work for me, but it's been a while since I tried it.

Update, carmageddon now crashes back to a desktop in windows 98 immediately when the race starts rather then freezing at random.
