Fm Down by the Riverside crash to desktop

[covert_caedes]

By the way, if the "Frontend Acceleration" setting in the advanced video menu is supposed to disable running the Frontend in a thread, then that setting is broken.

However, setting com_smp 0 in the console works and after restarting I can frob the picture without a crash, but the following messages are printed:

"Frontend acceleration" is the user-side name of cvar r_useParallelAddModels, which controls job-based parallelism inside frontend.
And cvar com_smp controls the original two-thread parallelization which was present in Doom 3. We used to have a troubleshooting switch for it in the menu, but later we deleted it because this parallelism seemed stable enough.

If you are interested, it is described here: https://wiki.thedarkmod.com/index.php?title=Tracy:_timeline_profiler#Gameplay
