I’m getting some crashing in 5.3.1 when switching GPULM to “non realtime” mode. This only seems to happen in certain levels. I haven’t been able to isolate the reason why.
I first noticed this problem after building from source. However, I am having the same issue in the stock launcher version of 5.3.1
Below is the error code from that.

Anyone else having a similar issue?
I have the best luck, clearly
