My computer has 20 GB on VRAM but it appears that Unreal Editor still crashes. Can anyone help me figure out why?
The output from STDOUT is exceptionally long - here is the end of it, which does have some errors.
I would appreciate it anyone has some advice on how to keep it running.
I am using Ubuntu 20.04
