Thank you for your answer!
I tried to put the Virtual Memory to 32768 and 131072, but still crashes. Every time I launch it I get a new error but it almost all the time say:
GPU Crashed or D3D Device Removed
GPU ran out of memory
What I don’t understand is why the project go so slow, before this issue i was running the game smothly in Epic quality and I was using 64GB of Virtual Memory. Now if I import the map to another project it goes extremelly slow and I can’t do anything.
Thank you again for your help!
