I now remember I ran into this a while back just once before I realized what I had done, but I found it odd because I’m thinking GPU, but I had disabled virtual memory on my windows machine, because I have 32GB of ram on that machine and a decent GPU and thought I could get away with it regarding performance. Despite this I encountered a crash and error while working with a relatively small scene saying I ran out of video memory. I turned virtual memory back on windows and it hasn’t happened since.
