Update from 5.1.0 to 5.1.1 causes video memory crash

I’m using the smaller CitySample map for a production. It worked fine in 5.1.0 and we made several modifications and animations in it. Somehow (by accident or an auto-update), my engine updated to 5.1.1. Now, when I open Small_City_LVL, the map successfully opens for a few seconds, but then crashes saying “Out of video memory trying to allocate a rendering resource…”

I’ve tried:

  • Closing ALL other applications
  • Rebooting PC
  • Setting the engine scalability to Low before opening the map

The project is also now taking 20-30 minutes to open, when before it was <5 minutes. Bizarre…

I have a GTX 2070 Super and 32Gb of RAM.
