Vulkan editor is very crashy on older cards due to memory pressure. I have to switch to OpenGL to work on the unrelated bugs.
I'm attaching the details of the particular failure I had (see VulkanMemAllocFailure.txt). It doesn't seem reasonable to allocate a 6144x2048 RT when we have such a tight memory situation
RHICreateTargetableShaderResource2D(SizeX=6144, SizeY=2048, Format='\f', NumMips=1, Flags=0, TargetableTextureFlags=4, bForceSeparateTargetAndShaderResource=false
1. Have a low RAM card
2. Run the editor in a 1080p resolution
3. Open some more Windows, e.g. I tried to open DestructibleMesh editor
