Core24 / project 18251 memory usage

[Z3R0]

There is something strange about the way core24 handles memory with project 18251. Only 1.3gb of vram is being used (out of 16 so there is plenty available) and at the same time the Fahcore_24.exe uses over 4gb of system ram. And on the GPU stats I see that the copy engine is working like crazy, my GPU is barely warming up (at 50c) so likely the Cuda cores are waiting for data most of the time.

So the question is: why does core24 use so much time copying data to & from system memory when it could be much more efficient if the data was stored in vram? This might not be the case but at least in my opinion it is what my analysis points toward...

Any other project runs just fine, the gpu copy engine sits idle and gpu temps closer to 70c.
