Hey, apologies for not seeing your support thread earlier!
It is difficult for me to say why so much VRAM is being used at this time. We recommend relatively modern hardware in order to run it with 1080p, 60 FPS so perhaps this is possible if we are trying to push beyond that limit.
Can you please advise at what resolution you are playing?
I also noticed that while a lot of VRAM was being used, the GPU itself was barely being used at all. Have you noticed any correlation between the 2?
If possible, a video would also be much appreciated. Perhaps we can find a pattern as to when a great deal of VRAM is being used.
Any other information you're able to provide would be much appreciated
