Anybody else having regular crashing with PT enabled?

I seem to have an issue where the game crashes, i think it could be a memory leak?
Because both VRAM and virtual memory usage peaked at 98% usage before crashing:

Note in game usually uses about 75-80% VRAM(12gb of 16gb) and memory is usually similar.
I often seem to get stutters in game where VRAM usage increases at the same time.
