Strand based hair causes a VRAM l3ak. The l3ak increases incrementally every time you open the pause menu. Disabling strand hair stops the l3ak entirely. This is reproducible 100% of the time. this did not happen with me in any previous FC game.
interesting. How do you see that? Also when opening and closing the menu the snow effect gets broken, if there's wind enabled. Could that be for the same reason?
