Hey there! There is currently a known issue with what may be caused by lower VRAM graphics cards or with micron VRAM and Directx12. (The GTX 1060 3GB is a common one) There have been Error#132 crashes and performance issues that correlate with the Live Kernel Event errors, which would explain the FPS dropping to 0 at times:
Our team is currently investigating the issue, but DirectX11 is a workaround we’ve found successful so far. Hopefully, the triple buffering or DirectX11 (or DirectX11 Legacy) may be able to help with the FPS drops.
