Edit: I just tried changing the door opening/closing to use a vector interpolation to be smoother, just in case the movement may have been jerky for you. It should hopefully help a bit!

Thanks for the feedback! What about the doors was a problem? I made some adjustments to help compatibility with some playtesters, but it sounds like those fixes may have negatively affected you.
Would you be willing to share your PC specs so I have them as a reference?
