Game slow down then crash every 5-20 minutes

Helllooooo, I’m experiencing an issue in the 2151 graphical experimental where the game will suddenly grind to s snails pace(turns taking 5-10 times as long to process as normal) and then after about 5-10 turns like this the game crashes with a Microsoft Visual C++ Runtime Library error. “This application has requested the Runtime to terminate in an unusual way. Please contact the application’s support team for more information.”

It goes at least back to the 1269 Experimental(this has been happening to me for a few days, I’m submitting a bug report because it has finally corrupted one of my saves when it occurred mid-save) and it seems to occur regardless of what I’m currently doing in game. I’m going to try reverting back to an earlier experimental and see if it happens.
