I have been having some constant crashing issues on the Mann vs Machine Co-Op since yesterday and it's really annoying me because my experience on the new gametype is unplayable ever since it happened when I was playing with my friend in a random Mann vs Machine server.
Sadly I haven't got a clue about the crashes but somehow I found 3 crash dumps laying around in the "team fortress 2" folder outside of tf where people usually tell you to download skins and that to. I did in fact report this as a bug on the same day as the crash but I haven't got a reply since.
If you think you know how to fix this then please help me and put down a solution and I'll try out the solution, thank you kindly for reading.
EDIT: Crashing has gone! Thanks to Eventyr for suggesting to turn off Multicore Rendering because it fixed the problem ^^
