The new 64 bit TF2 update broke a few mods. One of those is the popular mod p-rec that’s commonly used by competitive players to record matches.
If you have it, make sure to swap to the in game system as soon as possible so you can avoid losing demos.
any idea if anyone will recreate prec?
No, but honestly idk how necessary it is anyway. The in game system is good enough for the most part.
