Thank you very much for your help! Can we use the default system malloc again with the new .exe?
Edit: Game runs fine with default system malloc for 1 hour (rather than 10 minutes), after which fps still drops to 3 fps.
Same issue here. FPS drops to 0-5 after 10 minutes of multiplayer. Normally get 45 fps minimum on Ultra. I will do my best to PM some game logs later today.
