screen freeze

hi im new to boxing and was successfully playing duel char for a few days, however when i added a third char i get my main screen freezing as often as a few times per minute, i can only get back to normal by disabling broadcasting and using my hotkey to swap to another screen over and over,
here is my config:

I see nothing in your profile that sticks out, but it could be a hardware issue since you were doing just fine until you added a third account. You can use the following link to help you find a possible bottleneck on your system:

cheers for reply i couldnt find a bottleneck as such but lowering ingame settings seems to have worked
