Hey, for like 2 days my stream fps is dropped somewhere around 10-15(?) after streaming for a while. It might occur more often after i alt-tab and get back to game. Temporary fix is to delete and add game capture again. Any suggestions?

did that, tested streaming 10min and it worked, although it worked yesterday with Battlefield 3 for 1hour and CSGO for 28minutes. i'll continue testing..

btw, i haven't ever had any stream fps problems so it might be with the latest test version only.
