Question / Help Twitch Stream - Horrid FPS, Unwatchable Stream

[Donik]

Hello everyone. Probably a usual post here. New to streaming, and have been fighting with getting everything right. Trying to stream IL2 Cliffs of Dover. Suffering massive FPS loss when playing online while streaming. Streams fairly well if I play single player and all alone.

Could you post a log file of this instead? Would be the best way for us to be able to help.

Oh, I'm a doofus, I'm terribly sorry.

I might recommend using some downscale. Streaming at higher HD like that can often impact games. Try 1.5 downscale and see if it reduces the issue. Could also try 1.25 as well, but the problem might still persist.
