Question / Help Stream low fps, game doesnt

[TheMyth]

When i stream one game, my stream goes perfect but the problem is when i try to stream 2 games at the same time. For example, when im finding a game of Dota i like to play Overwatch, but when i stream overwatch in front of Dota, the stream start lagging but my games dont, they run without any problem. (Also i cant stream Mafia 3 with the same that i stream Dota alone thats work perfectly)

Incomplete log.

Are you getting this problem in the log?

Try turning on VSync in Overwatch.

Post another full log where you are getting the problem.

try these settings : Encoder x264 , 3500, from video tab downscale resolution to 720p and from output tab untick "rescale output", CPU Usage Preset Superfast, profile main, fps 60 and in Advanced tab Process Priority Above Normal.

Your gonna need to post a log for much more help. Stream for a while at least a few minutes then upload that log.
Delete opencl=true from your x264 settings.
Try turning on VSync in Overwatch.

Try both of these, tell me if either of them work. If not make sure you get a log.

it doesnt lag with the vsync on. I have two question, what does vsync do exactly to overwatch and to the stream, and do i need to turn on vsync on every game that lags?

Thank you very much for your help.

VSync caps your game fps at your monitors refresh rate. Normally a game would run as high an fps as it can get based of a gpu or cpu bottleneck. Since it is using all of your processing power to run the game there is none left to encode the video. For some reason this still happens even if you set the process priority higher than the game.

Any game that lags you will need to turn VSync on to get a smooth stream.
