Hi All

ive been streaming with these settings with magic the gathering online and also league of legends.

today I wanted to stream Shogun Shadow Tactics and I get massive lags/fps drops (in the stream not the game)

I tried also with window capture full screen everything also with exactly the same settings as for league of legends, still the same.

I dont get why this can be - any clues?

thats the part of log i did first with league of legends, small fps drop / lag at start then all fluid (friend watched stream) then shogun all just lagging / stuttering

Your CPU cannot keep up with live-encoding your video.

Try reducing your resolution to 720p, decrease FPS to 30, or use the superfast or ultrafast CPU preset (will decrease quality). You should also use the Lanczos filter to increase quality.

Hi I tried everything you said (should be somewhere in that log) however I can also do that again tomorrow - going to sleep now - if it would help if I do it again

Talking about downscaled res in Video settings right? my normal res is 2560 1440 on screen.

so i did your settings again - this happens: and the cpu % in obs doesnt go very high so i don't understand...? :(

Try 720p 30 FPS
*EDIT*
I saw previous log with 1080p 60 FPS.
Last log is partial.

Maybe you are rescaleng twice:
rescale ONLY in video settings and leave it unchecked in output settings,

last log is not partial, its everything after i changed settings coming after the previous log to show with the 720 and 30fps
also i only rescale in video and not in output tab

so i really dont understand how league of legends works with no probs and shogun just doesnt, i think also civilization 6 doesnt work, but i would have to try properly if that could help?

Because League isn't very GPU-intensive and for the other games you're pushing the GPU which is generating lagged frames in the log. Reduce load by capping the FPS (via Nvidia Profile Inspector or using Vsync) and maybe lower your GPU-based settings in the game.

Hi ok I can try that, howver playing league I have ~200 fps and that works. hmmm
So should I cap it at 60?
