Laggy Stream + Inputlag feeling ingame


New Member
Hey guys, i need your help!
- CPU: Ryzen 7800x3d
- GPU: RTX 4080
- RAM: DDR5 6000 CL32
- Monitor: LG OLED 240 Hz 1440p
OBS settings: (attached files)

Internet Connection: Down -> 64Mbts Upload -> ~30 Mbts DSL(Telekom)

I already tried a lot of settings but it doesnt really help. I just can feel lag/inputag while streaming - my aim seems to be less smooth (cant do micro adjustments like i usually do offstream)

If i watch my POV i see a lot of pixels on fast movements.
I dont know may it be my Internet?

Hopefully you can help me out!

File > Settings > Advanced > Sources > Enable Browser Source Hardware Acceleration, set this to unchecked fixes input lag when OBS is running. Anything else like Discord, Steam (Steam > settings > interface > disable bottom 4 sliders except last) or running Browsers should also have GPU/Hardware acceleration disabled for no input lag.

Make sure under Nvidia Control Panel > Manage 3D settings > add the OBS exe, and set the preferred refresh rate to Highest, otherwise OBS when running may be messing with your screen refresh rate. Disabling the OBS preview is also recommended.

You can also try disabling Multipass and Psychovisual Tuning, they both use cuda cores and eat into your GPU usage, if you're near 100% GPU usage those can cause extra bottlenecking. Otherwise the rest of those settings look fine. Make sure you're running OBS as Administrator if you don't have HAGS enabled in Windows.
