Hi everyone,

I've been using OBS and a twin PC setup to stream, but am suffering with screen tearing and an ever so subtle slowing down of the stream every now and then. It's genuinely minor, but the screen tearing is more obvious. Here's my setup:

GAMING LAPTOP
Acer Predator G9-593
GTX-1070 GPU
16GB ram
Default settings in Nvidia control panel other than using DSR and V-sync set to "Fast" (out of interest, having this set to "Yes" or turning on V-sync IN GAME made the screen tearing far worse)


STREAMING PC
Ryzen 5 1600
GTX930 (I think - just basic)
16GB ram
HD60 Pro (captuing gameplay feed from Predator via HDMI)
HD60S (capturing camera feed)

OBS
Latest version

Sample video of improved tearing (having set Predator GTX-1070 to "fast" and turning v-sync off in game)

OBS log file of my stream from this week is here: https://gist.github.com/ccd62e03667abfbcbd7815957fbc3f89

Again, no screen tearing or minor slowing down of frame rate perceived on my gaming laptop. Not sure if the log offers any help, but thanks in advance for taking the time to check this out!

Best wishes,

Ed

Ok, so if anyone finds this thread and wonders what the solution is, I've found it myself eventually. (Big thumbs up for the help.)

In the gaming laptop's Nvidia Control Panel, go to "Manage 3D settings", and change the following settings:

Monitor Technology -> "Fixed Refresh"
Vertical Sync -> "Fast"

Problem solved. I'd done this previously, but the Geforce Experience driver update clearly ignores my request to leave my settings alone.
