Question / Help OBS preview choppy when i set games to 120/144hz

[quell_italiano_li]

Hi guys, i had a look around to find a solution but i'm really confuse and i didn't find any solution to this.

Despite some frames i can loose when i'm streaming or recording, my main issue is that if i set my game (for now it is Battlefield 1) to 120/144hz OBS preview is choppy (without streaming and recording). If i set my game to 60fps everything runs very smooth in the preview window; but i loose the 120/144hz in game.

I have 3 monitors, extended desktop. Tried to set different frequencies for each monitor, vsynch or not, gsync or not. Tried everything in Battlefield 1 video settings menu.

So i'm here to ask you if is there a method to play games at 120/144fps and let OBS runs smooth at 60fps and let me record very smooth 60fps videos?
If not....will a capture card solve the issue and how?

My rig is:
i7 7700k 4.2ghz
8gb RAM 3000mhz
mb ASUS Prime Z270-A
Gigabyte AORUS 1080Ti
SSD 850 EVO
2TB HD Western Digital (where i record videos)
Logitech C922 webcam
3xMonitor Philips 272g5dyeb 1920x1080p@144hz G-sync

Here is the last log:

It's normal behavior. If your main moniter is running at 144 and other at 60, yes they will appear choppy. Don't worry it doesnt afect your stream.

This is an issue with videocard running different HZ ratio with multiple monitor. Nothing you can do there unless you buy 3 144hz monitor

I already have 3 monitor @144hz. I tried every combination of hz. I know it doesn't affect my stream but I would like to have smooth recording. With or without obs. Never mind if I have to run another software but I would like to sort it.

You can try Gameshow and Xsplit, it's not related to streaming software. It's a behavior since windows 7. It's a issue between Windows and multiple monitor. It's been like that for years and creator update messed that up even more.

If i game fullscreen and watch a youtube video or stream, my second screen will be choppy.

You can search online, there is countless of post about that behavior. The only possible fix is to watch your stream from another PC.

I'm surprised to learn that 3 monitor running at 144hz still have the issue. I know if i put my screen to 60hz, everything run smooth.

what I noticed is that my preview was choppy when my GPU was overloaded, Star Citizen overloads a 1080ti even, since its so early in alpha and badly optimized. Though if I use Dxtory to limit fps to 60 in Star Citizen then the preview runs fine.

I wish you would have the option in OBS to run the preview on the CPU instead of the GPU, should fix the problem we are having.

I play BF1 at ultra @120fps and my gpu is around 70/80% if i remember well. Anyway i tried to set "low" graphic details but the choppy preview is always there.
