Local Recording - Really bad flickering Playback!

[tinkle007]

Hi All

I am that close to pulling my hair out, No matter what I have done or tried I still get flickering play back
My main goal is to stream @ 720p and record at 1080p on a dedicated SSD using NVENC NEW

I have played about with priority or even different encoders, used different media players (VLC, media player classic)

9700K 4.8ghz
16GB 3600mhz
1080ti
Windows 10 2004 version
Game mode enabled or disabled (Tried)

Hi Rockbottom,

Thank you for responding so quickly, I tried everything above and I am still getting the issue! But it did intrigue me to dive a little further and I tried recording with the exact same overlays but used display capture rather game capture and the flickering went away!? tested this 3-4 times and works perfectly it seems.

Would you know why Gamecapture is causing it and display isn't ? my only problem now is I have to be careful when streaming not to alt tab as I am using one monitor and people will see my desktop which isn't end of the world.

Cool!

I'm not sure but if Display Capture works, roll with it at least for Modern Warfare. Just make sure not to have a Game Capture & Display Capture in the same Scene as it can cause flickering too.

Hmm I got the issue again, for the fun of it I downgraded my drivers from the latest nvidia to 445.87 and I never got the flickering. so it looks like the new drivers 452.06 (and even previous 2 versions) have something new that OBS doesn't doesn't like.

any idea? I really want to use the latest drivers as they are more stable compared to the 445.87 but anything later than this OBS hates.

I'm still running Windows 1903 but I'm using Studio Driver 451.77 without any issues so I'm not sure if the problem is actually the newest Nvidia Drivers, Windows 2004 or OBS.

446.14 was the last Game Ready driver before W2004 was released but if 445.87 is working good I'd stick with it for now.
