Frame skipping / drops and choppy playback on >120 fps video playback if certain use flags are not enabled

Basically when watching a stream on Twitch.tv that is being broadcasted in fps above 60, meaning that the encoder uses 120 fps there are tons of skipped frames. It basically never stops skipping the frames. Even after reaching ridiculous numbers like 10000 skipped frames it just never stops. After enabling the following use flags "layers.d3d11.force-warp: true" and "gfx.swap-interval.egl: true" the problem subsides, skipped almost completly disappear. I think if I turn off hardware acceleration it prevents the frames from skipping too.

By the way I will attach my hardware info down below: OS: Windows 11 22H2 CPU: 13900k GPU: 3060 TI

I'm not sure if this behaviour is expected or normal but it's kind of weird. Maybe it's a problem with my hardware and not a software problem. I'm hoping it's not a faulty gpu or something. Would be nice if somebody could reassure if this is a problem with my gpu or not.

Flags tested: "gfx.swap-interval.egl" "layersd3d11.force-warp" and turning hardware accel on / off "layers.acceleration.force-enabled" also "layers.prefer-opengl".

Any testers apperciated! Best regards, Syntractrix.

I totally get how frustrating it can be when you're dealing with frame skipping and choppy playback during high FPS video streams. It's great that you've been proactive in testing different flags and settings. From what you've described, enabling "layers.d3d11.force-warp: true" and "gfx.swap-interval.egl: true" seems to have helped alleviate the problem. Another thing you can try is updating your graphics card drivers to the latest version, as that can often resolve performance issues. Additionally, you might want to make sure that your hardware acceleration settings are in sync with the flags you've adjusted. Keep in mind that streaming quality and browser performance can also depend on the specific streamer's setup.
