Persistent Stutter/High CPU (Rendering Lag) with NVENC on Ryzen 9 3900X/RTX 3060 - Log Attached

[1Cut1Kill]

I am experiencing persistent stuttering and noticeable performance degradation during my multistreams to Twitch and Kick. The issue primarily manifests as Rendering Lag or high CPU usage spikes, even though I use the dedicated NVIDIA NVENC encoder.

My latest log, which I've attached below, showed a minimal dropped frame count (around 0.2%), but the actual streaming experience is significantly choppier and laggy than this suggests. I need help diagnosing why this lag is occurring intermittently, especially when running multiple outputs.

Rendering lag, you need to reduce load, your GPU is slightly overloaded. It isn't horrible but there's definitely room for improvement.

Before I have you make other changes, fix this Scene. Move one of the captures to another Scene or just delete it. Having more than (1) capture source in the same Scene can cause interference & since things aren't too bad, there may be some improvement.

It wouldn't hurt to spent some time updating your encoding settings. Clean things up a bit.

I noticed the dirty start. If OBS is crashing all the time, SE is suspect. SE replaces core elements of OBS with their slop. Plugin creates a ton of issues.....
