Stream lagging even when OBS shows no dropped frames

Hello I just streamed on Twitch in 2K for the first time and Dual Format using Enhanced Broadcasting, while also multistreaming to YouTube using the 1440p encode from Twitch. I was playing Trails in the Sky 1st Chapter in 1440p and my stream started lagging during some battle animations, even though OBS showed no dropped frames due to encoding lag, and around 100 frames due to rendering lag after 3 hours. I fixed it by simply switching the game back to 1080p, but I wanted to get some insight on why this was happening and why I OBS wasn't reporting it. Thanks!

I attached a log file and here is a timestamped example of the lag during the stream if needed https://www.youtube.com/live/deXXYr-S_rs?si=9p_SFA_UzLVAG-6J&t=3956

1. The Hardware-accelerated GPU scheduling ("HAGS") feature in Windows is currently known to cause performance and capture issues with OBS, games and overlay tools. We recommend disabling it via these instructions as a troubleshooting step. Be sure to restart after disabling it.
2. Multiple Game Capture sources are usually not needed, and can sometimes interfere with each other (Main Layout and Vertical Main). You can use the same Game Capture for all your games. If you change games often, try out the hotkey mode, which lets you press a key to select your active game. If you play games in fullscreen, use 'Capture any fullscreen application' mode.
3. Display, Window and Game Capture all interfere with each other (Main Layout and Vertical Game Only). 1 per scene.
4. The encoder is skipping 4.6% of the frames because of GPU overload. Read about troubleshooting tips in our GPU Overload Guide.

If still having issues, reduce the Maximum Video Tracks to < 6. If still having issues, post new log.
 
Rendering Lag is GPU overload, plain & simple. If you have it, load reduction is priority. There is something in your Scene Collection that is lagging really bad. I would test with a New Scene Collection, add just (1) source.

21:28:24.083: ┣tick_sources: min=0.001 ms, median=0.132 ms, max=142.563 ms, 99th percentile=7.714 ms

Any reason why these dropped frames didn’t show up on my OBS stats?
 
That's not dropped frames, that's source timing. It's slow, your system is on the back foot from the get go.

There was no dropped frames in the log. Just lots of lag of all varieties, you got the trifecta, audio, encoding & rendering lag. Your scene collection is massive/possibly bugged & just adding to the load, that's why I suggested the new collection. See if the system can function without all the baggage.
