OBS Enhanced Broadcast FPS/Lagging

[SmanUK]

When I have enhanced broadcast enabled I find my OBS fps in the bottom right corner drops (see image attached), this happen when I load a battle in a game, it is fine on the game main menu. If I try to do anything during the battle OBS lags, trying to get the task manager up lags. It's as if my CPU/Ram is maxed out with being used.
I've checked a couple of things, windows game bar is off, hardware-accelerated GPU scheduling is off, driver and up to date ect.

This is running on a new system, I did not have this problem on my old system. I have uninstalled OBS fully, removed all setting incase there is a conflict there.
My system should easily handle this:
CPU: AMD Ryzen 7 9800X3D
Ram: 64Gb @ 6800Mhz
GPU: Asus RTX 3080 FTW3 10Gb
Windows 11 Pro

My only through here which I've not tried yet is the CPU dose have an intergrated GPU. Could this be causing my problem? I know some people are going to say turn off enhanced broadcast but I need it to beable to stream at 1440p, so this is not an option, I also find this option make the game run smoother with it on. This was running fine on my old system.

Sorry forgot the log file https://obsproject.com/logs/NmH6PBTlDGFhsdXV

Rendering lag is GPU overload, load reduction is in order.

How does it run with the multi-out disabled?

The Keyframe error is something I haven't seen before but in every instance prior where I've dealt with such errors, it was a driver issue.

Look at the Profiler results at the bottom of the log. Both Audio & Video are lagging too far for 60fps.

Other issues
Malwarebytes, Defender is a better option while using OBS.
Game Bar/DVR are still enabled
Sample rate mismatch
Remove the User Option on the 1080p encode.
Crash Sentinel, what's that doing?

I would run the main monitor @ 120HZ & all others @ 60HZ. 165, 144 aren't helping your cause.
