Getting rendering lag even when no games are open.

[hasudo]

As the title says, even without any game open, OBS studio is noting Frames missed due to rendering lag.

During a test recording of FF14 Endwalker, my OBS log states my GPU is being overloaded, but according to my task manager my GPU utilization is only 20% while recording. Does anyone have any idea why this is happening?

Specs:
AMD Ryzen 7 1800x
32 GB ram
Geforce 2080TI
Game Mode on/off doesn't matter.
DVR is turned off.
OBS Studio is being run as admin.

Interestingly I had this issue on a previous PC and through trial and elimination, running either Equaliser APO (or the front-end "Peace") in the background was causing it. As soon as these were turned off in Task Manager, the rendering lag ceased completely.

I now have a new PC and sadly having to go through the same trial and elimination again....

Further to my post above, changing my FPS value in the Video settings from 60 to 30 (just for testing purposes) has dropped the rendering lag from say 1.8% average to 0.4% (or less, depending on what I also have running - eg a multi-tabbed browser).

I'm otherwise idling in OBS (no games running) with a 3080 so I'm a tad surprised there is any issue at all.

I am no OBS expert, but from my experience the issue definitely seems to be linked to background apps and OBS video settings (FPS values certainly but even dropping the base & canvas resolutions from 1440 to 1080 seemed to make a difference).
