Render Lag

Ok so I know the subject has come up a lot, I have checked a lot of the threads and cant get a full fix for my issue.
So I understand that it happens when there is not enough GPU time left for OBS to render the scenes, I tried the run as admin fix and it seemed to work mostly in Pubg, I tried to stream Jedi Fallen Order and I get lag regardless, the odd thing is I tested it with a bandwidth test stream and it was fine.
Dropping the FPS to 60 so that there is free GPU time fixes the problem.

So is there any full-on fix yet? I don't want to have to put together a second PC just to stream when this PC is more than capable, I also see streamers run from one PC at high FPS fine (Halifax for example).

I play a lot of FPS at high refresh so capping the framerate isn't an option, I can't believe that there isn't a way for OBS to take priority over the game for GPU time?

Has anyone here had success streaming high frame rate games on one PC?

It's hard to tell without a log so please don't take this the wrong way. Don't render frames you can't see. If you have a 240 Hz monitor, then cap it at 240 FPS. 60 Hz, then cap at 60 FPS. You can use those resources for other things and/or better quality frames for those that you can see.

Its a 165ghz screen capped at 165hz, Pubg runs at between 120 fps and 165fps no render lag, Star Wars runs around 90 - 120 fps lots of render lag, as I say I have seen streamers run uncapped frames for lower input lag with no visible render lag on the screen.

Just had a look for the log files I seem to have 4 files modified on the 20th and 6 on the 21st, no logs before that which is odd so I don't have the logs for the Pubg stream.
What should I be looking for in the logs, it will say render lag but is there something there that will indicate why other than not enough GPU resource?

One thing I did notice was that if I alt-tabbed out the rendering lag stopped, the game was still full screen on the main screen though and still consuming the same 90% of the GPU time according to task manager, tabbing back in causes the lag to re appear
