OBS Running GPU high after Clean Drivers install. - Games running normal before, Now it's not with OBS

Hello people

I have been playing around as I had some GPU issues in the last two days and impaired performance in games and I have resolved it. From clean drivers installed and other improvements. However, OBS is now back to where it eats up my GPU and Microsoft flight sim becomes stuttering while streaming.
  • So I have MSFS locked at 31fps on medium and while nothing running she's only using the maximum GPU of around 75% to 85%
  • When OBS is running and not streaming she jumps up to 85% to 95% - depending on what I'm doing in the sim.
  • As soon as I stream using my GPU to encode, OBS jumps up another 10% to 20% and MSFS FPS goes from 31FPS down to 20FPS
  • From the task manager, OBS is using around 30% to 35% while streaming.
  • Before I had a GPU issue I always had the same settings and streaming and MSFS together I always has 30FPS and so why NOW..?
  • I decided to test stream using my CPU to encode and that's all fine while still having 30FPS using OBS to do CPU
Running i7-10700k @5.1 with 32GB memory and 1660Ti

Yes, I do not run everything high, like I said GPU runs around 60% when not streaming with everything off. I do not want to turn game settings even lower as it was going all fine up until I had to remove the GPU to get to the M.2 drive slot and now OBS is running higher than before.

Another thing is also why I keep dropping frames (network) yet I have super-speed internet and it's stable and OBS thinks otherwise
