It's a lot less than before
17:46:01.516: Output 'adv_file_output': Number of lagged frames due to rendering lag/stalls: 462 (0.8%)
If you want you can do a Test Scene Collection. Don't worry, you old scene collection will still be under "Untitled"
Once you create the new scene collection, add a single Game Capture, nothing more.
Do some test recordings and see if you still lag close to 1% frames. If it is clear, then you know it is one of your Sources or filters that is pushing your GPU usage a little too much.
Other people will tell you to cap your FPS in game to reduce your games GPU usage, I will not tell you to do this unless you still have > 0.1% lag frames with just a Game Capture.
There are things other than GPU Usage that will cause you to lag frames, it's not strictly GPU usage
