I read that Quick Sync is much better than x264 so I decided to try it. People said that there is nearly no performance impact. But like x264 encoder, I lose half of my fps using Quick Sync. For example Paladins by Hi-rez - without OBS Studio - 60-65 fps- with OBS Studio - 25-30 fps.I want just to record without losing so much fps.

But to use Quick Sync, OBS must be run with Intel iGPU and my game works on the Nvidia one - so if I turn of multi adapter comaptibility I can have blackscreen problems.
 
Where are they? I used to use obs on the NVidia GPU but no quicksync encoder option until I switched to th iGPU.
 
Your first log doesn't show any stream or record.

Show us OBS-studio logs that shows stream/record and actively capturing the game using game capture.
 
Biggest Problem: (if game running on Nvidia graphics): it has to transfer from NVidia GPU to intel graphics not once, but twice, slowing down game. One to transfer to intel graphics where the monitor is connected, and again for OBS-studio game capture when OBS-Studio is running on intel graphics.

if OBS-studio is running on intel graphics, and game is running on NVidia graphics, monitor capture or window capture might work much better then game capture. Try starting a new scene collection with just a monitor capture.

-- OR --
You can open device manager (right click windows logo) and disable NVidia graphics in device manager (do not uninstall), to force everything to run in the same GPU (intel graphics), where game capture can use a faster shared texture mode. Do note that intel graphics cannot be disabled where monitor displays are plugged into (may cause blank screen or terrible performance).

edit:
OR, some laptops (not all) have a BIOS/motherboard settings that could run everything on NVidia graphics, including the monitors. What is your laptop model number?

But intel graphics are too slow to run my games. Can only Quick sync files run the intel graphics and other programs on Nvidia GPU.
