Hey, I have frame heavy drops when recording 4k videos with OBS from capture card.

When I start recording GPU Usage go from 20-30% to 92%, GPU Video Decode go from 0% to 48%, GPU Processing go from 0% to 17%.

I don't have this problem when I recording with Mirillis Action. When I start recording GPU Usage remains the same as before recording started 20-30%, GPU Video Decode go from 0% to 28%, GPU Processing is always 0%.

OBS settings:
3840x2160 / 60 FPS / QuickSync HEVC (trying also QuickSync H.264) / CBR / 50000 Kbps / TU7: Fastest
Scene: One scene with Video Capture Device and disabled preview.

Mirillis Action settings:
3840x2160 / 60 FPS / QuickSync HEVC / CBR / 50000 Kbps / Ultra quality

Thanks for any help and suggestions.
