Question / Help OBS is huge ressource hog at DirectShow Capture

Like mentioned in my VisionSC-DP2 blackscreen thread I'd like to mention another problem which I noticed with my previous Card - the Vision DVI-DL by Datapath where OBS could capture it:

(apparently) the preview takes way too much ressources while just displaying it and deactivating the preview doesnt free up its used ressources apparently. It takes ridiculous 12 to 20% GPU and 7% CPU just by OBS running which results in F1 2016 dropping from 80 to 50fps just by OBS running in the background without capture, while Virtualdub loses not a single fps even with capture!!
But I slightly feel the stress of CPU Capture on 2560x1600p60 with the MagicYUV codec plus Virtualdub does only support just 1 audiotrack and not global hotkeys which really wants me to use OBS! There I could use NVEnc with CQP 5 or even lossless but without that CPU usage.
But the advantage of NVEnc is completely obsolete if the damn preview reduces the game by 30fps while Virtualdub doesnt..

Beside of this problem I'm so happy with OBS, but this makes it unusable for me :(
