Question / Help Game fps drops with capturing DSLR as webcam


New Member
Hey guys,
to start here are my specs:
single pc stream with i7 8700, 2070 super, 16gb ram, streaming 720p60 at 5500 bitrate.
My main game is CSGO and when i stream with normal webcam or without it I have no performance issue. But when I connect my dslr as a webcam with elgato hd 60s and I stream and play I experience fps drops and game isnt as fluent and stutters.. Since I play csgo on very competitive level, this sometimes causes me not hitting flicks and irretates me to extreme levels.
I tried to reinstall everything but still experience this. Any idea, what could help?
Thanks :)
