frames dropped and video lag while using zoom and obs


New Member
I am a music teacher teaching online via zoom and using OBS(virtualcam). I am using OBS as virtual cam to zoom. Since past few months I am facing issue of lag in the video and lots of drops in frames. Not sure what is the issue. tried all hacks. Still not working. Day by day the the issue is getting worsen and now I teach only in zoom without obs where I dont get this issue. Please help me so that I can again use OBS with zoom.
I have original windows 10 with dell new laptop(precision 3551). RAM 32 GB, HW: 1 TB SSD, Intel i7 10 gen, graphics card: quadro p620(4 gb)
