Hey so the topic pretty much covers my issue. I'm using a Logitech c920 and it worked perfectly with no problems whatsoever. once I updated bandicam it started to lag extremely heavily unless i put it into a really low resolution (650x480ish) it used to work at max res (1920x1080) with no lag. Works perfectly normally with other apps. Also when I go into the overlay webcam setting where the chroma key option is, it shows my webcam with no issue, just when I record or on the HDMI output
Thanks
