I was able to successfully get my TV to switch over to HDR mode last night in Win 7 using MPC-HC + LAV + HDR passthrough but it was so laggy. I checked my CPU usage and it was spiking up to 100%, whereas my GTX 1060 3GB was only hitting 30-40%, this doesn't seem right to me. Any thoughts on this ?
Also, for anybody who may know this answer, what windows resolution, refresh rate, bit depth and color range (full or limited) should I be using on my windows desktop ? On my OLED B6 I can set it to 24Hz 12 bit Full at 4K resolution - but when in 60Hz mode it only lets me choose 8 bit.
