I'm using a newly acquired 3070 with a pretty high tier rig (ryzen 7 3700x, 16go 3666MHz and a good mobo) with only one 1440p 144Hz screen using Displayport other than my headset. I'm using the Valve Index with the stock cable, I don't know his rating.
In streaming, everytime I try to use h265, even h265 60fps, the player load for 1 to 10 secondes, then go back to h264, whatever I try.
I tryed the SLR app and DeoVR player, same result.
And about Viewport, I'm not sure how to test that with the Valve Index, isn't it for mobile headsets ?
PS : Sorry for my potentially ankward english. Baguette grenouille here
