Another workaround came to my mind just a second ago... I have a box that handles 4k. I don't use it. I use 1080p all the time. So there should be ~3/4 of VIDEO ram available and not needed. Is it possible to tell the system not to reserve that ram for A/V usage so i would have that for streaming purposes?
I didn't do the math - it's probable it's not much...
Have a nice day everyone!
