I have a Mac Pro 3,1 that I would like to get hardware HEVC decoding working on. I have some 4k videos encoded with HEVC that do not play smoothly on my machine and max out the cpu. It seems as though the GeForce GT 1030 supports HEVC, is cheap and can be flashed to work in a Mac but im curious if anyone has any experience with this? Also I am currently running a GTX 680 4GB in this machines only PCIe x16 slot. So I would be putting the GT 1030 in a x4 slot. I currently run a 2nd gpu (gt 120) to my tv on a x4 slot and it works fine (just no 4k hevc). Sooo if anyone has any insight as to if this would work I would appreciate the info! Btw the GT 1030 would only be used to play video on my tv. All other gpu related tasks i use my gtx 680. Thanks!
