So basically I have two PC's; one of them has a GTX 1060 and the other one has a GTX 760. The 760 lists every format for HEVC except NVENC, but my 1060 doesn't have this problem. I have tried reinstalling Vegas Pro, but without any success. Here is a photo of what it looks like:
Thanks! I really don't know why I didn't check the requirements for NVENC before making this post. But anyways I'm looking to upgrade to an RTX 2080 pretty soon so yeah.
