Never could quite google the answer to the amount of cpu usage when software decoding HEVC. I got a free i7-4970k (non overclocked so 4ghz + boost) from brother-in-law, so now I could see for myself. For 2160p24, which means about 1600p in this specific case, I get a reported usage of about 25%. At least for the short sample I played.
