Vidcoder is having high CPU after buying a new RTX 4090
Problem Description
I used to have a RTX 2080 and encoding was fine using H265 NvEnc. CPU usage was around 15% or so
I recently bought a RTX 4090 and notice very high CPU usage like below (Ryzen 3950x)
So, I try another encoder called MediaCoder using same setting and encode with H265 NvEnc. CPU stay at around 15% as I expected
I wonder why such a high CPU usage after I use the new RTX 4090?
What version of VidCoder are you running?
9.9 beta
