On your server, open up task manager and sort by CPU usage.  Start playing a video and tell me what process is using the most CPU.  I'm betting it is Windows Defender.  I had the same issue when I was still running Jellyfin on Windows.  Even with HEVC direct plays, I also had issues with responsiveness just from Windows Defender inspecting the video file.
