Didn't have any terminal tweaks unfortunately, performance seems slightly better but I have a fairly old box a 409 so not sure how much to expect really. MKV playback still pegs the CPU at 100% and causes pausing playback. But converted to mp4 it plays fine even the same size file. Some say it might be an interlaced audio issue but no idea, probably best to get a new one or ditch it altogether for a home build.
