Thanks again, thats much better indeed. Your extra parameters made me look into them for research. Normally, I never like filters and prefer raw process(I also dont like anti-aliasing in games or extra bass/treble adjustments in music so I am this type of guy), but this depend on person and I think some of your parameters provide good results without overdoing things. Lets get through them 1 by 1 for others to learn:
-nosub, I believe this disable subtitles, this have nothing to do with games and if does should probably be avoided
-unsharp, here is nice video showing its effect(I dont know why it mangle youtube links, you need to replace bad characters or search the final string):
w w w(dot)y o u t u b e (dot) c o m / ?v=QbaPLEcTR1k
Since you only use very mild 0.7, this should provide nice results without worsening image. I will definitely try it next time.
-for audio output, you should use default game's codec which is most of the time AAC or ogg, which are way better than "lame". More important, with those you can go to low 64k bitrate with almost no noticeable difference to further save space:
w w w(dot)y o u t u b e (dot) c o m / ?v=xbw3ItwCrv8
-subq, this is like optimization to speedup process at the cost of quality(read about it here:
https://sites.google.com/site/linuxe...ffmpeg-mapping).
This could be handy for CPU encoding, your value "4" is lower than default 6 which provide better quality. I havent seen difference personally but it is worth trying to save time on CPU encoding. For nvenc its not needed IMO to compromise quality because HW encoding is already extremely quick.
-bframes, this option dictate compression efficiency and speed especially with some other options together(vis. link above again for reference and also this:

For HW enc. again I see no importance, default should be better but for CPU maybe, however if it is like anything similar to "p" option on bink, on that one setting to its maximum "64" had no speed difference on my computer and max = best quality, so I am not sure about this one.
