No, it's not possible.
NTR is already doing unstable stuff, like using kernel mode and making multiple copies of itself in various processes (like some sort of resident malware).
HzMod can't be optimized more without defeating its original purpose.
Also, a few notes:
- not all devs moved to the Switch
- those max FPS values are theoretical, and require a very specific result, and a compressor-specific "optimized pattern" (like a full-black or full-white screen)
- you won't make any dev update their software with that attitude
- you'd get better image quality at the same FPS your tripod is recording at
Edit: fine, I give in that HzScreen is slower than SnickerStream, but if I were to rewrite HzScreen it would be EVEN SLOWER, and the game would be conpletely unplayable, as you would be recording duplicate frames.
I actually have a modified HzNod somewhere, but the FPS increase is minimal (0.5FPS average is nothing), and it's so unstable that I never released it. I should edit the main post to reflect that.
The thing to learn here is that you can't beat a snail to run faster unless you overclock it, but it might explode and turn into charcoal.
