Ok i checked some of your older (2018) and newer (2024) demos, and they are indeed different about strafes, meaning what you said could be the truth, i don't want to go deeper about it.
you wrote about "keykron k3" but you could also explain that it has two versions: Mechanical and Optical keys, i don't see a reason why would i needed to waste my time about, if you were directly asked about - you could explain that in one sentence, but whatever
i must say i agree that the optical keyboards can cause this problem, but also cheats can do this. so i guess you are enougly smart to understand my (i cant say for Kpoluk's side, but seems me and him are on the same boat) concerns about your case
now, the thing is, what to do with these information, should KZ communities reject all demos with optical keys ? SnapTap is everywhere disallowed, no need to discuss it.
so, what is your opinion, as clean player (lets say i trust you) and uses that optical keyboard, what should we do in future?
i had idea that every player should be having stated: "Optical keyboard" on his profile (kzrush site, cosy, xj, or whichever)...but that will open door for cheaters, who from demochecking team is willing to battle with that .. :)
other way is to totally reject players with optical, snaptap
PS: i don't think private messages are needed, lets write problems publicly, i don't see why we should hide any conversations
EDIT: if I'm not mistaken there is difference between snaptap and optical:
snaptap is doing you a favor, to not have overlapped strafes, optical is not doing that
correct me if I'm wrong :)
