Hm, i have just realized a thing. Sitting here testing various computers at my university library i have noticed that some sequences of keys being pressed on certain computers happen to show the very same problematic behaviour i have at home, where i every now and then get the key sequences "ds" and "cs" when i intended to hit "sd" and "sc" (trying to hit the latter letter really fast after the first one), caused by what i initially thought was my human error alone. For example at the computer im sitting at right now, some old (but not ancient) Dell with some generitc Dell keyboard. Whenever i try to hit the two buttons "y" and "u" at the same time on this Dell computer they always show up as "uy" on the screen, and they surprisingly do so even when i really try to make sure that "y" is being pressed just a tiny amount of time ahead of "u". I have spammed this for a good 5 minutes now (trying to hit the two keys at the very same time or trying to hit the "y" key just a tiny amount of time ahead of "u") and i see "uy" on the screen every single time. Surely there must be something to this seing as i did not get "yu" a single time during my spamming.
So after seing this im starting to think that i must have the same issue to some degree with certain key sequences at home, and that there must be more than human error to it. Im using a high end system at home and ive had it for about 1 year now: Asus p8z77-v, 2700K, gtx 580, 16 gb ram, windows 7 64 bit, etc. The keyboard im using is also a pretty high end one: Zowie Celeritas MX red (has full NKRO via ps/2).
So im wondering, is this in fact a thing? That certain keys on certain systems for various reasons can register at different speeds meaning that two keys being pressed almost at the very same time always will show one key ahead of the other one? If so, does it solely have to do with the keyboad or can it also depend on the motherboard or something else?
Someone please enlighten me.
I could imagine that this in fact is a thing but that most users would never even notice it, but since i play SC2 where i play Zerg and make a ton of units during a typical macro game, through "evolution" in my game i have always made units faster and faster, meaning i hit certain key sequences faster and faster. So when i play the game now and make units without "thinking" about it and just let my hands do what i use to do when i make units i keep getting this issue every now and then for certain key sequences.
