So, are there only two types of PC gamers, r0ach? Ultra-casual peasants whose opinion on anything and everything should be instantly disregarded and real competitive pro-gamers who run "properly tuned" Windows 7 Ivy Bridge systems without "clown cursor" which allows them to pwn noobz at the peak efficiency (presumably around Gold Nova rank)? There are only those two options, nothing else?
Anecdotally, BTW, a good friend of mine played CS at Global Elite level and later went semi-pro via FaceIT. He knew exactly jack and sh*t about PCs. The guy had to call me up when he wanted to reinstall an OS a couple of times, for Pete's sake. He definitely ran no "advanced tweaks". He did have a 240Hz monitor and he did run FreeSync on it. That, weirdly enough, did not stop him from being insanely good at the game. Funny that.
Oh, and I am sure that numerous actual testing done that proves that VRR with a proper frame-cap has no actual negative input effect should also be disregarded as fake and false? Again, when are you going to actually, for the first time in a decade, put your money where your mouth is, acquire an LDAT kit and prove, once and for all, that your way is the way?
