You've been playing 1.7 for at least a month now its not even a huge change from 1.8 So ure pretty used to it
all the videos after the Panqu 4 potted video are in 1.8 the Cefu and umz2k9 1 is in 1.7, I went back 2 1.8 cuz I get shit aim on 1.7
On 1.8 there's a small mouse delay but You shouldn't recognise it since you don't to anything intense
