It's bad enough that I lag with crappy Australian internet to other people, but V5 taking up a ton of CPU locally makes it nearly unbarable to play just about any server, for me... Because of my internet lag, before people were just randomly 3 or so steps ahead of where they really appeared on my screen, but now with CPU crap, I might as well just stand still and watch people warp around me.
and it get's so bad to the point that Graal will totally freeze at time for up to around 2 minutes.
