How would an optional, official parser be toxic?

I’ve played on a laptop for almost 2 years; it doesn’t overheat. Granted, I use an additional cooling fan for it, but even before I bought that I never suffered from problems with it overheating, and I can game on it all day with zero performance loss. I fight more with my internet than I do with my actual laptop; it works quite nicely until I can build myself a proper rig.

How do you know if it's your computer or the internet that is the problem? I always see myself dodging mechs but still get hit so there must be a delay and unsure if its my computer or the net.
