Quote from Trigger;22275:
I've left my PC on for longer than that with quite literally no side effects, running high-end FPS games on Steam at max framerate even at the end of those periods.
Idling on TF2 does not count.
TF2 is not a high end game either, it's old. The STEAM engine is made to work with old, low end computers. It's not any special that you're having that engine on running for weeks.
Besides, who knows how much crap those servers can process.
And remember, this is NEXON's servers, not your computer. You expect them to buy you shiny new top tier servers, or old re-used and broken ones?
