Remember that lag doesn't take up the entirety of gameplay. Gameplay is just as much the flow of the game when you're not experiencing lag. Vareide mapmakers put time and effort into making sure gameplay runs smoothly, and the map is fun to play. Imagine SG5 without lag for a second.
It would probably be the best map so far in terms of overall gameplay, no? This is proof that Team Vareide made an amazing map with gameplay 100% in mind. Now, I'm running on a two year old Toshiba laptop, so don't think I have some high-tech gaming computer and have no idea what you're talking about, I'm just looking at all the possibilities and potential in SG5, and I'm seeing a lot.
