Mostly I was arguing about their netcode; though the vis was part of it.

For about a year I was trapped on dialup. One problem I had with the netcode was I could see a delay between when I first entered a new vis section and when the entities would display. This happened on broadband, too, but if your ping is less than 40ms, there's but two or three frames to possibly notice the effect, which means you don't see it unless you ambush a broken Office window. (Indeed, I'd strafe out and for the first couple frames the window was clearly normal, then it would update and appear in the broken-out state. And this effect was repeatable by simply leaving and re-entering that vis section.) On dialup, however, your in-bound packet rate is already slow, and your ping is high, which means you're frequently mowed down by invisible men. You turn the corner in Office, see nothing but an empty hall, you notice one frame seemed to render slowly, and *pop* there are flying file cabinets and three CTs spamming and bagging your now-dead corpse. gg. So, I charged them with adjusting the code so the server would send information on entities that are in neigboring vis sections so this problem would be solved. I attribute it to the "P90" problem where a SMG rusher would seem to run at double-speed into a hallway while spamming wildly.

Anyway, I know they added some data compression to allow for faster acquisition of entity information, though I'm no longer dialup so I haven't monitored the vis section issue.

My big mistake was being honest. As soon as I said 56k I was regarded as just another brain-dead noob with lag who's money they already have and I was initially mostly ignored and sent kopipe "we can't fix your lag" and "how to tweak your modem" links until my persistance wormed its way up the ranks. If I'd lied and said I was on super duper quantum fibre optics that has 250ms lag because the wire runs up to my awesome space station, they would've given me full attention.
