OK I'm going to attempt to sound like an expert, please correct me if I'm wrong.
Well obviously, hosting a server for 18 people on your own computer is going to be a nightmare. Especially the large number of zombies that have to be "synced???". Have you tried the map with normal settings i.e. 6 players? How does that perform on your computer?
it is not a disaster, at least not me (no lagging, smooth as usual), if you just compare 6 people with 18 people
The point is I played this on beta1, nobody said lagging or anything but people say lagging (or changing map due to lag issues) after your beta2, is that a coincidence?? When we play other maps, we don't have this issues, even 18 people on a large map
ZING! 18 player server? No wonder you lag...even more so with you hosting and playing on the same PC? Yikes.
It is just KF, not some RPGs, my setting works (I mean performance) just fine as usual. Even 18 people are on a server, no one feel lag at all on other maps (the size is bigger than this map), it just happen on this map.
When I am saying the lag issues, I mean just a small lagging (I mean the first wave) but it disappears. However, even my lag issue is gone, people still feel lag on this map instead of other large maps. I don't think the problem comes from my computer.
I am just reflecting what the reality is (what they complaint about and I think optimizing the map when you update new area or stuffs) and the lag issues doesn't bother me because I can play as usual and normal, my computer spec. is not the problem because I am definitely sure about no lagging issues on other large maps. It just happen on this map. I am not blaming anyone, I am just reporting what the players' complaint about.
You can just ignore it but I think this is a excellent map. However, the lag issues cause them willing to change another map instead of this. I feel pity and awful about that. In fact, this is a masterpiece because the models and style, paths, just exactly the same as shaun of the dead, even the feeling. I am still hoping your next update of this masterpiece.
In fact, the lag issues doesn't bother me after all, I will still support for this map but it sucks that some players are lagging on this map.
4X of zombie at once works just fine at the large map without any lagging
