My fps are dropping like craaazy in this map. It looks pretty nice thought!

There should be at least a folder cache and a folder config
in ...\Documents\My Games\KillingFloor2\KFGame
otherwise you are checking in the wrong directory.
Even without workshop items (=cache) the game wont start without the config.ini's

I don't see a cache folder in my directory.

It's in your documents: :\Users\...\Documents\My Games\KillingFloor2\KFGame
The Cache folder would be the easiest thing to delete... and it could fix it.
But the start of kf2 first time after deleting the cache take a bit longer than usual.

The ini file which could be unlikely reason is
...:\Users\...\Documents\My Games\KillingFloor2\KFGame\Config
KFGame.ini
But if you have never done anything to it, i would try the cache delete first.

Where do I find the .ini file to modify it?

Is this happening only with this map?
Maybe the reason is the preview picture, if your .ini file is set to read only.
You could try to delete your Kf2 cache, that could work

Game crashes when I highlight this map in the menu.

fps NO

nice map

The performance is in multiplayer pretty equal. Main problem for the fps is the large forest with dynamic shadows. I will add a cave to block the visibility in the center. This will boost the performance and zed spawn rate either.
Thanks for checking 🙂

Fresh Good map.
However, the frame drop is severe.
I tested it as a single, it fell below 60 fps (I often keep 144 official maps)
It will probably get worse at 6p.

I tested it a few times on a mulitplayer server and i didnt notice it so far.
I just used nodes which are also part of official maps so it would suprise me... but its not impossible.
It would be nice if you could check again and write as soon as your are sure. Thanks :)

It's gonna de-rank server, isn't it?
