Clowe.source Make sure you're playing in borderless windowed, not fullscreen.
Also try updating your GPU drivers and reading the low FPS guide
Last thing what's your antivirus software?

With JezuzLizard's guidance I was able to get this working. Steps are:

Open the map's IWD as an archive
Navigate to ui -> modname.menu
Find the dvar name you are trying to change based on some string or by brute force (I recommend Notepad++'s find in files function)
Add set [dvarname] ["value"] to server_zm.cfg
Run

Tadaa

firesgtent said in Servers in WAW (Game Over issue):

o start the game

this only starts the game for the person who used the command in solo.
I used to think this also fixed it

The settings are saved in DVars, so you need to set these in the batch when launching your dedicated server.

gamemode_index 0-2 (Normal, One Room, Gun Game) bossZombie 0-1 difficulty 0-1 (Original, Easy) timedGameplay 0-1 startingRound 1, 5, 10, 15, 20 (only when timed gameplay is off)

it requires a webserver and or wamp setup in order to use fast dl properly

pretty much like this
but of course adapt it for waw but as stated you either need a webserver or have a proper setup of wamp

@lResxt I've tried automating switching, but the game doesn't have any reliable way of shutting the server down after a game over atleast to my knowledge
