Issues fixed[edit]

Game running too fast/slow[edit]

Running too fast[2]
Cossacks: Back to War features a unique engine timing system. While the games' speed is still dependant on the CPU clock, like many older titles, they offer a flexible speed setting in the options menu to enable the user to tweak the speed to his liking.
To make the game more bearable, make sure to:
  • Go to the game settings.
  • Choose "Slow Mode"
  • Decrease the "Game speed" by approximately 10%.
  • Save the settings and go play the game.
If the game is still fast, grab ACClock or CPUGrab.[3][4] If the game reverts back to fast mode, press CTRL+D in-game.
Alternatively, use Cossacks Revamp 2017

Multiplayer Alternative[edit]

Alternative Solution to Multiplayer[5]
Whilst Game-spy is no longer available for the game, a community made server alternative for the server option is available.
  1. Go to
  2. Follow instructions depending on what version of the game you have
Steam Version
  1. Download from
  2. Extract the zip file to <path-to-game>\bin
Other Version
  1. Open the file <path-to-game>\bin\internet\ggwdc.ini with a text editor. I recommend Notepad++.
  2. Comment out the ggwdserver_addr line in the file by placing a '#' hash in front of it.
  3. Underneath the line you just commented out, add the line ggwdserver_addr
  4. Save the edited file and launch Cossacks: Back to War, use the ' Internet Game' option in the multiplayer menu and enter a username.

Crashing when changing game speed/scroll speed[edit]

Fix Crashing when changing game speed / scroll speed in multiplayer
  1. Go to <path-to-game> and find dmcr.exe
  2. Right click dmcr.exe and click Properties > Compatibility
  3. Check the 'Run this program in compatibility mode for:' option and select 'Windows XP (Service Pack 2)' in the drop down.
