WaltherClassico: Hi guys.
I have Win10 64bit installed and the game actually does function as installed without any special actions needed. Just launch the game from the "gangsters.exe" file in the game directory (usually found under c:\GOG Games\Gangsters\).

However I did experience some lag/delay issues to which I found a 'partial' fix for on this forum (Thanks to user Treatid):
1) Run regedit.exe
2) Go to HKEY_LOCAL_MACHINE/SOFTWARE/Microsoft/Windows NT/CurrentVersion/AppCompatFlags/Layers
3) You should see an entry for Gangster.exe. Double click it to edit it.
4) Replace the entry currently in it with
"$ DWM8And16BitMitigation 8And16BitTimedPriSync 8And16BitAggregateBlts Layer_ForceDirectDrawEmulation"
(remove the quotes)

(Original thread: "does_not_work_in_windows_8")

The Menu's are still not visible. But alt-tabbing out of the game will make the text show (may crash computer though, so write it down).

So far so good..

I NEED HELP THOUGH. I wrote 'partial' fix to the delay issue because I am still experiencing delay whenever the map (roof top) view is displayed when giving orders and when in working week - no difference. Its frustrating and unfortunately it gets worse during the game.

Any one know how to fix this?

I tried:
* Disabling Vertical Sync in Geforce GTX 560
* Disabling mouse precision
* Disabling/reducing administrator rights
* Kill-explorer "fix" (fyi. not needed with the above regedit fix)

I hope someone can help :)

Best regards,
Walther
