If the game doesn't start at all or it's crashing, then please generate a debug log file and upload it. If the game is stuttering on a Freesync/G-Sync monitor then try to set minfps=-1. If videos or other UI elements are invisible then try to set nonexclusive=true. If windowed mode or upscaling are not working properly then try to set hook=2 and renderer=gdi. If the game is running too fast then try to set maxgameticks=60 - If it's still too fast, try a lower value.

If there are problems on Alt+Tab then try to set noactivateapp=true - If it still doesn't work also try renderer=opengl or renderer=gdi. Some games may require additional steps before they can be used with cnc-ddraw, please check the wiki for more details. Usually you can tell by the look of the game if it's a 3D game or not, but you can also let cnc-ddraw generate a debug log and search for "IDirect3D" - Link: #44 Alternatively you can also open ddraw.ini with notepad and modify the Compatibility settings in there.Ĭnc-ddraw does not support Direct3D/Glide, it will only work with games that use a DirectDraw (Software) renderer. If the game starts but it doesn't work perfectly then open the config program and check the Compatibility settings. If you want to play in windowed mode then start the game once in fullscreen and then press Alt+Enter to enable the cnc-ddraw windowed mode (Or enable windowed mode in the config program without using Alt+Enter). If you use cnc-ddraw with a game that got its own windowed mode built in then make sure you disable the games own windowed mode first. Wine (Linux/macOS) only: override ddraw in winecfg

Cnc-ddraw can fix compatibility issues in older games, such as black screen, bad performance, crashes or defective Alt+Tab.
