### Instructions
1. Download [cnc-ddraw.zip](https://github.com/CnCNet/cnc-ddraw/releases/latest/download/cnc-ddraw.zip) and extract it into your game folder
2. Start the game
Note: 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.
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 the game starts but it doesn't work perfectly** then open the config program and check the **Compatibility settings**. Alternatively you can also open ddraw.ini with notepad and modify the **Compatibility settings** in there.
 
**Compatibility settings in ddraw.ini**
- 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`.
- If the **game is running too fast** then try to set `maxgameticks=60` - If it's still too fast, try a lower value.
- If **windowed mode or upscaling are not working properly** then try to set `hook=2` and `renderer=gdi`.
- If **videos or other UI elements are invisible** then try to set `nonexclusive=true`.
- If some parts of the screen are **being displayed diagonally** then try to set `fixpitch=true`.
- If the game is **stuttering on a Freesync/G-Sync monitor** then try to set `minfps=-1`.
 
**If the game doesn't start at all or it's crashing**, [then please generate a debug log file and upload it.](https://github.com/CnCNet/cnc-ddraw/issues/44)
