### Instructions
|
|
|
|
1. Download [cnc-ddraw.zip](https://github.com/FunkyFr3sh/cnc-ddraw/releases/latest/download/cnc-ddraw.zip) and extract it into your game folder
|
|
2. Start the game
|
|
|
|
Wine (Linux/macOS) only: override `ddraw` in [winecfg](https://wiki.winehq.org/Winecfg#Libraries)
|
|
|
|
|
|
|
|
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.
|
|
|
|
|
|
|
|
**cnc-ddraw does not support Direct3D/Glide**, it will only work with games that use a **DirectDraw (Software)** renderer. 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: https://github.com/FunkyFr3sh/cnc-ddraw/issues/44
|
|
|
|
|
|
|
|
Some games may require additional steps before they can be used with cnc-ddraw, please check the [wiki](https://github.com/FunkyFr3sh/cnc-ddraw/wiki) for more details.
|
|
|
|
|
|
|
|
**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 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/FunkyFr3sh/cnc-ddraw/issues/44)
