D2DX is a Glide-wrapper and mod that makes the classic Diablo II/LoD run well on modern PCs, while honoring the original look and feel of the game. Play in a window or in fullscreen, glitch-free, with or without enhancements like widescreen, true high framerate and anti-aliasing.
- Turns the game into a well behaved DirectX 11 title on Windows 10 (also 7, 8 and 8.1).
- High quality scaling to fit modern screen sizes, including widescreen aspect ratios.
- High FPS mod using motion smoothing, bypassing the internal 25 fps limit. Play at 60 fps and higher! (video)
- Anti-aliasing of specific jagged edges in the game (sprites, walls, some floors).
- Seamless windowed/fullscreen switching with (ALT-Enter).
- Improved fullscreen: instant ALT-TAB and low latency.
- Improved windowed mode.
- Proper gamma/contrast.
- Fixes a few window-related glitches in Diablo II itself.
FPS increase in menus, FPS increase for projectiles, monsters, +more
- Windows 7 SP1 and above (10 recommended for latency improvements).
- A CPU with SSE4 support.
- Integrated graphics or discrete GPU with DirectX 10.1 support.
Basic rendering is supported for all Diablo II versions and should work for all mods.
High resolution is provided by SGD2FreeRes and supports the following versions: 1.09d, 1.10, 1.12, 1.13c, 1.13d, 1.14c, 1.14d.
The anti-aliasing filter is supported on all LoD versions except: 1.09c, 1.13a and 1.13b.
High FPS and motion smoothing is provided by D2fps and supports nearly all released Diablo II versions. This may have compatibility issues with other mods providing the same features.
MedianXL is not compatible with the resolution mod. Launch with -dxnoresmod or set noresmod=false in d2dx.cfg.
Auto casting can sometimes get stuck when the game fps is unlocked via d2fps. Can be worked around by setting the fps to a number higher than can be rendered via d2fps.ini (e.g. 10000). Vsync can still be used to limit the frame rate via d2dx.cfg.
For compatibility with other mods, see the wiki.
This readme contains basic information to get you started. See the D2DX wiki for more documentation.
Copy the included "glide3x.dll" and "d2fps.dll" into your Diablo II folder.
Note that in some cases you may have to also download and install the Visual C++ runtime library from Microsoft: https://aka.ms/vs/16/release/vc_redist.x86.exe
To start the game with D2DX the game will have to be launched in glide mode. This can be done by:
- Launching the game with
-3dfx. e.g.game.exe -3dfx. - Selecting '3dfx Glide' from
D2VidTst.exe - Setting
HKEY_CURRENT_USER\SOFTWARE\Blizzard Entertainment\Diablo II\VideoConfigto3in the registry
Windowed/fullscreen mode can be switched at any time by pressing ALT-Enter. The normal -w command-line option works too.
Many of the default settings of D2DX can be changed. For a full list of command-line options and how to use a configuration file, see the wiki.
You are running the download version of Diablo II from blizzard.com. This can be modified to work with D2DX (Wiki page about this to come).
Let me know by filing an issue! I'd like to keep improving D2DX (within the scope of the project).
