dgVoodoo Glide wrapper.

Both I-War and Defiance appear to work perfectly (pre-rendered in-game movies included) with v1.50 of the dgVoodoo wrapper (n.b. v1.4 had a subtle bug which causes problems with I-War in some missions).

To use this wrapper with I-War, extract/copy the following files from the dgVoodoo archive into the root game directory (whereever you installed the game to; e.g. C:\games\I-War )

* glide2x.dll
* glide2x.ovl
* dgVoodoo.vxd
* dgVoodooSetup.exe

Only these four files are needed.

Edit (10/6/2010): (To use dgVoodoo with the Defiance expansion pack, you will need to copy these files into the Defiance sub-directory, but you should wait until you have the wrapper configured and working before doing this, because configuring dgVoodoo modifies its DLL file, and you want to be copying the newly-modified and working version from your I-War directory.)

To configure the wrapper, run dgVoodooSetup.exe (the new copy in the I-War directory!), select the "Glide" tab, and under "LFB Access" select the "Closer to real hardware" checkbox. This will prevent some confusing 'ghosting' problems that can occur with the HUD in the game's full-screen (TAB) mode.

Edit (30/5/2010): Stormwatcher reports that on a Radeon HD4850-based system, enabling "Closer to real hardware" had the inverse effect, and that leaving that option disabled was necessary. I would still suggest that you try enabling the option to begin with, but do then try disabling it if you find that you encounter visual problems.

Edit (29/5/2010): With my current Radeon video card, I also needed to set the Renderer API to "Direct3D9" (under the "Global" tab) due to various visual glitches. If the default Direct3D7 doesn't work well for you, try changing this setting.

You may in addition wish to enable dgVoodoo's "windowed mode" option. This enables the entire game to run in a window, which can be invaluable if you have CTD (crash to desktop) issues with the game, as your desktop resolution and colour depth will not be affected by a CTD. To enable windowed mode, go to the "Global" tab in dgVoodooSetup, and select the "Windowed mode" checkbox.

Edit (30/5/2010): When configuring the "Full screen" screen mode in the dgVoodoo "Global" settings tab, you may also need to select "32-bit" under "Screen bit depth". Try it both ways if you have problems. If using Windowed mode, I believe dgVoodoo uses the bit-depth of your desktop (which is almost certainly 32-bit on any modern PC).

Now run the game! You can choose both the 640x480 and 800x600 Glide/3Dfx video modes, or for the best possible display quality, try setting the Resolution (under the Glide tab in dgVoodooSetup) to 1600x1200 and then using the 800x600 shortcut to run the game (if doing this in Windowed mode, you will of course also need to set a desktop resolution of at least 1600x1200!). Some aspects of the game such as the menus and the in-game HUD will still render at an effective 800x600, but as the consequent scaling is by a factor of exactly two, there are no resulting artifacts. On-screen 3D objects will benefit from the higher resolution, however! Having said that, the scaling can cause the pre-rendered video performance to suffer quite noticeably, so you may still prefer to stick to 800x600.

The game appears to run perfectly with the above settings, so I do not recommend further modifications to the default configuration. In particular, do NOT force triple buffering (under Glide - Miscellaneous) or you will likely suffer problems with the in-game movies.
