Unreal engine Direct3D 10 renderer
Found a glitch or encountering errors? Please contact me about it!
This Direct3D 10 renderer for Unreal, Unreal Tournament, Deus Ex and Rune aims to provide a good, consistent looking and future proof renderer for these games. The focus is not on fancy effects; the idea is to have something that will allow these games to perform well and look good on modern systems, something which I can support and bugfix.
Written from scratch, it ditches a lot of legacy stuff and profits from the fact that D3D10 support means a clear baseline.
Furthermore, source code and documentation are provided (see page 2), which should aid future efforts to keep these games running.
Thanks, for various reasons, go out to Danny, Tyler, Ro, Sebastian. Special thanks to Chris who made the other renderers and provided valuable feedback.
Downloads
The renderer requires Windows Vista or later; it works fine on DirectX 11 systems.

Features
* Complete. Implements the full range of Unreal graphics functionality such as reflective surfaces, detail textures, fog.
* Support for S3TC (i.e. compressed) textures, such as those from Unreal Tournament CD 2 or New Vision.
* Consistent. Looks good whether full screen or windowed, on whatever graphics card's being used. No washed out or dark graphics. Screenshots look like they do in-game.
* Niceties: supports various quality improvements such as anti aliasing and anisotropic filtering, see below.
* Always runs in 32 bit color mode, always has all game detail settings enabled.
* Fixes various graphics glitches present in other renderers (shimmering surfaces, etc.).
* Forces the game to run on one processor(core).
* Deus Ex, Unreal: instead of the 16 lowest, the 16 highest supported resolutions are shown in the video settings dialog.
* Inreased depth precision (before after).
* Automatically adjusts field of view to aspect ratio (example).
* Override textures: textures can be replaced by external .dds files not burdened by the engine's limitations. Artist info.
* Bump mapping: can be used when a normal map texture is provided.
* Parallax occusion mapping: either the standard detail textures or an external height map can be used for parallax occlusion mapping.
* For more information on the various settings, see below.
Supported games:
* Unreal (Gold). Tested with Unreal 226final and Steam version of Unreal Gold (226).
* Unreal Tournament. Tested with Steam version (436).
* Deus Ex. Tested with Steam version (1.112fm). The most well-tested of the games.
* Rune. Tested with Rune 1.07 and Halls of Valhalla 1.07 and 1.08.
There are also renderers for some specific, non-newest, game versions:
* Rune 1.00. Offered by request. Tested with Rune 1.00.
Unreal note: The renderer does not work with the version 227 fanpatch, there's nothing I can do about this until headers for it become available. Perhaps the developers of the patch will see fit to include the D3D10 renderer at some point in the future.
Tactical Ops: Mikhail informs me the UT renderer sort-of works with 'Tactical Ops: Assault on Terror': the brightness is off and in-hand weapon models aren't drawn.
Installation and settings
1. Make sure you've got the latest DirectX update. As of writing, that can be found here. Mirror: my site.
This is critical, just having DirectX 10 or 11 isn't enough; they get updated every now and then.
Without this, the game will complain about d3dx10 files missing or otherwise crash.
2. Make sure your game is patched up to one of the supported versions, it will crash otherwise.
3. Download the renderer from the link at the top of the page.
4. Unzip the files for the game you're playing to that game's 'system' directory (e.g. "c:deusexsystem"). Note that the files (d3d10drv.dll, etc) and the 'd3d10drv' subdirectory must be directly in the system directory; make sure not to accidentally keep them in the folder they came in in the zip (e.g. 'deusex' or 'unreal_226_gold').
5. Start the game, go into its video options, and click the the renderer selection button. The game should restart and allow the Direct3D 10 renderer to be picked (make sure to select "Show all devices").
6. That should be all; read on for more settings.
Renderer selection window
The renderer selection window.
Note that all standard Unreal engine detail settings such as 32 bit color, coronas, detail textures etc. are always enabled no matter what the game might say.
To change the various advanced settings the renderer offers you need to conjure up the advanced preferences dialog:
* Unreal: choose 'advanced options' in the options menu.
* Unreal Gold and Unreal Tournament: choose 'tools->system console' in the main menu bar, enter "preferences" and hit enter.
* Deus Ex: while there's no menus on the screen, hit the 't' key, remove the "say" text, type "preferences" and hit enter.
* Rune: choose 'advanced options' in the 'game' options menu.

Direct3D 10 renderer settings.
The dialog shown above should pop up, browse to 'rendering->Direct3D 10 support'. The renderer offers these settings:
Anisotropy
Anisotropic filtering, makes textures look less blurry at a distance. Valid settings: 0 to 16. Default: 8.
Anti aliasing
Greatly improves visual quality by filtering jagged lines. Valid settings: depends on video card. 1 and lower is off. 16 is the absolute maximum. If an unsupported setting is selected the renderer falls back on the next lowest supported one.
LOD bias
Setting this to a negative values makes the game use larger mipmaps (textures) than it'd normally do. Theoretically improves quality but far-off textures tend to look too 'busy'. Valid settings: -10 to 10. Default: 0.
VSync
Synchronizes the game's frame redraws with monitor updates. Reduces visual tearing. More importantly, it has the effect of limiting the game's framerate to your monitor refresh rate
, which will often be around 60 times per second. Recommended to keep this enabled as it prevents the games from running too fast, which introduces various issues such as crackling sound. Valid settings: true/false. Default: true.
Precache
Makes the game preload textures, which can lead to smoother gameplay. However, it does increase (un)loadtimes. Valid settings: true/false. Default: false.
Alpha to coverage
Smoothens the edges of 'masked' textures such as grates and leaves. Unfortunately, this does lead to artifacts where the textures don't tile (example). Requires at least 4x anti aliasing enabled to take effect. Valid settings: true/false. Default: false.
Bump mapping
Attempts to fake bump mapping if textures have normal maps present (the bump mapping setting does not have to be enabled for this, but it looks best). Requires a normal map to be either present in the texture's bump map slot, or provided as an extra external texture. Valid settings: true/false. Default: false.
Parallax Occlusion Mapping (POM)
Gives surfaces 3D relief. Pretty GPU intensive, and you might not like the way it looks. Will use an external height map texture if present, otherwise the detail texture is used. Valid settings: true/false. Default: false.
Classic lighting
By default the renderer uses a more vibrant lighting method than the original games. If you don't like the way this looks, or are playing maps that suffer from blown out lighting, enable this setting to match the lighting of the original renderers. Valid settings: true/false. Default: false.
For most of these to take effect, the renderer needs to be restarted. Switching to full screen (and back again if desired) accomplishes this.

Known issues
* Performance: this renderer just plain isn't as fast as the available Direct3D 9 renderer. There's various reasons for this; but efforts are made to have it be as fast as possible, within limits. On any system with a reasonable Direct3D 10 graphics card (so no mobile Geforce 8400s) performance should not be an issue, though.
* Print Screen button does not work. Please use the game's built-in screenshot function instead (F9 for most).
* Various multi monitor + full screen mode issues, such as the secondary monitor going black or odd performance when trying to play on the secondary monitor. I've looked into this but it seems there's little I can do. If any of these issues crop up, it's best to play in a desktop-sized window.
* Need to do more playtesting, there are probably some undiscovered glitches left.
Known non-issues
Testing the renderer, some issues cropped up which were found out to actually be due to the games/API itself and visible
on all renderers tried. Some might still be able to be fixed in a renderer though. Also, be sure to check page for Deus Ex issues.
* Disappearing geometry. In some places patches of geometry can disappear, this is probably over-agressive visibility culling. Example.
* Black boxes around skybox hills when playing UT with S3TC textures. This is Pro-Ablem with these textures.
* Unreal Tournament: Muzzle flashes displacing depending on field of view.
* Deus Ex resizes the window when going into the options screen. This happens because the game switches to a listed, full-screen resolution.
* Deus Ex: flickering reflected walls in some freezers (Lucky Money club, Old China Hand).
Pre-emptive FAQ
Why Direct3D 10?
Multiple reasons. It's bound to be the most future proof; the newer the API the less problematic with modern hardware it's bound to be; it's a clear baseline from a hardware standpoint; it makes most sense for me to work with this API at this time. Some effects are plain not supported on earlier APIs, for example the geometry shader is used to calculate world geometry tangent space.
Why haven't you added fancy effects such as [effect]?
At this point, the aim is purely to have the games run and look good and glitch free; although
some nice effects might be added in the future, it's not the intent to have the games drowned in misplaced bloom.
Why doesn't the renderer support [game]?
Unfortunately, adding support for a game requires that its developers released a native modding SDK. I don't know of any games for which that applies other than the currently supported ones.
Will the renderer work with [game] anyway?
There's no harm in trying, but it will probaby not work. Perhaps one of the renderers will work with one specific version of a game. I have tried Undying, Wheel of Time, Klingon Honour Guard and DS9 The Fallen; none of them worked.
