This is a patch that will allow you to run the game at any resolution you can imagine, even custom ones.
Arcanum High Resolution Patch is an extensive engine hack and probably the most complex mod I've done up to this point. It rewrites many subroutines to make the engine fully scalable to any resolution, and calculates positions of all elements of the interface (well over 1000 offsets) for the desired width and height by using formulas. Additionally, it adjusts sound positioning, fixes a number of UI bugs and disables sprite mirroring (if used without the UAP).
* Full support for any resolution.
* All elements of the interface perfectly centered.
* All elements of the interface remain their original size with no custom graphics in any resolution.
* Full compatibility with any mods that are based off the 18.104.22.168 version.
* Full compatibility with older save games.
* Improved Compact UI. Can now be accessed anytime by pressing F10.
* Optional larger dialog and logbook fonts.
The patch runs on WeiDU, as it includes a rather flexible binary patcher with support for formulas. Qwinn's search and replace macro is also used.
The project took me many weeks of heavy reverse-engineering and debugging, as I had to go through the whole interface and many other functions to properly adapt the game for higher resolutions and make the engine fully scalable. I tried my best to keep everything as close to original as possible. Thus, the patch features no heavy UI changes, no custom graphics and no upscaling/stretching.
I'd also like to note that unlike the UAP, this isn't a community project, but rather something I've done for my own amusement. Ergo, the community feedback won't have much impact on the project, if any.
Arcanum.exe version 22.214.171.124 (English) required. Any modifications of it (this includes the UAP) will also work. Only Arcanum.exe matters, the patch doesn't modify any of your other files.
Note: A lot of data in German and French versions is shifted, most probably due to a different copy protection used. However, the English Arcanum.exe should work properly with the foreign versions, provided you can deal with its copy protection one way or another.
Any resolution is possible, if it isn't smaller than the original 800x600. Even non-standard resolutions like, e.g. 1333x789 will work, if the game is run in a window or your video card supports custom resolutions.
Note: If you have the UAP installed you can run the game in a window by using the '-window' command line argument. Otherwise, you will have to use D3DWindower or similar software.
Fully compatible with any mods that use Arcanum.exe version 126.96.36.199 (English), clean or modified.
Fully compatible with older save games. You can change resolution as many times as you want, without starting a new game.
Run the installer and follow the on-screen instructions. The installer doesn't auto detect your Arcanum folder, please be careful.
Changing to another resolution/Uninstalling:
Go to your Arcanum folder and run HighRes.bat (do NOT run Setup-HighRes.exe directly, it won't work).
When upgrading to a new version of the high resolution patch or the UAP please uninstall the current version of the high resolution patch by running HighRes.bat.
Some important peculiarities of the high resolution patch are listed here.
The patch adjusts scrolling distance according to the resolution, so that you won't be able to scroll farther than at the original 800x600. At very high resolutions (and especially with low PE) this results in scrolling distance of 1, i.e. you can barely scroll the screen if your character is already in the center (the screen becomes more scrollable as you move closer to the edges). This seems logical, since as everything is already visible, there's no need to scroll. However, if you don't like this adjustment you can run the game with the '-scrolldist:0' command line argument, this will give you infinite scrolling distance, regardless of the resolution and your character's PE. Although it's important to note that if you scroll far enough at very high resolutions you will see inactive objects.
Everything that is 31 tiles away from the PC is inactive, i.e. AI, animation, scripts, etc don't work that far away from the player, so the objects just get frozen. At extremely high (like 2600x1900) resolutions (or with the infinite scrolling option) it may be possible to see such objects. The active radius may be increased later, if there's a demand for such resolutions, although it will have a severe impact on performance, of course.
The top and bottom in-game UI panels are now visible in the main menu, since the background is too small to cover them. Perhaps a black backdrop will be added in the future to hide them.
Some multiplayer menus may not work correctly, as this is hard to test. Splash screens aren't centered horizontally yet as well.
