- (1) SYSTEM REQUIREMENTS
- -----------------------
- OS: Windows 95/98/2000/ME/NT4
- CPU: 200 MHz
- RAM: 32 MB
- Disk Space: 235 MB
-
- Windows NT4 users must have service pack 4 or higher installed.
-
- You must have Direct X 7 or 8 installed on your computer (Direct X 3 is
- acceptable for Window NT 4 users). To preserve space, this demo does not include
- Direct X - most people already have it installed. If you do not have it, it can
- be downloaded from www.microsoft.com/DirectX
-
-
- -----------------------
- (2) PLAYING THE DEMO
- -----------------------
- The demo is fairly self-explanatory. Launch it, and you'll be at the main menu, where
- you'll be given a bit of overall information about the demo. After going through
- this, select 'Tutorial', and you'll be taken through Tropico's interactive tutorial.
- When you've finished, you can continue playing the tutorial for 50 years, as a normal
- scenario.
-
- For further information, the full manual for Tropico has been included with the demo
- and is accessible through the 'Start - Tropico Demo' shortcut group.
-
-
- -----------------------
- (3) TROUBLESHOOTING
- -----------------------
- A) Performance
- The two most important factors in determining how smoothly Tropico plays are your
- CPU speed and RAM. Tropico is playable with the minimum specifications listed above,
- but plays more smoothly the faster your machine is and the faster your CPU is. In
- general, Tropico detects your machines specifications and adjusts certain game
- parameters accordingly. If you wish to tweak things yourself, bring up the settings
- window (press <F2> in the game world).
-
- If your CPU is slow, try turning down the options in the 'graphics' tab. Turn trees to
- stump only mode by pressing the <T> key. Turn off weather animation by pressing <W>.
- Don't turn the game speed above 'Normal' late in the game, with lots of people moving
- about (nothing especially bad happens, but running the game very fast with lots of
- people increases choppiness.
-
- If you only have 32MB of RAM, go into the 'memory' tab in the settings window and uncheck
- all the options, and turn max detail to the first or second setting. Avoid rotating
- the map (which loads more graphics, using more RAM). If you have more than 32MB of RAM,
- it's still not necessarily a good idea to turn all the memory options up - things may
- run smoothly early in the game, but slow down later on when more people and buildings
- are on the map. Typically, the default settings determined by the game for your system
- work best, over the course of a full game.
-
- Also, you are strongly encouraged to shut down other applications before launching Tropico -
- other applications can drain resources and slow the overall system down.
-
-
- B) Crashes involving screen-savers, automatic power-downs, task switching.
- Crashes can sometimes result when:
-
- i. A screen-saver saver kicks in
- ii. When your system automatically powers-down after a period of
- inactivity (as some newer computers are automatically set to do)
- iii. When you task-switch to other applications (by clicking on them on your
- Windows taskbar or by pressing alt-tab.)
-
- In general, Tropico can handle all of the above properly if it is running in
- software 3D mode, but, depending on your video card, can crash or hang if you attempt
- any of the above while running in hardware 3D mode. You are encouraged to either avoid
- the above activities (by disabling your screen-saver and/or auto power-down, if necessary),
- or to run Tropico in software 3D mode if these features must be used.
-
-
- C) Hardware 3D, Compatibility
- Also on the settings window, you can enable hardware 3D acceleration. You must have a
- video card with at least 16MB of Video RAM to enable this, and it works better with 32MB
- video cards. Certain older, more obscure 3D cards may be unable in the hardware mode even
- with sufficient RAM. Number Nine Revolution cards and Voodoo Banshee cards will not run
- correctly in hardware 3D mode. Hardware 3D does not work at all in Windows NT 4.
-
- Cards and/or chipsets that have been successfully tested in hardware 3D mode in Tropico
- (with 16 MB of video RAM or more), include:
-
- Nvidia TNT 1/2 (See Troubleshooting tip G)
- NVidia GeForce 1/2
- 3DFX Voodoo 3 (See troubleshooting tip E)
- 3DFX Voodoo 4 and 5
- ATI Rage 128 (aka ATI Rage Fury)
- ATI Rage Fury Maxx
- ATI Radeon
- Matrox G400
- S3 Savage 4
- 3DLabs Permedia 3 (See troubleshooting tip E)
- NEC Power VR2 / Power VR3 (See troubleshooting tip F)
-
- If, in the process of switching to hardware mode, Tropico crashes, and then is unable to
- run thereafter, launch the game in 'Safe Mode', which will reset Tropico to use software
- 3D mode. In general, if you aren't sure if your system can run in hardware 3D mode, try
- it, and fall back to software 3D mode if the results are unsatisfactory. We have tested
- Tropico on a wide variety of video cards (including many not listed above), and Tropico
- works in software 3D mode on all of them.
-
-
- D) Hardware 3D, Performance
- Hardware 3D works well early in the game, with relatively few units and buildings, but
- in some cases can actually increase choppiness late in the game with more people and
- buildings in play, as all available RAM on the video card is used. The options in the
- memory tab may also be useful for you if you're using hardware 3D - using fewer and
- lower detail images can result in smoother 3D acceleration.
-
-
- E) Hardware 3D, Jittery/Shifting Graphics
- On some video cards, in Hardware 3D mode, the game's graphics can appear to shift around
- or jitter by a few pixels at times. This has been reported on Voodoo 3 cards and
- Permedia 3 - based cards. This problem can usually be eliminated by enabling the
- 'Reduced Graphics Shifting' option, in the settings window (press <F2> in the main game
- world to bring this up.) The downside to this is that it can reduce graphics performance
- (i.e. frame rate), by 5-25%.
-
-
- F) Hardware 3D, Corrupt graphics on Power VR2 or Power VR3 based card
- On NEC Power VR2 and Power VR3 based cards, switching to Hardware 3D will result in graphics
- that are highly splotchy, possibly with most of the screen blackened and only splotches
- of graphics visible. This can be resolved by enabling 'Reduced Graphics Shifting', in
- the settings window (press <F2> in the main game world to bring this up.)
-
-
- G) Hardware 3D, Cracks in buildings on TNT & GeForce cards
- If you're using hardware 3D with an NVidia video, particularly the TNT 1 or TNT 2,
- but conceivably also on GeForce cards, you may see jagged cracks or seams in buildings,
- where the terrain behind the building can be seen through the building itself. This
- is most noticeable if you're zoomed in close on a large building. This is because the
- buildings in Tropico are composed from a number of separate layers, and the NVidia cards
- sometimes introduce small errors when drawing these layers, causing gaps to show
- through the buildings. Here is a workaround found to usually work:
-
- 1) Make sure you have at least the Detonator 6.50 drivers or higher, previous versions
- do not have the necessary options enabled (go to www.nvidia.com for drivers)
- 2) Go into Display Properties (Right Click on an open area of the desktop, then
- select 'Properties')
- 3) Click the 'Settings' tab
- 4) Click the 'Advanced' button
- 5) Click on the tab that says TNT2, GeForce, or whatever the name of your card is
- 6) Click the 'Additional Properties' button
- 7) Click the 'Direct3D Settings' tab
- 8) Click the 'More Direct3D' button
- 9) Adjust the Texel Alignment slider. The default is 3, but the cracking problem is
- often resolved on the values of 7, 5, and 0
-
- Note: This is not the same issue as faint, straight horizontal and vertical lines sometimes
- seen in buildings and trees while using ATI Radeon cards. The ATI Radeon problem is rare,
- and there is no resolution for the issue (fortunately, the effect itself is slight and seldom
- seen).
-
-
- H) Hardware 3D, Flickering Mouse Cursor and/or Garbage Underneath Mouse Cursor During Movement
- If your mouse cursor flickers throughout the game, or if the mouse sometimes leaves
- patches of garbage underneath as you move it around, this is typically a problem with your
- mouse drivers, sometimes seen on older computers using the original Windows 95. Update your
- mouse drivers and the problem will often diminish or disappear completely. Also, consider
- using software 3D mode, which usually resolves the problem. Finally, if you're using a color
- or animated mouse cursor on your desktop, try switching to the Windows default black and white,
- unanimated cursors.
