GenesisIV Tutorial: Startup issues |
GenesisIV makes use of advanced OpenGL graphics functions which can cause problems with older cards, unusual graphics configurations, or buggy drivers. GenesisIV should automatically configure itself for many of these issues on first running, but if problems do arise the following should be helpful. You may also like to ask any questions on our support forum. GenesisIV stores all landscape information in a relational database, which means that the database must be available when GenesisIV is running. In previous versions of the program this ran as a separate server, but from version 6.0.5 onwards this is integrated into GenesisIV. The instructions to check the database server are retained below, but should be ignored for all current downloads. |

| Graphics Card Issues | GenesisIV uses OpenGL to produce all it's 3D images, and depends upon shaders, a recent addition to the OpenGL specification to process much of the lighting effects. Shaders are new to OpenGL, being added in version 1.4 and later. We keep a list of card which GenesisIV can work with, but effectively any reasonably recent card by nVidia, or 3DLabs should be ok. ATi support for OpenGL has tended to be less reliable and for these it is often essential that the latest drivers are loaded. Lower range ATi cards may also produce rendering artifacts. Occassionally on some systems, nearly always with ATi cards, even with a the latest drivers and a correct database installation the program crashes on startup - usually silently after displaying the splash screen but sometimes displaying error 216 or similar. In these cases running GenesisIV without shader support should solve the problem. To run without shaders click on the Genesis IV (no shaders) icon. When running in this mode all functions other than the photorealistic renderer will work as normal. The photorealistic renderer itself will be somewhat slower, will not render vegetation or 3D models correctly shaded, and there may be some minor differences in atmospheric effects. We are working on a set of reduced shaders that will reliably work with ATi cards. A useful check in these cases to confirm the problem is graphics hardware/drivers
related is to run GenesisIV as normal (with shaders) but reducing the
DirectX hardware acceleration level. Right click on your desktop, choose
properties, then the settings tab, followed by the advanced button and
finally the troubleshoot tab to display a dialog similar to the below.
Moving the hardware acceleration slider down from full to the position shown stops DirectX crashing the OpenGL rendering system. If the program now runs without a crash on startup, this confirms that the problem lies with the graphics card and/or drivers. Further information may be available on our support forums. |

| Database Issues | These usually manifest themselves as GenesisIV either failing to start or crashing after startup. The following steps usually correct any problem.
