System requirements and recommendations for running Topos R2:
Operating System: Microsoft® Windows® Vista and Microsoft® Windows® 7. Topos should also still
run on Windows® XP Professional SP2 and Windows® XP Home SP2, but this has not been verified
recently. Topos has not been systematically testet on Windows® 8.1, but we have not seen any issues so
Processor: 32 or 64-bit Intel® or AMD® multi-core processor.
Memory: At least 4 GB RAM, but 8GB or more is recommended.
Graphics card: For best performance please use a recent dedicated graphics card with up to date drivers. Minimum requirement is a 3D graphics card supporting accelerated OpenGL 1.2 or higher, with 32 MB RAM. The graphics card must support vertex- and (for some features) fragment programs, that is, be a true DirectX 9 class graphics card. We currently recommend NVidia based cards rather than ATI based cards due to problems that we and others have seen in ATI's drivers. Furthermore, for better performance we recommend a graphics card with at least 512MB dedicated graphics memory. Topos may work on built-in graphics cards, like the ones from Intel®, but we due to performance issues we discurage it.
Hard disk space: If you install the documentation along with the program itself about 500 MB is required for installation. Note that DTM and drape data for
your projects will take up considerable amounts of hard disk space.
