Which graphics card has the best performance with VISSIM 3D?
Best results are achieved with graphics cards using nVidia® Geforce® chipsets. In history we’ve experienced some problems with ATI® chipsets as some graphics funtionality was done through software rather than hardware. In general the most important thing is full compatibility with OpenGL®. In order to find out if a graphics card has this feature you could check graphics cards test reports which show the behavior and speed when running OpenGL® applications. A lot of graphics RAM is important if you have a 3D scene highly loaded with textures. For standard 3D applications 64 MB of graphics RAM are sufficient. It is also important to use the latest graphics driver. If in doubt, try it out (e.g. with a VISSIM demo version).

Best results are achieved with graphics cards using nVidia® Geforce® chipsets. nVidia® Quadro® chipsets do not offer any better performance for VISSIM applications so you’re better off to spend the money to get a high-performance Geforce® card. With ATI® chipsets we’ve experienced problems as some graphics functionality was done through software rather than hardware and hence full compatibility is not ensured. The most important feature for use with VISSIM is full compatibility with OpenGL®. In order to find out if a graphics card has this feature you could check graphics cards test reports which show the behavior and speed when running OpenGL® applications. If in doubt, try it out (e.g. with a VISSIM demo version). A lot of graphics RAM is important if you have a 3D scene highly loaded with textures. For standard 3D applications 128 MB of graphics RAM are sufficient. It is also important to use the latest graphics driver that is available from the manufacturer’s website. For customers
