Psychtoolbox-3 - System Requirements


Operating system:
Runtime environment:
Additional software:
Basic hardware requirements:
Graphics hardware requirements:
Basic Psychtoolbox functions should work on any OpenGL 1.2 capable graphics card with at least 16 MB of video ram (VRAM). Fast stimulus drawing and use of the more advanced features requires recent graphics hardware. In general you should not try to save money on the gfx-adapter, as performance of your stimulus script may depend much more on the horsepower of your gfx-adapter than on the horsepower of your cpu.

Follow this link to our graphics hardware requirements page for detailed information about requirements for graphics hardware.

Users of the new Intel-based Macs should be aware that some iMacs (e.g., Intel MacBook) use a built-in Intel GMA graphics adaptor. These gfx-cards are known to have very low graphics performance and a very restricted feature set. They are cheap and sub-standard by any definition. The PTB evolves to use new OpenGL features as they appear in graphics cards. If you want to use these features or just want high performance graphics we recommend buying computers and cards that contain recent gfx-hardware from ATI or NVidia. See e.g., this Wikipedia article for further information.

The same holds true for most products of Matrox ans S3. As Matrox and S3 seem to have mostly retreated from the 3D graphics market, most of their products are not a good choice for OpenGL based applications like Psychtoolbox. Even the products that nominally claim to support hardware accelerated OpenGL, have a pretty limited feature set and performance, and the quality of their 3D drivers leaves something to be desired. If you're searching for a good graphics card for pure 2D imaging (non OpenGL , non PTB etc.), multi-display office work or medical imaging, they are a good choice though.

For the impatient, the following is a rough classification of gfx hardware by its suitability for PTB-3.
