By default, aPriori uses an Open GL graphics driver to render the cost component in the Viewer pane. Most users should have no need to change the graphics driver setting. If you are experiencing display issues (such as an image of the part that appears to be incomplete, with missing or extra triangles displayed on the window), then it may be resolved by specifying a different graphics driver.

To change the graphics driver used by aPriori, select Tools > User Preferences > Viewer and then select from among the supported drivers. Please contact aPriori Support if you continue to experience display issues or instability.
