• Adjust the graphical settings of your viewports to reduce the amount of processing required when dynamically manipulating models, or redrawing viewports. By using edged mode, you can double the speed of dynamic viewing.

• Blending creates complex surfaces, so the processing time for the display and modification of blended edges is longer than the time needed for less complex surfaces. Leave blending operations until your part is nearly finished if Creo Elements/Direct Modeling is experiencing performance problems.

• The use of lights within Creo Elements/Direct Modeling may occasionally affect performance. Depending on your hardware configuration, any active positional light may negatively influence the performance.

◦ Creo Elements/Direct Modeling is optimized for up to 15 directional lights. By default, lights 0 to 7 are active while the other seven are inactive. The less lights that are active, the better the performance of Creo Elements/Direct Modeling.

• The fewer features that you activate in the Show menu, the less Creo Elements/Direct Modeling needs to calculate.

• Low performance can be related to your graphics card. Even with a top-quality graphics card you may notice a performance reduction ifone viewport obscures another. Try to avoid overlapping viewports to maintain performance.

• In several part modification functions, you can switch off the body checking function. This can increase the performance when modifying a part in several steps. Switch body checking back on before accepting the final modification.
