Adjusts the adaptive viewport redraw methods.
The dialog contains the following options:
Select the boxes in each column to indicate the rendering modes the system will step through during necessary degradation. Those selected in the General Degradation column affect all inactive viewports, while those selected in the Active Degradation column affect only the active viewport.
Maintain FPS: Lets you set the frame rate in frames per second that the adaptive display system will attempt to maintain.
Reset on Mouse Up: Resets the rendering level as the mouse is released. If selected, the program tries various rendering levels to achieve optimal quality while still maintaining FPS. If clear, the program immediately drops the rendering level to the previous minimum.
Show rebuild cursor: Displays a cursor to show when the program is busy recalculating the viewport rendering.
Update Time: Sets the interval between updates during viewport rendering. At each interval, a new section of the rendering is drawn on screen. If set to 0, nothing is drawn until the rendering is complete.
Interrupt Time: Sets the interval between times when the program checks for a mouse-down event during viewport rendering. Small values free the mouse more quickly, so you can use the mouse elsewhere without waiting for it to “wake up.”
To override the adaptive degradation system, turn off the Degradation Override button in the Prompt line. Press o (lower-case O, for override) to turn off adaptive degradation, and press o again to turn it back on.
This is handy when you’re adjusting lights and want to see their effect, real time, in a shaded mode. Or you might be adjusting the camera and need to see complex geometry exactly as it is.
