Performance Monitoring Flashcards

Circles and arcs appear as polygons when zoomed in. Which system variable controls the resolution of curved objects in the current viewport?

Answer: VIEWRES

VIEWRES sets the circle zoom percent, controlling how smoothly circles and arcs display, up to a maximum of 20000.

Which system variable controls the smoothness of shaded and rendered 3D solids with curved surfaces?

Answer: FACETRES

FACETRES adjusts tessellation of shaded and rendered curved solids, with higher values increasing display time.

Animated zoom and pan transitions are slowing down navigation on a low-end workstation. Which setting turns them off?

Answer: VTENABLE = 0

VTENABLE controls smooth view transitions, and setting it to 0 disables them.

Which system variable controls multithreaded processing for regenerations and redraws?

Answer: WHIPTHREAD

WHIPTHREAD enables multiple processors or cores for regen and redraw operations, with 3 enabling both by default.

Selecting a large set of objects causes a delay while grips are calculated. Which variable suppresses grips when the selection exceeds a specified number of objects?

Answer: GRIPOBJLIMIT

GRIPOBJLIMIT stops grips from displaying when more objects than its value are selected, with a default of 100.

Which variable limits the number of objects that show selection preview highlighting during window or crossing selection?

Answer: SELECTIONPREVIEWLIMIT

SELECTIONPREVIEWLIMIT caps how many objects receive preview highlighting, preventing slowdowns in dense areas.

Showing object transparency is causing slow display in a complex drawing. Which variable turns off transparency display?

Answer: TRANSPARENCYDISPLAY = 0

TRANSPARENCYDISPLAY controls whether object transparency is shown, and disabling it can improve display performance.
