Performance Optimization Settings

Performance in CADian can be optimized using various system variables. Some of the most important ones are listed below.

MULTICORE

Some CADian functions can use multiple CPU cores. This system variable controls how many CPU cores are used.

The default value is 0.

Values

-2 = Automatically selects one of the available CPUs.
If other CADian processes are already running, the CPU with the fewest CADian processes is selected. Otherwise, a random available CPU is chosen.

-1 = uses all available CPUs.

0 = uses the CPU(s) assigned when the program was started.

1 = If CADian processes are already running, CADian selects a single CPU with the fewest CADian processes from all available CPUs. If no other CADian processes are running, a random CPU from the originally assigned CPU list is used.

2 to 64 = uses the specified number of CPUs.
If the value is higher than the number of available CPUs, all CPUs are used automatically.

TEXTQLTY

Controls the display quality of TrueType text.

Values

0 = Draft Quality
Text is displayed faster but with lower visual quality.

100 = High Quality
Text is displayed smoother and cleaner but requires more processing power.

RTDISPLAY

Controls the real-time display of raster images during zoom and pan operations.

Values

0 = Images are displayed during real-time zoom/pan
→ smoother visual display, but higher graphics load

1 = Raster images are not displayed during real-time zoom/pan
→ better performance

The default value is 1.

LINESMOOTHING

Controls anti-aliasing for lines on the screen.

Values

0 = Disabled
No line smoothing. Display performance is faster, but lines appear more jagged.

1 = Enabled
Lines are displayed smoother. Visual quality improves, but more graphics performance is required.

GRAPHICSCONFIG

Opens the graphics performance and hardware acceleration settings.

This command allows adjustment of various graphics features that affect display quality and overall performance, including:

• Hardware acceleration
• Line smoothing
• High-quality geometry
• GPU usage
• Display effects
• Graphics performance options
