GRAPHICSCONFIG (Command)
This dialog box controls hardware acceleration, changes 2D and 3D display settings, and diagnoses common graphics card configuration issues.
Some advanced graphic performance settings are only accessible if you enter -GRAPHICSCONFIG on the command line.
Effects Settings Tab
Displays options for hardware acceleration, as well as 2D and 3D display settings.
- Hardware Acceleration
- Enables the use of hardware acceleration and provides control to all effects settings available for the current driver. When off, only the smooth line display option is enabled and the mode switches to the default Software Mode.
- 2D Display Settings
- Enables the use of hardware acceleration and provides control to all effects settings available for the current driver. When off, only the smooth line display option is enabled.
- Mode Dropdown List
- Select an appropriate configuration mode based on your graphic card. By default, the advanced mode is selected for DirectX 12 graphic cards.
- Advanced Mode - Recommended for high end graphics cards that include a significant amount of memory and processing capability.
- Intermediate Mode - Recommended for mid-level graphics cards that have some processing capability but a limited amount of memory.
- Basic Mode - Recommended for entry-level graphics cards that have minimal processing capability and limited or no memory.
- Details Button
- Controls the display of 2D options. By default, smooth line display and video caching memory level options are collapsed in the display. Click on the Details button to view these options.
- Smooth Line Display
- Controls the status of the full screen anti-aliasing effect. This option removes the jagged effect on the display of diagonal lines and curved edges.
- Accelerated Font Display
- Enhances the visual quality of TrueType fonts by using GPU acceleration.
Important: Disable this option if you encounter problems with the text display.
- Video Memory Caching Level
- With high end graphics cards, you can control the amount of video memory that will be used to cache graphics. A larger value will have better performance, unless other applications are also using video memory.
-
Note: It is recommended that you do not use remote access applications, such as NetMeeting, Remote Desktop, or any other Windows emulating software, with hardware acceleration. These can cause general display failure and instability.
- 3D Display Settings
- Enables the use of hardware acceleration and provides control to all effects settings available for the current driver. When off, only the smooth line display option is enabled.
- Fast Shaded Mode
- Controls whether the cross-platform 3D graphics system is turned on or off.
- Advanced Material Effects
- Controls the status of the advanced materials effect on-screen.
- Full Shadow Display
- Enables shadows to be displayed in the viewport.
- Per-Pixel Lighting (Phong)
- Enables the computation of colors for individual pixels. With this option turned on, the 3D objects and lighting effects appear smoother in the viewport.
- Restore Defaults
- Resets the values to the defaults based on the Graphics Performance’s evaluation of the graphics card.
- Tuner Log
- Displays the tuner log, which reads your system and decides whether to use software or hardware implementation for features that support both. Features that work with your system are turned on, and features that might not work with your system are turned off. A log file displays the results, including information about your graphics card.
Diagnosis Tab
Displays the status of the graphics card configuration, helping you troubleshoot performance or configuration issues.
Indicates no graphics performance problems.
Indicates issue and suggested actions to improve performance.
- Hardware Acceleration
- When hardware acceleration is off, this will result in lower performance.
- Graphics Card Driver
- This indicates whether the graphics card driver is up to date.
- Dual Graphics Cards
- In the case of two graphics cards, make sure the higher performance graphics card is active.
- DirectX 12
- Graphics cards must support Direct3D Feature Level 12_0 or above to fully support AutoCAD features.
- High Resolution Display
- When the graphics card cannot fully support the resolution, reduce the resolution or update the graphics card.
- Automatic Configuration
- Check that automatic configuration is enabled. Remove the GS_DEVICE or GFXDX12 override to optimize performance.
