Issue:
How to turn video hardware acceleration on or off in AutoCAD to improve graphics performance.Causes:
Turning on hardware acceleration improves graphics performance and productivity. This helps overall performance, not just with 3D work.If unexpected problems are appearing with specific video cards and drivers, toggle hardware acceleration on and off.
Solution:
There are several ways to toggle hardware acceleration in AutoCAD-based products. Try one of the following methods:
- Enter the GRAPHICSCONFIG command and click Hardware Configuration.
- Enter the 3DCONFIG command and click Hardware Configuration.
- Enter the OPTIONS command or choose it from the Application menu to open the Options dialog box. On the System tab, click Graphics Performance. Then click Hardware Acceleration to turn it off or on.
- Click GRAPHICSCONFIG performance in the lower-right corner of the AutoCAD/Civil 3D application window. Snip for reference:
There may be a delay the first time using GRAPHICSCONFIG or 3DCONFIG or when clicking the performance button.
Note: The interface options may differ, depending on product and product version. AutoCAD LT 2011 and earlier do not support hardware acceleration and do not have 3DCONFIG.
