HOW TO USE GPU
Autodesk AutoCAD (v.2022 and newer)
AutoCAD is a powerful software for 2D drafting and 3D modeling. Enabling GPU acceleration improves performance by utilizing the system's GPU, significantly speeding up graphics rendering and operations like zooming, panning, and rotating complex models. Here’s how to activate GPU acceleration and optimize performance.
How to Enable GPU Acceleration in AutoCAD
Launch AutoCAD
Open AutoCAD from the default location:C:\Program Files\Autodesk\AutoCAD 20##\acad.exe
Enable Hardware Acceleration
Open a blank document.
Click the Autodesk icon at the top left, then go to Options.
In the System tab, under Graphics Performance, ensure Hardware Acceleration is On.
Set 2D Display Settings to Advanced Mode for smoother navigation.
In 3D Display Settings, enable all available options (such as Shadows and Smooth Line Display) to improve rendering quality and performance.
These settings allow AutoCAD to offload many tasks from the CPU to the GPU, making it faster when working on complex designs.
Top Tips to Speed Up AutoCAD
Update GPU Drivers
Always keep your NVIDIA or AMD drivers updated. Certified drivers ensure compatibility and performance, especially for AutoCAD's hardware-accelerated features.Optimize Drawings
Use the PURGE command to clean up unused layers and blocks and the AUDIT command to fix drawing errors. Additionally, reduce drawing complexity by simplifying layers and using External References (Xrefs), which allow AutoCAD to load referenced files only when needed, improving speed during editing.Fine-Tune Graphics Settings
Use the GRAPHICSCONFIG command to access advanced performance settings. If you’re running on a lower-end system, switching to Intermediate Mode instead of Advanced Mode may help balance quality and speed, especially when handling large projects.Use SSD Storage
Storing your project files on an SSD ensures faster load times and improves performance when working with large files.
Top Recommended GPUs for AutoCAD
