Model Display Performance Improvements

SOLIDWORKS 2021 offers improved performance for occlusion culling, silhouette edges, and drawings. You can switch configurations quickly.

Feature Areas of Improvement
GPU-based Occlusion Culling
  • Boosts dynamics performance for large assemblies and parts in resolved, LAM, and LDR (Large Design Review) modes.
  • Legacy or nonrender pipelines

Hidden geometry based on view direction and view frustum is not rendered.

Performance scales with low-end to high-end GPUs.
GPU-based Silhouette Edges
  • Large assemblies and parts while in HLR (Hidden Lines Removed), HLG (Hidden Lines Grayed), and Wireframe modes
  • Shaded with edges and edge modes
Drawing The performance is improved for drawings when panning and zooming.
Switching Configuration of Large Assemblies
  • Large assemblies
  • Multilevel assemblies with components that have overridden properties (appearance, display mode, visibility, and referred display state)
