Altium Designer 14.3 delivers a number of system and performance-related enhancements, including:

• The project compiler has been updated such that it can persist information from previous compiles. This results in greatly reduced memory requirements and improved speed.
• DirectX memory limits have been increased, improving stability for larger designs.
• 3D model meshing has been improved. 3D model information is cached between sessions, providing faster load and switching times during sessions.
• 3D PCB Flex rendering has been improved.
• Room movement has been improved, including reduced delay before the start of the move, and smoother movement for all primitives associated to the room being moved. All mechanical layers are hidden during the move, as well as all strings.
• Schematic connectivity analysis has been optimized to remove delay during dragging.
• To increase performance within the PCB Editor, the following design rule types have been disabled by default, with respect to online rule checking:
  • Unpoured Polygon
  • Assembly Testpoint Usage
  • Assembly Testpoint Style
  • Fabrication Testpoint Style
  • Fabrication Testpoint Usage
  • Acute Angle
  • Hole Size
  • Hole To Hole Clearance
  • Layer Pairs
  • Minimum Annular Ring
  • Minimum Solder Mask Sliver
  • Net Antennae
  • Silk To BoardRegion Clearance
  • Silk To Solder Mask Clearance
• Optimized loading speed for large libraries, when loaded into the Libraries panel.
• Integrated Library compiling (memory usage and speed) has been improved.
• Application startup speed has been improved.
• A Windows system resource monitor has been implemented within Altium Designer. When resource consumption gets a level considered to be high, a resource warning flag appears down the bottom right of Altium Designer. Hover the cursor over the flag for information about the current resource consumption, as shown in the images below. Note that the color of the warning flag changes to highlight the level of resource consumption, and the message indicates when a restart is advisable.

A warning flag appears when Altium Designer's resource consumption becomes high, and changes color to indicate when action is required.

• The following resources are monitored:
  • Memory used by Altium Designer
  • Count of allocated GDI handles
  • Percentage of allocated global and session atoms

• The resource monitor triggers and displays a warning flag when any of the above resources reach the following levels:
  • < 60% normal level (no resource flag is displayed)
  • 61% to 75% is considered a high level, indicated by a yellow flag
  • 76% to 90% is considered a very high level, indicated by an orange flag
  • > 90% is considered a critical level, indicated by a red flag
