What Altium needs is a performance mode, something kinda like Telsa's ludicrous button.
Here are some tweaks to increase performance for larger designs.
Start and Save Projects:
Supplier Links - Disable all live supplier links and supplier data for faster startup, fast BOMs and a more responsive Library Panel.
Live Supplier data causes lags when scrolling the Library Panel, this is due to real time supplier website searches.
The engineers I'm working with prefer to go to directly Digi-Key, Mouser or Octopart and search for parts, they do not use Altium's built-in Supplier Search feature.
During Layout:
Uncheck Cross Select Mode. Large projects with many schematic sheets will cause the tool to craw.
Online DRCs - Turn off online DRC Checks in DXP Preferences. Or minimize Online DRCs.
Live Drill Table - Delete and do not display the live drill table until you are ready to generate the fabrication data. The live drill table causes sluggish routing and via placement lags in large projects. This was fixed in later versions of Altium Designer by disabling live Drill tables.
PCB Panel - Keep the PCB panel keep it closed unless it is needed, live updates occur while routing when the PCB Panel is open causing sluggish routing.
Delete Rules - Delete unused rules, disabling rules may not help.
Minimalize Rules - Try disabling rules. Or Export rule and Import after routing.
Polygon Repours - Turn off "Repour Polygons After Modification" option in DXP Preferences/PCB Editor/ General
Polygon pours - Use coarse Arc Approximations, fine arcs take longer to process. Note coarse Arc Approximations will effect copper clearances. For co-planar (CPW) RF traces you may want to use finer settings for Arc Approximation. Use finer settings after the routing is done.
PCB Rules and Violations Panel - Keep the Panel closed to eliminate sluggish lags while moving tracks to fix DRCs.
Via Stitching - Do NOT Use Via Stitching !
Disable the Cross Select Mode
