View a comprehensive history of all the performance optimisations in Construct 3 since the first release.
Improve editor performance when changing mouse cursors with lots of content visible
Improved frame scheduling for smoothness & low latency, particularly in worker mode
Use lower-latency mouse/touch input where supported in worker mode
Enable WebGL parallel shader compilation where supported, for faster editor & runtime startup
Optimise handling disabled Solid behaviors
Optimise general collision engine performance when dealing with large numbers of instances
Optimise handling lots of Bullet behaviors with both the Solid behavior and 'Bounce off solids' enabled
Further reduce memory usage of instances
Reduce memory use of instances (improves quadissueperf benchmark)
Improve quadissueperf & bboxperf benchmarks performance (should resolve performance regression since r150)
Cloud save: reduced network requests per Dropbox action
Optimise editor loading time by loading more resources after Start Page appears
Optimise editor loading time by reducing number of network requests and loading more resources in parallel
Optimise editor loading time by deferring more loading work until after the Start Page appears
Optimised general event performance (in C3 runtime)
