Looking forward to upgrade…

Editor Performance Improvements

Efficiency of shader compilation through Incredibuild has been improved by 90% in some cases, leading to a 5x decrease in distributed shader compilation time with our internal setup.

Proxy mesh creation process is now better at scaling with the number of CPUs and can easily result in processing time reduction of more than 3x for complex setup.

Bulk convex hull computation on big scenes can be more than 100x faster than before and takes 4x less memory in some scenarios, taking a multi-hour long process to a couple minutes.

Material baking improvements have made it up to 14x faster and 3x less memory hungry than before, performance improvements may vary depending on which GPU backend is used.

Improvements in how Datasmith handle data reimports will result in a healthy decrease of both reimport times and memory usage.

A rework of how Datasmith CAD scenes are saved will make new CAD scenes save and load take seconds instead of minutes.

Datasmith VRED and DeltaGen FBX import workflow will now feel a lot snappier on huge FBX files.

Distance fields are now computed a lot more efficiently on many core CPUs leading to 5x reduction in processing time and better core utilization.

Exporting video production to PNG files is faster than ever and will make use of new instruction sets capabilities like AVX-2 when detected on your computer. It’s now possible to export a 4K video to loose PNG files in real-time on 16 Core CPUs.
