It’s finally here! My Performance Optimization Course for Unreal Engine is launching today!. With 65+ lessons completed and more on the way! I’m so excited to have people dig in! Get $50,- off for a limited time.

Got my ticket for Unreal Fest Stockholm! Looking forward to meeting everyone this year! My talk wasn't approved though, so just attending. .

RT @phyronnaz: Property History is out!. Quickly see the history of any property in Unreal Engine

RT @WWeynants: 1/5 🧵. Just launched PCG Geometry Decals for UE 5.5+ #UnrealEngine 🚀. Drop ➜ Snap ➜ Displace ➜ Bake ➜ Nanite. Instant, terra….

RT @toreler: My plugin for @UnrealEngine is almost done! It lets you blend any mesh. Not just landscape, not PDO. This magic lets you ble….

RT @94Kiraly: We've got our first Community Learning post up! If you're interested in Untracked Memory in #UnrealEngine5 give this one a re….

Character & Projectile Movement Components do not use this grouped update behavior at this time as it requires specifying the scoped movement with EScopedUpdate::DeferredGroupUpdates instead of the current EScopedUpdate::DeferredUpdates.

UE 5.6 supports Grouped Component Movement to defer scene component moves for batching later in the frame!. This feature is part of FScopedMovementUpdate, toggle with s.GroupedComponentMovement.Enable and specify EScopedUpdate::DeferredGroupUpdates during the scoped movement.

UnrealFest Stream 3, Day 1 is blocked.

Time to dig into the UE 5.6 Release Notes!. Excited for the incredible performance improvements this release, I'll be working on another "Performance Highlights" blog asap!.

Join me as we deep dive into the variety of Variable Rate Shading Techniques on offer in Unreal Engine 5! . VRS reduces your pixel shader workloads, potentially taking multiple milliseconds off your GPU timings. Start here:

other limitations: masked materials, custom primitive data on the material, or using Substrate all prevent VRS from running on those pixels. The custom primitive data one is most surprising.

The Code & Reason

TIL the new software VRS does not work while any Lumen feature (diffuseindirect / reflection) is enabled. It will fallback to the hardware implementation instead (shown). quite the (unspecified) limitation!

Animation Budget Allocator:

Significance Manager:

Added two new lessons to the Optimization Course! A deep dive into Significance Manager with implementation example for a Bucket System & Animation Budget Allocator plugin to manage gamethread budgets for animation!.

Watch me optimize Dark Ruins Sample project for an hour:. This was mostly unscripted, so hope it's useful! We need many more hours to run this on a steam deck though lol.
