Description

Optimizing UE5: Advanced Rendering, Graphics Performance, and Memory Management is Matt Oztalay's Unreal Fest 2024 talk on efficient Unreal Engine 5 next-gen rendering. Oztalay is a senior technical artist at Epic Games and focuses on GPU time and memory rather than introductory quality toggles.

He covers virtual textures, Nanite overdraw and cluster behavior, Lumen reflection costs, and virtual shadow map caching changes in UE 5.4, using complex Nanite foliage scenes to show misconfigured pools, trace limits, and World Position Offset pitfalls in debug views.

Advanced rendering programmers and technical artists benefit when Nanite, Lumen, and virtual shadow maps are already enabled but traces show silent memory growth. Epic published the recording free on YouTube as part of the Prague Fest livestream.

Widely cited in post-Fest technical-art notes as authoritative Epic guidance on UE5 rendering performance alongside Oztalay's other Nanite and Lumen sessions.
