Mobile game development with Unreal Engine 5 presents unique challenges. The powerful Nanite and Lumen systems that make UE5 spectacular on PC need careful consideration on mobile.
In this deep dive, we explore LOD management, texture streaming strategies, and shader optimization techniques that helped us achieve 60fps gameplay on mid-range devices. We also cover the importance of profiling early and often, using tools like Unreal Insights to identify bottlenecks before they become problems.
Key takeaways include: batch draw calls aggressively, use mobile-specific material nodes, and never underestimate the power of good occlusion culling.
