Micro-stuttering in Unreal Engine 5 titles is a prevalent issue. Epic is now offering developers various remedies.
Few game engines epitomize visual excellence like Unreal Engine 5. Nevertheless, numerous games now encounter stuttering and performance issues tied to Epic’s engine. The company has begun providing a suite of resolutions for developers.
## Epic takes aim at micro stuttering
An entertaining yet genuinely thrilling session from Unreal Fest 2025, held in Orlando at the start of June, has recently been shared on the Unreal Engine YouTube channel. It features Epic software engineer Ari Arnbjörnsson, outfitted in a witch hunter costume, calling for a “Hitch Hunt,” or a mission to eradicate micro stutters.
These issues affect many games built on Unreal Engine 5. During the presentation, Epic outlined several causes of these micro-stutters, identified through discussions with various studios. Several potential solutions were also presented.
Seven reasons for micro stuttering are addressed:
– **Level streaming problems:** Frequently resulting from improper handling of static objects, causing memory overload and repeated garbage collection.
– **Physics optimization:** Numerous developers neglect to optimize physics, depending on Nanite, but intricate geometry without collision simplification adds extra load.
– **Spawn actors:** Particularly with complex NPCs, which may induce stuttering upon spawning.
– **Compiling PSO shaders during gameplay:** Even with the PSO cache introduced in UE 5.3, this remains a prevalent source of PC freezes.
– **Garbage Collector:** Can lead to stuttering if it fails to operate incrementally.
– **Synchronous asset loading:** When assets are loaded synchronously, it blocks the render thread, resulting in stuttering.
– **Blueprint overload:** Overuse or inefficient implementation of blueprints can also impact performance.
Epic emphasizes that improved optimization and better resource utilization are critical to avoid these problems. Developers should incorporate established optimization techniques into the development process at the earliest stages to prevent issues from emerging.
