Dear Epic Games Engine Team,
I am reaching out as a PC enthusiast and player to provide critical feedback regarding the current state of Unreal Engine 5’s performance, specifically concerning its asset-streaming and memory-management systems in modern titles (such as S.T.A.L.K.E.R. 2).
My system is equipped with the highest-end hardware available on the market today: an AMD Ryzen 7 9800X3D and an NVIDIA GeForce RTX 5090, running on a fully stable, stock configuration with optimized high-speed RAM.
Despite this raw computing power, UE5 titles suffer from severe, persistent, and unpredictable micro-stutters. Through rigorous testing, I have identified that these issues are completely independent of graphical settings, DLSS profiles, or framerate caps.
The two most prominent issues are:
1. Aggressive and Unoptimized Garbage Collection: The engine seems to completely flush previously visited zones from its short-term memory too quickly. Returning to a major hub or safe zone just 15 to 20 minutes later causes immediate, consecutive traversal and script-loading stutters, as the engine forcedly re-allocates assets that should have remained cached.
2. Dynamic / Ambient Stuttering: Beyond predictable traversal boundaries, the engine frequently hitches when handling dynamic background scripts and asset injection (such as ambient AI systems), leading to a highly erratic frame pacing that ruins the gameplay experience.
As PC players, we are seeing a massive technical regression. Hardware brute-force cannot fix core engine architectural bottlenecks. I strongly urge the UE5 engineering team to prioritize fundamental rewrites of the data-streaming pipeline and garbage collection cycles over purely visual features in upcoming engine updates.
Thank you for your time and for addressing these critical optimization flaws.
Best regards,
Niel
