The Elder Scrolls 4: Oblivion Remastered utilizes an Unreal Engine 5 wrapper to enhance the original game, but it carries over some of the original's issues and suffers from significant performance challenges, including frequent stuttering. Digital Foundry analyzed the remaster against the original 2006 version, highlighting advancements in graphics but also noting that the remaster struggles with limited polygon budgets and basic effects. The remaster's performance is inconsistent, especially on mid-range CPUs, leading to poor experiences even on high-end hardware. Disabling hardware RT-based Lumen global illumination can improve performance by about 35%, but at the cost of visual quality. Lowering settings yields only marginal performance improvements, and the game fails to deliver an attractive experience compared to the original. A recent patch did not resolve the stuttering issues, indicating that fundamental CPU-related problems remain unaddressed.
