'Wizardry!' The Elder Scrolls IV: Oblivion Remastered's Most Popular Mod Is an 'Ultimate Engine Tweaks' PC Performance Fix — and There's a Very Good Reason Why

Author: Aurora May 03,2025

If you’re a fan of The Elder Scrolls IV: Oblivion Remastered on PC, you may have encountered several performance issues that have been widely discussed by the gaming community. According to the tech experts at Digital Foundry, the remastered version of Oblivion is plagued by "dire" performance problems. Video producer Alex Battaglia described it as "perhaps one of the worst-running games I've ever tested for Digital Foundry."

Battaglia elaborated, stating, "Even if you're running the most powerful hardware around, the stuttering is egregious, dragging down the experience to the point where I really don't understand how this was considered good enough for release." He also highlighted that the game is unusually resource-intensive, suggesting that players might need to lower their settings just to maintain an acceptable frame rate, despite tolerating the stuttering.

PlayGiven these performance issues, it's no surprise that the most-downloaded mod for Oblivion Remastered on Nexus Mods is P40L0’s ‘Ultimate Engine Tweaks (Anti-Stutters - Lower Latency - No Film Grain - No Chromatic Aberration - Lossless),’ which has seen an impressive 386,604 downloads in less than a week.

The mod description reads: "Definitive Unreal ‘Engine.ini’ changes with the goal to remove most stutters, improve performance and stability, decrease input latency, improve picture clarity. All with no visual loss."

P40L0 explained, "After months of UE5 testing, I would like to share my definitive custom ‘Engine.ini’ changes for the game. My goal was to include as many optimizations as possible (both for CPU/GPU/RAM/SSD) in order to remove most stuttering, improve performance, reduce input latency, and improve picture clarity (e.g., by removing Film Grain & Chromatic Aberration, optimizing DLSS/FSR upscaling, and more) all without any visual loss or introducing glitches or crashes."

Feedback from users who have downloaded the mod has been overwhelmingly positive. Chubbyd07 exclaimed, "Stutter be gone! Simply amazing, thanks!" Yeeto51 added, "This .ini is a miracle. From 15-20 fps outside the prison to 65-70 stable. Running on 3600XT and a 2060 with 20GB of RAM (yes)." BabaSmith was equally impressed, saying, "Uhm, what the hell! I went from 60fps on High Preset around Waynon Priory to 90-110fps on the same location. Wizardry!!"

Despite the PC version's issues, Oblivion Remastered continues to attract a large audience, boasting an impressive peak concurrent player count on Steam and over 4 million players across all platforms. On Steam, the game enjoys a 'very positive' user review rating.

However, a recent hotfix deployed on April 25 has disrupted Microsoft Store players' ability to adjust UI settings for graphics, particularly upscaling and anti-aliasing. As of this article's publication, those playing via Game Pass for PC cannot modify these settings due to a glitch in the settings UI. Bethesda has acknowledged the problem and is working on a solution.
