Try UET – Universal Ultimate Engine Tweaks, not the older Wukong-specific “Ultimate Engine Tweaks” listing: that page is marked obsolete and points users to UET, its universal successor. UET is a custom Unreal Engine Engine.ini configuration, not a hardware upgrade. Its author says it can reduce stutters and improve performance, but the listing provides no independent Black Myth: Wukong benchmarks, so it is not a guaranteed fix for lag spikes.
What the new mod is—and what it claims to do
P40L0’s UET changes Unreal Engine settings through an Engine.ini file. The author describes its goal as reducing stutters, improving performance and stability, lowering input latency, and improving image clarity without visual loss. Those are the creator’s claims, not independently verified results for Black Myth: Wukong.
The older Wukong-specific mod page was marked hidden and obsolete on September 21, 2026, and directs users to the universal listing. The current Nexus Mods listing identifies UET as version 137, last updated October 2, 2026. Its changelog says version 136 addressed occasional crashes in specific games, including Wukong; version 137’s listed fixes concern performance drops and visual regressions in other specific games, not Wukong.
P40L0 reports that the project followed more than two years of iterative testing, research, and feedback, and has over 1.7 million downloads across more than 60 Unreal Engine 5 and 4 games. These are figures reported by the author on the UET listing, not proof that it fixes Wukong stutters.

Choose the right UET variant
The listing offers VRR and No VRR variants. These are configuration choices, not performance tiers:
- VRR: choose this only if variable refresh rate is enabled both in your NVIDIA or AMD control panel and on your display.
- No VRR: choose this if VRR is not enabled in both places.
The author warns not to use UET alongside other optimization mods. The listing says other mods are compatible, but that does not override the warning about optimization mods.

Install UET
- Launch Black Myth: Wukong once so the game creates its configuration files.
- Download the preferred Engine.ini variant from the UET Nexus Mods page.
- Follow the page’s installation path for your setup: Windows, Microsoft Store/Xbox App, or Linux/Steam Deck. The correct configuration folder differs by platform and store.
- If an
Engine.inialready exists, the author instructs users to append the supplied settings beneath the stock lines. Save the file and set it to read-only, as directed by the listing.
To undo the configuration, delete the modded Engine.ini; the author says the game restores its defaults on the next launch. If you troubleshoot by removing it, keep a copy of your original file first if you want to preserve custom settings.
What to check if lag spikes continue
UET is one configuration to try, not a diagnosis of every spike. Steam lists 130 GB of available storage for the game and recommends an SSD at minimum specifications; SSD storage is required at recommended specifications. That is setup guidance, not evidence that moving the game to an SSD will cure stutters. See Steam’s Black Myth: Wukong technical issue and system requirements page for the official details.

If you test UET, change one thing at a time: use the variant matching your VRR setup, avoid stacking optimization mods, and compare play with and without the configuration. The current listing does not provide controlled Wukong-specific benchmark results, so whether it helps on a particular PC remains uncertain.
