    "prose": "On 2026-08-28, mVolt+ creator b00nz stated via X post that Nvidia's latest driver 615.56 blocks the app's core power limit settings on RTX 50-series GPUs, causing it to blackout as if the tool had crashed. [^1]\n\nmVolt+ is an open-source software that circumvented standard driver restrictions to allow power and voltage overrides for RTX 50-series GPUs, enabling separate power limits for core and memory, and offsets for core, XBAR, SYS, and VRAM. [^2]\n\nSome users on the Overclock.net RTX 5090 thread reported that their GPUs still accept power limit modifications via the Hydra 2.3B Pro overclocking utility, suggesting mVolt+ wasn't explicitly blocked and its creator b00nz could push a fix. [^3]\n\nThe Blood of Dawnwalker runs stably on a high-end PC equipped with an AMD Ryzen 7 9850X3D, 32GB of RAM, and an Nvidia GeForce RTX 5090, delivering 70-80 fps at 4K resolution with Ultra preset and DLSS set to Quality. [^4]\n\nUnlike other Unreal Engine 5 titles such as Star Wars Zero Company and Halo: Campaign Evolved, The Blood of Dawnwalker does not suffer from constant stuttering or crashing issues. [^5]\n\nTom's Hardware reports that mVolt+ allowed enthusiasts to chart on 3DMark's worldwide rankings purely through software, but real-world performance gains were marginal, and whether Nvidia intentionally blocked it remains unverified. [^6]\n\nOn the Steam Machine, The Blood of Dawnwalker runs at 55-60 fps at 1440p with mostly medium settings, avoiding the stuttering and crashes common on weaker hardware for Unreal Engine 5 games. [^7]\n\nThe Blood of Dawnwalker runs smoothly on the PS5 Pro at approximately 60 fps and on the Xbox Series X at 40-50 fps using the Performance and Balanced profiles respectively. [^8]",
