NVIDIA has released the GeForce/RTX Spark Hotfix Driver 621.12 on October 27, 2026, to address a video freeze and black screen issue caused by the previous driver 621.01. This hotfix includes four fixes, primarily targeting the video playback problem on RTX 50-series GPUs, as well as issues related to Unreal Engine 5.8 crashes and display corruption with specific adapters. While the hotfix is optional and not WHQL-certified, it offers a solution for users experiencing the video freeze without losing Advanced Shader Delivery support, unlike rolling back to a previous driver. Users are advised to evaluate whether they are affected by the issues before deciding to install the hotfix, as it is considered beta software

NVIDIA released the GeForce/RTX Spark Hotfix Driver 621.12 on October 27, 2026, a rapid-response patch aimed squarely at a video-freeze and black-screen regression introduced by driver 621.01 three days earlier. The hotfix addresses four issues total: the headline video bug affecting RTX 50-series GPUs, an Unreal Engine 5.8 crash, RTX Spark display corruption through a StarTech Thunderbolt adapter, and flickering on the MSI Prestige N16 Flip. It ships as optional beta software that is not WHQL-certified and is available only through NVIDIA's Customer Care site. Users who aren't affected by any of the four issues can safely skip it, though those hit by the freeze may prefer the hotfix over rolling back to 617.42 since it keeps Advanced Shader Delivery support intact.
