NVIDIA Releases Hotfix Driver Fixing Windows Slowdown
8.0
NVIDIA released GeForce Hotfix Display Driver version 581.94 on November 19, 2025 to address reports that Windows 11 update KB5066835 (and possibly optional KB5065789) reduced game framerates on systems with NVIDIA GPUs. Affected users reported framerates cut as much as half across Windows 11 24H2 and 25H2; NVIDIA notes the hotfix is beta and recommends waiting for the next WHQL-certified driver for full stability.
