Recent updates to Windows 11, specifically the October security and feature patch (KB5066835), have caused frame rate drops in games, with Digital Foundry reporting significant performance issues in Assassin's Creed Shadows. Testing with an AMD Ryzen 9800X3D and Nvidia RTX 5090 showed low frame rates until a hotfix from Nvidia was applied, which improved performance from 34fps to 72fps. Without the hotfix, gamers could see a performance decline of 33% to 50%. Anecdotal evidence suggests the hotfix may also improve performance in Counter-Strike 2, with an 11% increase in 1% lows reported. Nvidia's documentation indicates the hotfix addresses issues in "some games," but further testing is needed to determine if the performance issues affect only Nvidia GPUs or also AMD graphics cards. Gamers with recent Nvidia graphics cards experiencing performance dips are advised to download the hotfix.
