Nvidia's driver version 595.71 has introduced performance issues, limiting core clock speeds, voltage levels, and power outputs, resulting in performance drops of up to 16%. The update, released on March 2, aimed to fix problems from the previous version 595.59 but has negatively impacted overclocked graphics cards. For example, an RTX 5090 that previously achieved clock speeds over 3,100MHz now struggles to maintain speeds above 3,000MHz. Benchmark tests showed the older driver (591.74) achieving 171fps compared to 144fps with the new driver. Users are advised to revert to an earlier driver version from the 591 series to restore performance.
