Nvidia Issues Driver Reducing GPU Performance
7.1
Nvidia released driver 595.71 on March 2, which fixes fan-stopping bugs from 595.59 but now limits core clock, voltage and power on some GPUs, producing up to 16% lower performance in tests of RTX 5090 and other cards. Independent tests by Bang4BuckPC Gamer and WCCFTech show manual overclocks no longer reach prior peaks; affected users are advised to roll back to 591.74 or 591.86.
Key Points
- 1Limits core clocks and voltages on driver 595.71, causing up to 16% lower benchmark performance
- 2Erodes trust after consecutive buggy releases (595.59 fan fault, then 595.71 performance cap)
- 3Advise rolling back to 591.74/591.86 and avoid manual overclocking until Nvidia issues a fix
Scoring Rationale
Actionable hardware impact with clear rollback workaround; limited official confirmation and narrow overclocking scope constrain broader significance.
