Nvidia accused of fudging tests

A software maker that specializes in tools for measuring performance of PC components has accused graphics chip giant Nvidia of manipulating test results for its latest graphics chip.

Saratoga, Calif.-based Futuremark on Friday said in a statement that Nvidia tweaked software needed to run its new GeForce FX 5900 processor to distort performance in Futuremark’s 3DMark 03 testing application. Futuremark is one of the leading independent providers of software and services for performing PC “benchmark” tests.

The company said drivers–software files that govern how a component interacts with the rest of the PC–for the new Nvidia chip were altered to detect activity characteristic of a benchmark and adjust performance accordingly.
