Of course, running the Folding@Home command line client isn't supposed to take away system resources from more important processes. The client itself is tagged with a low process priority when running in Windows, so just about any other system process should have first dibs on system resources. Folding@Home should only use CPU cycles your system would otherwise leave fallow, which means there should be no perceptible impact on performance when running the Folding client.
Despite that fact, some businesses may fear a loss of computational productivity, and gamers may want to avoid a potentially deadly drop in frame rates, just to be safe. Rather than simply trusting that Folding@Home doesn't impact system performance or assuming that running the client will slow things down, we've run the client through a gauntlet of tests to set the record straight, one way or another. Read on to find out just how much of an impact, if any, running Folding@Home will have on system performance.
