Kombustor is based on Furmark, a stress test famous in the enthusiast community for frying videocards alive in its quest to probe GPUs’ outer limits. Kombustor’s fur test is anything but soft on your GPU. It’s a benchmark called Kombustor, and it’s aptly named.
Hardware manufacturer MSI, creators of Afterburner, have conjured up a way to make your overachieving videocard sweat for a change. This and other inconsistencies mean you need to go beyond FRAPS and your favorite game when looking at overclocked GPU stability. Your clock-cooked Radeon may sneer at Skyrim on max settings, but those same speeds can make your computer crash and burn when playing Witcher II. Pushing up memory and core speeds on video hardware has consequences, not all of them readily apparent.
