X-bit labs yesterday posted a news-story in regards of alleged application specific optimizations implemented into XGI Reactor drivers. Today the company denied the existence of application-specific optimisations.

“The .exe files listed in xrvkp.sys are only for developers’ analysis during beginning of the developing cycle. We left the file names in xrvkp.sys and have not removed since then. We will take more intensive care to avoid confusion in the future and will fix that in the next driver release,” commented Chris Lin of XGI.

Furthermore, there is remark from editors of Volari Gamers web-site.

“I have tried to rename the .exe files of benchmarks in order to see if there was any change of performance with such manipulation. Whereas NVIDIA drivers see their performance decrease with such a simple name change, I have seen no change in [XGI] performance when renaming the files,” said Xglider in his Volari V8 Ultra preview.

Observers have found names of executable files in xvrkp.sys files from the XGI Reactor driver-set. The purpose of having such files mentioned in the drivers was not clear, but since there were a number of industrial benchmarks among the titles declared, there was a suppose that XGI Reactor drivers activate special presets to improve performance or image quality in such applications. The suspicions, however, were denied by XGI.

X-bit labs will conduct an independent analysis of XGI Volari hardware and drivers in future.
