Martin Malik from www.hwinfo.com has found a file in Reactor drivers for XGI Volari VPUs that refers to numerous game and benchmark titles. The purpose of the file is not clear, but we may suggest that the file is made with the purpose to activate specifically created presets for every game or benchmark software used.

Currently the file xrvkp.sys contains the following executable files:

Moreover the driver:

- seems to modify Direct3D settings in registry (3D.Table, 3D.Func)
- seems also to enable Write Combining via MTRRs

The guys at www.hardware.fr site have done some tests and confirm the findings:
