19	help
20	  The VRAM of the G200 is mapped with Write-Combine to improve
21	  performances. This can interfere with real-time tasks; even if they
22	  are running on other CPU cores than the graphics output.
23	  Enable this option only if you run realtime tasks on a server with a
24	  Matrox G200.
