d00d get ur facts right
OpenGL has got nothin 2 do wit d
Open Source movement
d
OPEN stands 4
OPEN STANDARDS
OpenGL Licensing Programs
as 4 choosing betn DX and OpenGL, DX has been optimised 4 performance by MS, so any game developed with DX API will perform well on Win platform whereas in OpenGL u willl have to port ur codes 2 make it win-compatible, thereby increasin devp time [read more time to market] , devp cost[read higher cost of titles, reduced margins of operations et all]
so if a devp know dat it will make only win-based appz DX is logical choice
