Program for Direct X 9 and Direct X 10 lol duh (Score 1)

It's actually easier to just program for Direct X 9 and add enhancements for Direct X 10 ... infact this is leaps and bounds easier than reprogramming for Open GL. ... infact... u dont REALLY have to program for Direct X 10 if you want to lets say, Boycott Vista / DX10 , then programming for Direct X 9 will still reach the massive audience ... and Open GL is still a downgrade compared to DX9.
