In your opinion, I am just wondering if it is still worth (continuing) learning DirectX 9. Or is it time to stop beating a dead horse and move on to DirectX 11.
I know that if I go to DX11, I then lose XP as a target audience (which still has a reasonable market share). But, on the otherhand by the time I get proficient enough in DX11 XP will be even older.
So, what would your advice be? Move on and work with newer tech or keep learning old tech and keep the possibility of a wider audience?
