Busy Building whilie I wait

I´ll re sum and show it easy as is possible :

-Having the game written in DX9 only and then have to jump to DX10/11 = Bad thing.

-Having the game written in DX10 only and then have to jump to DX11 = Not bad thing because DX11 is a upper set of DX10 so you just should update some strings in the render pipeline.

-Having the game written in DX9 and DX10 and then have to jump to DX11 = Not a bad thing if you don't have the game textures and performance balanced to show good IQ and performance in DX9.

If you have the game balanced to show good Image Quality and performance in DX9 then you are holding back the DX10/11 possibilities.

You´ll have to adjust the textures to the new DX10/11 lighting and project a better use of performance in the map details = more work.
