Win7 is currently the most used OS, second is XP. You dont think over the next year with the huge drop in dx11 cards that people wont go to dx11?

ANyway my point is that not many people use dx10 as vista is a minority os, and win7 users use dx9 if dx11 is not available in the game because DX10 was not widely adopted.
Also xp only uses 9 so...

Btw what you said is not what I said (or meant) DX9>DX10 DX11>DX10
DX9>DX11. This will shift decisivly to DX11 because nvidia and ati have discontinued there dx10 lines, nvidia is only makine gf110 chips now (500 series).

!!!Your graph is from may 2010, that 5% is 6 months out of date!!!

mate, DX10 will work fine on win7....I play ROF (DX9) on win7 64bit no probs....for smooth gameplay with all the eye candy from DX11 there would be a huge performance drop for most players....

I never said dx10 doesnt work on win7. I said few games used dx10 because it was a performance hog, hard to program for and the only dif was in the lighting effects. DX11 performes better then dx10 for multi core pcs. If enable features like tesselation etc yes its slower, but a hell of alot faster then doing the equivalent on dx10 which would be unplayable.

HOLY CRAP! I'm going to buy you a plane ticket to Moscow! Someone has to warn Oleg that his game is unplayable before it ships!

What? Have you ever programmed in DX before? Because what you're saying makes no sense.

It makes sense to people who know about how the engines function. So I dont have to type it all out (and as while I have modeling experience in Maya, I have only done basic programming), why not use google?

Simply put in general, DX10 was a new pipeline/system that people had to learn but gave little-no benefits. DX11 is a upgraded version but its far more efficient, has far better features and is easier to work with/program. In fact DX10 originally was meant to be what is now DX11 but I believe they released it early to coinside with Vista.

Sorry should have selected only the text that I was referring too.

I code for a living but program in DX as a side hobby, and in terms of difficulty, the changes I've had to do to my code was minimal.

I can understand it being difficult for full blown development teams to modify an existing graphics engine or create an entirely new one but that is more of a man power / cost issue. If you structure your code properly from the start, the API calls you make from your code should be invisible to the operating system, i.e. I write a function to pixel on the screen, my code doesn't care what DX version is installed on the PC or what DX version the graphics card can use, the code automatically calls the appropriate DLLs to draw that pixel.
