As i already posted before, i had this problem too. Since i had enough of it to be always behind with ongoing DX11 problems , instead of playing and just having fun, I yesterday bought second hand DX11 card, which i found in the internet for $150. Btw it's a GTX 660 TGT ULTRA CHARGED and i have to admit it was every penny worth! Now i am able to play all the games without any problems on max detail. And i still use my old ASUS motherboard with an Q6600 quad core processor on it. I just changed the GFX card and set the graphics to max, running the game smoothly with antialising in full 1920x1200! I know it doesn't help to get your TITANFALL running again but i just want to say, that sooner or later many new great games will use DX11 only and i realized that it's not always a reason to complain about changes like this. Consider we are in the middle of a new DX-aera, where games use newer techniques to achieve faster results. Of course TITANFALL didn't really used DX11 effects, instead of the only antialising feature, but hey - see it like that, we are PC users, we love to play games on the PC, rather than on a console and why not investing a bit of our money, which we normaly throw out for unecessary things, instead for something we really enjoy to do?! And that's playing games on our precious PC ^^ And what will you do when GTA 5 will be out for PC this fall? You really think it will be playable on our DX10.1 cards? I really enjoyed my GTX275 for many great moments and i will keep it as a spare card, but i am really happy to be able to play all the new games, which will be released in the next couple of years, like DESTINY or THE DEVISION, GTA 5 and so on.
Just my new point of view of solving especially this DX issues, instead of sitting hours to repair something that doesn't want to be repaired. :/
Of course i am very interested to hear your opinions! Let me know what you think!
