With Directx 12 coming with Windows 10 later this year, and early tests showing a lot of real potential for performance improvements, I would hope the Dev team is working to update the Dreamworld engine to take advantage of Directx 12.
Even now, 7 years after launch, AoC is too demanding for most average off-the-shelf PC's to run smoothly, cutting out a lot of potential subscribers.
I can see some clear advantages to the bottom line here if you guys get on the bandwagon:
1) Coding the engine for Directx 12 should yield substantial fps improvements, meaning also that more 'average' PC's can play the game reasonably well - translating into more ppl who try it and don't quit due to poor fps.
2) Being able to say, when Windows 10 arrives, that Age of Conan (and TSW) is ready to take advantage of it and deliver improved performance is a huge *marketing* tool to draw in ppl.
Now, what I suspect will happen is, they will wait for Windows 10 and Directx 12 and just watch how things develop, and then possibly decide to start the process of updating the Dreamworld engine and maybe deliver it late next year(if not later). While this is better than doing nothing, Funcom completely loses the opportunity to get in front of the curve where the big benefits are in terms of pulling in new subscribers, letting everyone know they are staying up-to-date with technology advances in this area. Since the engine is used for both AoC and TSW of course, the benefits are equally broad.
Anyway, my 2 bits on the matter.
