The consoles playing same bf4 at 60fps on slow jaguar cores in a first person shooter - not even batch limited like a rts- shows how extreme the gains can be with mantle.
If anything is hard data thats it imho.
Go see the mantle execution model and presentation; There is a far better paralalization. That explains why the consoles can work fine even though they are not batch limited like a rts.
The crazy thing is as said before, we can even have situations in rts games where a slow quad core kaveri can play a game using mantle and an highend cpu on 780 can not do the same. Because of dx.
We are talking differences of a factor 30 or 3000%. People comming with 20% or 50% difference for lacking dx11 optimization should compare the 20-50% to 3000%.
I want the 3000%. Because it can give me completely new gaming experience. To be frank i dont care about ms or nv or amd financials or the feelings of some brand loyalists. I want some freaking new games that kick some a.. instead of the same stuff year after year. I want Dune e 3 in uber 3d with trueaudio created by a modern Mozart. Thousands of configurable units in a huge online war !!!!!
Unfortunately we will probably tave to wait for gen2 mantle engines to provide that. Lol.
