Increasing the performance

Talking about a better cpu: Intel released a unlocked haswell dual core (Pentium g3258) for like 70 dollars. Would be an amazing cpu for emulation if you are on a tight budget. I don't know how many cores rpcs3 uses, though.

Running just Disgaea 3 I would say at least a quad core with hyperthreading would be a good start Not that any CPU would be fast enough.

I looked it up and apparently rpcs3 can use up to 9 cores.. pretty sick.. all other emulators i know only use 2 or 3 at most. So in that case the g3258 wouldn't be that good indeed.

Pretty much there is no consumer CPU out there that can run rpcs3 with some heavier games (not arkedo/frogger, but at leas 3D) at decent speed.
Not that rpcs3 can emulate much of such games.
But in a few years (hopefully) some fully-playable (completable) complex games will appear and with other optimizations + newer CPUs it might be possible.

I´m pretty sure Intels Skylake(with DDR4 compatibility) will do the job.

What was the plan for DirectX? (forgot that over the time....) If the plan is to implement a DirectX method, is DirectX12 considered?
