Vulkan requires a “arms-on” approach to graphics development; there’s usually extra work concerned in the improvement of things. But the result is a decrease CPU overhead, which typically increases general performance. That’s massively helpful for platforms like PPSSPP, the place every freed-up processing cycle can lead to speedups on troublesome-to-emulate games.
