im using the release candidate 5.0 version right now. The 4.0 release version was giving me low FPS in Twin Snakes, upgrading to the 5.0 version nearly doubled that, i guess it makes better usage of DX12's API or something but the difference was huge. Same for PCSX, im getting a lot better frame rates in the newer development versions. Even on my modest laptop PS2 and GC emulation is working 100% now, maybe not at 4X native but its good enough that i won't need to use the PS3's PS2 emulator etc anymore.
