This is a thing now, apparently. Compatibility is still low. RPCS3 - rpcs3.net ESX - esxemulator.com My system is: i4570 (3.2 GHz "Haswell") & GTX 770 I tried Project DIVA F US version last night with RPCS3 and it did work, but I was getting 15 fps average which isn't enough to enjoy the game. Others with similar specs got better results - the 30 fps the game is programmed to run at - and I have no idea why. I think maybe more development is needed. For my very basic troubleshooting attempt, I opened resource monitor and saw CPU running at max boost clock (3.45 GHz) but utilization around 45% on all cores and the system still responsive while it was running. So maybe it's CPU limited, I don't know. GTX 770 is a bit of a rare card and it didn't work with RPCS3's "Vulkan" rendered, which others used to get better fps. I will give ESX a try tonight.
