A year ago you would be seen as a lunatic trying to play a commercial game through a ps4 emulator, a system that's still very recent tech wise despite the 10 year age. Just months ago ShadPS4 wasn't even the best PS4 emulator, all things PS4 emulation was still in its infancy. A breakthrough happened and in mere months and through sheer will, Bloodborne is mostly playable today, this speed is unheard of when it comes to Playstation emulation.
This is to say, and I don't mean it in an antagonistic way, but you gotta keep your expectations in check when it comes to these things. Despite the advanvements of ShadPS4 it's still early days, believe it or not, and it's remarkable it even progressed this much in such little time. I'd give it a few more years for the emulator to get to the level of something like RPCS3 for example.
These things take time. PCSX2 is more than 20 years old and only a couple years ago it stopped being a broken mess that barely worked with the Qt overhaul. RPCS3 still has bad reputation generally because it was slow for so many years that people don't realize how better its gotten now. Proper PS4 emulation should theoritically develop faster than these two, but not to the point that you can play different AAA games this early on.
