When did you last use PCSX2? Version 2.0 that came out almost a year ago made it much, much better than it was in the past.
It's been about a year ago - but since you mentioned it I gave it a shot this week.
I see a setting for latency now (which by default is set to 2 frames, so way worse than actual ps2 - but presumably modern hw can keep up with performance well enough to be useable at lower settings, but haven't tested it yet).
Also finally having a useable controller setup (this used to be really broken) and support for supersampling etc.
Anyway - to the test:
Of the 6 games I tried (5 that have historically not been great) 2 are now - about 80%? accurate in hardware mode - which is an improvement from before(especially seeing volume shadows work in 2 - hats off to the devs to finally get this right), but you know - there's still jank. Third one is still quite bad - some of the graphical features are fixed, but there's new ones, including broken force feedback control etc.
Fourth one used to perform like crap but it rendered correct - now rendering is completely broken.
Fifth also never rendered correct before, now at least the opening scenes look fine, and it performs decently.
Sixth has video playback issues and some effects that I think used to render fine are now wrong.
I didn't have the time to search for hacks yet (although from experience - I think all but maybe the 4th game won't get any better - that one I could see maybe having some FP setting that glitches out).
Also VSync refused to work on any of the games (not sure if it's something in the emulator build or drivers or whatever) - this is a new issue, but it's likely not emulation related since it's just broken atm.
TLDR - yes I see progress (definitely UX has been massively improved as well as handling of certain things) but emulation itself is still glitchy, with compatibility issues.
But I guess the progress here at least gives hope - 2010-2020 was basically stuck with no meaningful change, so this is good to see.
