Final Fantasy XV

Returned to the fable FFXV only to find its still in an horrible state as it was a few years ago when I tried to play it so, I once again turned to SpecialK to help out with my issues .
What’s the best version for the game ?
Also, is there a guide on what settings help the most, as I’m quite clueless about most of it, but using a random guide from steam I found the measure residency crashes the game (no idea what it suppose to do) .
Can I have some guidance please I’m tired of crashes and glitches , but I like the game…
Thank you
