Enhancement -PGXP settings, disable PGXP depth buffer, this feature has very low compatibility and requires fine tune adjustment for some games.

Best to just leave it off

For PGXP settings it's generally safe to enable Geometry correction, Culling correction and Texture correction.

The rest aren't really needed or generally safe.
Preserve Projection Precision saves some performance at the costs of precision and can break certain things like life bars or loading bars.

Depth Buffer even further corrects polygons from colliding with one another but it's not generally safe and requires fine tuning for some games in advanced settings.

CPU mode offers even better precision for all the PGXP features but it's very CPU demanding and generally the difference is minimal, best to leave it off.

For that one you have to turn off PGXP geometry correction or Culling correction, don't remember which.

PGXP is a neat feature fixing some of the biggest flaw of the ps1 but it's not a flawless feature especially with games that have their own form of corrections function, for example the Spyro games have their own texture correction which then is broken by PGXP texture correction glitching near textures.
