Weird textures playing Final Fantasy XII on the PSCX2 / LRPS2 core

[xonapej928]

I am seeing strange textures, often around the hair and face, but in other areas as well when playing Final Fantasy XII on the PCSX2 / LRPS2 core. How do I fix this?

Attached a log just in case it helps:

Unfortunately, there’s not much to be done about that sort of thing in the current LRPS2 core. That is, most of that sort of thing is fixed upstream by switching to the software renderer, which isn’t hooked up in the current core. There’s a semi-updated WIP core that does have it but I don’t have any Windows builds for it, only linux.

I see, thank you for taking the time to explain!

Leaving this for posterity, but a big part of why I use RetroArch in the first place is just for the shaders, so someone on Reddit recommended using ReShade or the Windowcast core as an alternative, which I am going to try.
