Tales of phantasia slow issue #8538 try ppsspp latest git build from here https://buildbot.orphis.net/ppsspp/

[hrydgard]

Getting somewhat different problems on Star Ocean (character not behind furniture, as if stencil wasn't on or zero) but yeah, it's not working right. Seems like another driver bug, sigh (or if we somehow end up not storing or loading stencil with DONT_CARE in a render pass...)

[hrydgard]

When that build is ready, please check if it fixes your problems.

[asbel123]

Did this used to work in v1.9.4? Or an older version? It'd help to figure out when it broke, if so.

Could you create a frame dump, at any scene that's missing a background? Doesn't matter if the frame dump is created on PC or Android.

@asbel123 the devs asking for a ge dump not for a picture 🤦

[hrydgard]

So there's obviously some driver bug with regards to stencil testing here. I just got an idea for a possible workaround, but which will have a small performance penalty, just committed it.

If this works I'll try to reproduce the bug independently and report it to ARM for fixing...

[hrydgard]

@asbel123 Can you try again with the latest build from https://buildbot.orphis.net/ppsspp/ ?

[hrydgard]

@asbel123 Could you please re-test as described in my last post above?

[hrydgard]

Gonna leave this hack in place and postpone further work to after 1.10.

Any update and ge dump?

[unknownbrackets]

Maybe we should remove the pixel rounding if it's not actually helping. But maybe it is and that's why there haven't been further reports...

@asbel123 any news?

Found new issue look at the grass
1X resolution

2X resolution

software

Tales of Phantasia - Narikiri Dungeon X.zip

[ghost]

Tales Of Phantasia (ULJS0079)
No graphics glitch on my phone.

[hrydgard]

@Gamemulatorer Is that one related to Auto Max Quality texture filtering?

No

Just noticed that this issue is cause by auto max quality.

X1 PSP RESOLUTION

Increasing PSP RESOLUTION make the graphics issue disappear.

10X PSP RESOLUTION

[unknownbrackets]

FWIW, that's Narikiri Dungeon X, which is a remake of a GBC game, and the initial screenshots in this issue were for Tales of Phantasia X, a remake of a SNES game which is included with Narikiri Dungeon X. There's also Tales of Phantasia Full Voice Edition, which is a predecessor of sorts to Tales of Phantasia X. Ah, the many remakes of Tales...

Anyway, the grass issue is therefore definitely #14986. Doesn't seem related to the initial issue of missing background graphics in battles.

Is this issue for Cross Edition?
The title is ambiguous.

[ghost]

This might be fix using the recently build? @asbel123?

everything looks normal fine.
i don't have version Cross Edition.

I think this one was solved by the depth/stencil workaround (writing Z in the fragment shader even though we don't really want to change it) quite a while back. I'm closing.
