[BParks21]

Game or games this happens in

ULUS10107 Valkyrie Profile Lenneth

What area of the game

Any traversable area with different rooms/locations that require loading (dungeons & towns) mainly.

Speed seen in PPSSPP

Drops to 90% speed with vulkan, around 94% with D3D9/11 & remains at 100% with ogl.

GE frame capture and debug statistics

No response

Platform

Windows

Mobile phone model or graphics card

GTX 1080ti

PPSSPP version affected

v1.12.3-889-g50350e13a

Last working version

Not sure

Graphics backend (3D API)

Vulkan, D3D11/9

Any other notes or things you've tried

Game drops to 90% game speed for no reason and audio will hiccup. Even at default settings using vulkan and D3D9/11. Not sure what's going on ogl is fine. Also happens with latest libretro core.

Checklist

• Test in the latest git build in case it's already fixed.
• Search for other reports of the same issue.
• Try resetting settings or older versions and include if the issue is related.
• Try changing graphics settings to determine if one causes the slowdown.
• Include logs or screenshots of issue.

The problem by description sounds like texture scaling, but can't reproduce on my end with either texture scaling or default settings, at least with PPSSPP proper, not interested in libretro.

Happens with scaling off and native resolution.

is this happened only on recent builds?
if it's you should try to find out the last version that worked full speed

[BParks21]

@LunaMoo What version are you testing?

[LunaMoo]

I tested with fresh copy of v1.12.3-905-g4c095ce06 as well as with my personal build, saw no noticeable difference between backends.

Checking frame graph I can see pretty huge spike in both Vulkan and OGL from decodetex, but I guess my RTX 3060 Ti is faster than GTX 1080 Ti by a decent margin so it's still well within budget to keep running at full speed, weaker hardware would probably see similar drop in OGL as in Vulkan.

@hrydgard Are you able to reproduce? I'll do some testing with older builds.

[BParks21]

Yeah I can't produce this on 1.12.3 stable, vulkan is smooth for this game in the last stable release. Did a clean install of the latest dev build and the issue persists so yeah it's definitely an issue, just have to figure out when it started.

Have you had any luck determining a build this got slower in? Is it any better in the latest git?

[BParks21]

No haven't had a chance to test older builds. It's the same in the latest git.

Try build before #15162

[BParks21]

Ok i will try as soon as I can

[ghost]

This might improve via #15474 or 9b25093

Valkyrie Profile performance is fixed with Vulkan, but now Crisis Core is crashing after the intro logos on Vulkan and D3D11 not Opengl. Not sure if it's related.

Crashing after intro logo is not related to this issue you must create separate issue about that :)

[hrydgard]

I'll take a look at that, might be some bug in the fix.

[hrydgard]

Think it should be working now in -1067.

[BParks21]

Think it should be working now in -1067.

Still crashing to the desktop for me in that version, vulkan and d3d.

[hrydgard]

Hmm, ok. I'll take another look. Got some non-default options enabled, like texture scaling?

[BParks21]

Yes I had xbrz x5 on. Turning it off prevents crashing. Used to work with it on.

[hrydgard]

Thanks, I got the crash to reproduce. Will fix.

[BParks21]

Ok thanks

[hrydgard]

Fixed in the next build. Gonna close this too, since you're reporting that perf seems ok now.
