@SilentMRG can you still repruduce?

@SilentMRG can you still repruduce?

To be honest, I haven't tested it yet. I'm using version 1.13, and when I have some time to spare I'll update and retest this title. At the moment, I'm out of time. Thanks for asking!

Edit: However, if you are referring to version 1.13, yes, the error still occurs. I don't know if the error occurs in the current version 1.13.1 or other builds of version 1.13.

Any fixes would be in the latest git build - no retroactive changes are made to released versions. This is known broken on v1.13.1 and will always be broken on that version. However, recent git builds may have improved things.

This issue I can only reproduce on mali gpu's adreno gpu's cannot reproduce this.

can you still repruduce?

I just tested on version 1.13.2 and the pseudo CRT filter is still there. The only good thing I noticed is that there was a noticeable performance gain and I didn't need to activate frame skipping.

Can you test the latest build https://buildbot.orphis.net/ppsspp/index.php?m=fulllist

[SilentMRG]

Can you test the latest build

Apparently in the build: v1.13.2-1013-gc80cc1e87 - 2022-09-17 23:35:15

The pseudo CRT filter has been fixed!!! \o/ HOWEVER, the frame rate is the opposite of version 1.13.2, to give you an idea, it was around 15 fps. And not even skipping 8 frames solved it. XD

What is your device?

[hrydgard]

Such a slowdown is surprising, gonna need to investigate that.

[SilentMRG]

What is your device?

Windows 7 Ultimate 64 bit i5 2.67 GHz 4 GB DDR3 Intel HD Graphics 1000 It's an 11-year-old Laptop Grandpa! XD

And yes... I know it's a potato device, but I think the problem, in this case, is not on my side.

[hrydgard]

No, I don't think so either.

Changing from skip buffer to buffer rendering causes this. ULUS10345.ppdmp.zip

[SilentMRG]

On Windows; version 1.14 (except the backend, all settings are at default); using DirectX 9, I got this...

All these filters and lines come up in some parts of the stages and then go away.

These lines are intermittent and sometimes there are horizontal lines longer than this, and they just going up and down.

I confess that I liked the lightning effect! It even looks like a high definition effect. XD

@SilentMRG how about the performance?

[SilentMRG]

how about the performance?

FPS goes from 30 to 45/60, and drops to 30 and back to 45.

What is the performance now using recently build PPSSPP?

[ghost]

Closing this performance is acceptable on my phone :)

FPS goes from 30 to 45/60, and drops to 30 and back to 45.

I discover that if you change emulated psp cpu clock speed to 666mhz this game will lock to 60fps.
