Ppsspp: [GE Emulation] [Android/OpenGL] Harvest Moon Boy and Girl Poor Performance On Snapdragon 430 CPU Adreno 505 GPU

[Gamemulatorer]

This game is smooth on my Mali-450 GPU phone default settings but lag on Adreno 505 GPU phone of my friend.

I already tried ppsspp v1.9.4 playstore also tried ppsspp latest git build but still lag.

@Emulatorer what adreno 505 device are you using?

[hrydgard]

505 might simply be a very slow GPU? It's not clear there's anything we can do here. Does Vulkan make a difference, if you can run that on 505?

[Gamemulatorer]

@hrydgard no adreno 505 GPU is powerful compare to mali 450 GPU.

Here's the full specs of the phone:

Specs Of Cloudfone Next Lite

SCREEN • 5.0-inch FHD IPS LCD Display (1080 x 1920 Pixels, 441 ppi) with 2.5D Arc Glass
OS • Android 6.0 Marshmallow
CHIPSET • Qualcomm Snapdragon 430
CPU • 1.4GHz Octa Core Cortex-A53
GPU • Adreno 505
RAM • 3 GB

@Panderner Snapdragon 430 Adreno 505 is 64bit while MediaTek mt6592 Mali 450 is only 32bit.

What about your GPU settings? Rendering resolution can significantly affect performance.

[Panderner]

@Emulatorer what Mali-450 device are you using?

[Gamemulatorer]

@leopard20 His using default settings of ppsspp

It could be down to the 1.7 Ghz of the other device? Even if it's graphics limited, the GPU driver could be performing better with the 1.7 Ghz even on a weaker GPU.

@unknownbrackets no my phone mt6592 is only 1.36GHz while snapdragon 430 is 1.4GHz

Tekken6, Untold Stories, Crash Mind Over Mutant, Power Stone Collection and Brave Stories are running full speed frameskiping off on Snapdragon 430 while in my MT6592 I need to use frameskiping x1 and reduce the rendering resolution.

[Gamemulatorer]

@unknownbrackets didn't find in my GE Dump why this game is lag on Snapdragon 430?

[unknownbrackets]

It renders at 320x240, then does a reverse-subtract blend from a solid color, then stretches that to the screen. It doesn't draw all the efficiently (it starts with far away things), but it's not that many draw calls.

Not really seeing anything that should majorly impact performance.

Brave Story may leverage Mali features to blend more efficiently in some places. Not sure of anything else for the others.

Um yes Harvest Moon: Boy & Girl is a port of a PS1 game Harvest Moon: Back to Nature but added female protagonist, The original game renders 320x240.

@unknownbrackets I also tested this game on my tablet with Mali-T720 GPU 1.3GHz CPU clockspeed in it's running at FULL SPEED...

[Gamemulatorer]

Sad I don't have a phone with Snapdragon 435+ cpu to test if this game is lag :(

Maybe this game is only lag on Snapdragon 400 series 🤔

[Gamemulatorer]

@unknownbrackets I found out that the lag only happen when characters are moving but during dialogue this game is smooth there's must be something wrong 🤔

There's nothing wrong, this game modifies textures when character is walking, it also loads new stuff when you walk around, movement will always be heavier than standing still doing nothing.

[Gamemulatorer]

@LunaMoo then why this lag doesn't happen on my ancient phone with Mali450 gpu?

[LunaMoo]

Maybe the other person is using texture scaling. This would kill performance on most or all phones, even vulkan's hardware texture scaling since this game as I said modifies textures when you're walking and they have to be processed again.

Edit: also adreno 505 is bottom end of it's line, middle digit means power. 0 is the worst.

[Gamemulatorer]

It's kinda werid that Snapdragon 430 out performance by an old mali 450 gpu
🤣

Performance on Android is sometimes very unpredictable due to the many combinations of hardware, OS and driver and thermal management, and it's not uncommon that older devices outperform newer ones. And given that indeed 505 seems like a very weak Adreno, I don't think there's much to do here. Switch rendering to 1x resolution, might be enough to get it to better speeds.

[Gamemulatorer]

It is sad that this issue is close and not added to future milestone 😢
@hrydgard I already did that changing rendering resolution to x1 doesn't help enabling speedup option doesn't also help.

Snapdragon 430 Adreno 505 can run the games
that I mention here https://github.com/hrydgard/ppsspp/issues/12824#issuecomment-613824225 at full speed so why this game is only lag 🤷
but running smooth on the weak old mt6592 mali450 GPU 😞

[hrydgard]

Because I don't know of any way we could fix it.

[Gamemulatorer]

Just putting here
recording.ppdmp.zip The GE Dump from my phone (MALI-450)
hoping someday, someone can fixed this issue :)

[leopard20]

If you're sure that your friend's phone is more powerful and it's underperforming, then it's probably related to some software issue (bad governor settings, bad drivers, etc.) I think the game (and accordingly the emulator) is doing something that the Adreno 505 driver can't handle efficiently.

[Gamemulatorer]

@leopard20 maybe your right..
