Ppsspp: [Android][OpenGL]Phineas & Ferb can't reach 20/20 FPS - 1.10.2

[EX-e-LD]

Hi,me again.I went to play Phineas & Ferb - Across the 2nd Dimension,and game can't reach 20/20 FPS.I tried everything (I/O timing methods,buffered/non-buffered rendering,1x Rendering Resolution)However,i noticed that game looks like really bad rendered at Buffered Rendering,while looks better and performes better at Non-buffered rendering

Buffered Rendering:

Non-buffered Rendering:

All images were taken with 2x Rendering Resolution

TIA

On the latest git build of ppsspp the screen is flickering in this game and I also notice it on other game(s) intro video

@EX-e-LD what device are you using?

As always,Honor 9S.I will now test on my PC.

[EX-e-LD]

This game runs fine on Direct3D 11,this is sure OpenGL bug,i will provide GE Dump tomorrow.

The game works fine for me running on Realme C2 on 3x Resolution

@Panderner the screen is not flickering on your phone using the latest git build of ppsspp on opengl backend!?

[Panderner]

but @Gamemulatorer what device are you using?

[Gamemulatorer]

but @Gamemulatorer what device are you using?

Just answer my question if it's flickering on your phone using the latest git build of ppsspp.

The stable version 1.10.3 has no screen flickering on my phone w/ opengl 2.0

No screen flickering at all on my phone in latest git build but Tell me @Gamemulatorer what phone are you using?

[EX-e-LD]

No flickering here as well,but lag is same no matter the option.

It's weird that your phone is more powerful than mine but can't reach 20/20 FPS 99.9% Speed lol 😅✌

Im using PPSSPP v1.10.3-59-git buildbot apk (no screen flickering)

Phone Specs

                     mali-450 gpu
                     1.36GHz cpu clock speed
                     2gb of RAM
                     Octacore cpu

Try the latest git build first before you say that https://buildbot.orphis.net/ppsspp/

[EX-e-LD]

I will,give me a second,and i will report here.

[Panderner]

@Gamemulatorer what CPU are you using?

[EX-e-LD]

Nope,still same.Damm,gotta make GE Dump.

[Gamemulatorer]

Nope,still same.Damm,gotta make GE Dump.

Still lag? can't reach 20fps using the latest git build of ppsspp? if yes, then it's your phone issue not ppsspp.

because my low specs phone can reach 20fps & 99%speed.

[EX-e-LD]

Bugs can occur on certain devices,just search GitHub with term PowerVR,you would be surprised.I don't think phone can cause this way of handling.

Read here https://github.com/hrydgard/ppsspp/issues/12824#issuecomment-614069461 so you could understand that different games in psp behave different on every android gpu phones

[EX-e-LD]

Your opinion, @hrydgard ?

[EX-e-LD]

Here is my GE Dump:

Using your GE dump I still got 30fps

[EX-e-LD]

30?20 is default.And what do you mean by "using" frame dump?Please explain

TIA

[hrydgard]

You can just open them in PPSSPP, but measuring performance from running the GE dump will not give you the whole picture as only the rendering is performed, not the CPU emulation.

[EX-e-LD]

I get it.So what about the "bug" here?Is it my issue or emulator's issue?

TIA

@EX-e-LD try another game with 20/20fps like #13040 and see if your phone can reach it :)

[Gamemulatorer]

I try this game on another low specs android device
the soc is snapdragon 430 adreno 505 but it can reach the game to it's maximum fps of 20/20.

So this issue maybe is your phone fault not ppsspp imoo

[Panderner]

or maybe it's related refresh rate issue

[EX-e-LD]

Sorry,but i'll wait developer's rant on this,if i get one.

[Gamemulatorer]

Sorry,but i'll wait developer's rant on this,if i get one.

Better try other game(s) with 20fps limit like Beowulf #13040 or try MGSPW also have 20fps limit and check if your phone can reach it maximum fps.
If not your phone has the issue not ppsspp.

So what if it can run properly?

If those 2 games I mentioned earlier can run at maximum fps of 20 on your phone, then this only game P&P have problem not your phone.

Hope you get my point here I'm not really good in english :(✌

Emulator issue?If i understood correctly.I will keep it for chance developer will see it.Thanks anyways,i appreciate it.

[Gamemulatorer]

This game running smooth on a 1gb ram, quad-core CPU w/ Mali400 GPU but the annoying screen flickering issue on opengl es 2 made me quit using PPSSPP buildbot 😅
