Guide:- Maximizing the performance of PPSSPP on your Android/Windows device.

[solarmystic]

Updated the guide to reflect the release of 0.9.

Rough Changelog:-

-Screenshots were retaken from 0.9's NewUI, since the OldUI has been stripped completely of the emulator it seems.

-Changed the names of a few options which were altered in 0.9.

(Off I go! Only came back for a bit to update the perf guide)

i want to ask
i'm used ppsspp-v0.9.1-17-g1330d5c-windows-x86
when i opened ppsspp.exe there is announcement ppsspp has stop working
why?
i'm used win7 32 bit

this's my GPU

Your GPU doesn't have official OpenGL 2.0 drivers for Windows 7, which is why PPSSPP stopped working.

PPSSPP needs a graphics card that supports OGL 2.0 at the minimum to work. For Intel, that means you need at least the HD2000/3000/4000 for half decent performance.

I'm afraid you're out of luck for that graphics card.

How about I/O on thread option? What different when enable disable?

[GuilhermeGS2]

I also want to know what is I/O on thread.

[cyclonmaster]

I did some reading here and there, some says that on android if the dpi is reduced, the gaming performance can increase. Is it true? I wonder what effect does it can make for ppsspp?

I'm not solarmystic, but I did some independant testing of the function, and the difference in performance is very minimal on my Pentium D machine, so it doesn't really matter either way, unless you have a game that needs it to work.

An example would be Dead or Alive: Paradise, which needs I/O on thread option to boot up and work properly.

On Android, make any difference?

Quote:13. Turn OFF Vsync. (Will cause tearing in the image, but gives a performance boost) -Windows only, since Android devices have Vsync always on-

I believe you can also disable vsync on android. I did it using pimp my rom application.

Hello again folks. I'm back for good this time around, I just came back from my vacation.

@GuilhermeGS2

The only reason why I haven't added the I/O on thread option to the performance guide, is exactly what bonquacks said.

On my Core 2 Duo machine, the performance difference was almost negligible. It was actually slower in certain games. (-2,-3 VPS, I still have the older framerate counters on my special PPSSPP build).

@cyclonmaster

Does that require a rooted Android device? If it does, it may not be so useful for those who don't want to root their devices.

[GuilhermeGS2]

Thanks! So, I think I will disable it.

Updated guide to account for Vsync functionality that has been fixed in v0.9.1-76-g955ad2a and beyond.

I/O is related to the way it read file or interact with file and information (I think ahah)

These two experimental option break project diva (the other one... I don't remember the name of it)

Thanks for this guide. Now i can play almost game on ppsspp with full speed. Just want to share something . I don't know if someone has said this before. For anyone who want gain little speed and smoothness when play ppsspp on android devices, try enable setting at developer option and check 'disable hardware overlays' and 'force gpu rendering' (You can check either one or both). It basically forcing every single app's drawing to be rendered by the GPU instead of cpu. As i know ppsspp is heavily depends on cpu. When you check of this two option, ppsspp now will gain little extra cpu power.

Pro - would be smoother drawing in certain apps where HW acceleration is not utilized.
Con - would be decrease in battery life, and possibly increase in overall phone temperature.
- certain apps may crashed by enable this option.

FYI, i have been playing Danganronpa on ppsspp android. Of course we have to used 'read framebuffers to memory(cpu)) mode which is essential to play danganronpa. Before i check this two option the speed is roughly in 16-24/30. After i enable it, the speed is increase in 28-31/30.

However i not guarantee this tips is working on all android devices as it also depends on cpu and gpu specs.

Update 08-27-2013:

Well thats weird . Now i know why i can play danganronpa with 'Read Framebuffers To Memory(CPU)' mode smoothly. Here what i thought . While i playing danganronpa then leave the game(not closed) to used any other applications and then back to draganronpa, the rendering mode is automatically switch to 'Read Framebuffers To Memory(GPU)' or 'Buffered rendering' mode eventhough on screen, it still display rendering mode is 'Read Framebuffers To Memory(CPU)'. I said that because i can't interact with other characters in danganronpa.

Unfortunately this tips may actually not work but you can try playing with that setting. Maybe you can get 2-5% speed thats why i think .

Good!!
Now I dont have to force vsync when playing mhp3rd
----
Hey guys can i play mhp3rd hd with 60 fps but the speed is not >100% ??
when i hit 60 fps my speed is 200% & How to reduce the speed to 100% normal with 60 fps cap??
