Run games with different graphic backends

[GeoMan]

Is it possible to run some games with a different graphic backend? Even through a command line?

Some games run better with DX9, others with OpenGL, but even if i manually set different backends to individual game settings, they all revert to the default i have setup in PPSSPP.

No, currently that's a global setting, since PPSSPP can't switch at runtime. We could of course add a command line argument.

If you're on Windows, you'll hopefully soon find that pretty much all games run best with D3D 11. Some issues left to fix before we reach that point though.

For DX11: Unfortunately i am on Win7/64...

Command line for changing backends is:

Code:

--graphics=

which takes one of the listed parameters after equation sign:

Code:

gles
directx9
software
//edit: in new versions on supported hardware/OS the following can also be used:
vulkan
directx11

So it would look like for example:

Code:

PPSSPPWindows64.exe --graphics=gles

using this will run ppsspp with selected backend, that's all, so it's not really faster than switching it from ui, but if you also launch the games from commandline(just use path to the game as last argument), you can just make a shortcut per game or use it from some frontend/launcher, there's lots of those in the net.
Some other commandline options are useful for that stuff like:

Code:

--fullscreen
--escape-exit

example use:

Code:

PPSSPPWindows64.exe --graphics=gles --fullscreen --escape-exit X:\mygame\mygame.PBP

would run mygame.PBP in fullscreen, using OpenGL backend and pressing esc would exit the emulator.

Thanks!
