And also when I overdrive there's a grapics bugs in The 3rd Birthday (Disable Slower Effects is On)
Im using now the latest ppsspp version 1.6
Phone Specs:
Android 5.1
Mali-450
OpenGL

The checkbox can be considered to be "Use graphical bugs for speed". It's expected that there will be graphics bugs when you check the setting.

Which git build was last fast and which was the first one that became slower, when slower effects are allowed (setting unchecked)?

ppsspp 1.6.1

In ppsspp-v1.5.4-931-g9c059a7b6 the game running 20+fps in default settings but in ppsspp-v1.5.4-933-g386c9d4fc the game running only 15+FPS in default settings

This is just a minor issue enable "Disable Slower Effects" speed up the game with a little graphical issue 😃

So that's #10956. Maybe there's a way to detect that it's not needed to to combine depals here, but it makes sense unfortunately that fixing #10951 would make it slower.

As mentioned in #10956 post processing the display lists like we do with Sonic Rivals on Vulkan is probably the only way to fix this properly, which takes some effort.. and we can currently only do it for Vulkan and OpenGL, though I guess PC:s with DX can probably just brute force through it.

@hrydgard I also notice slow-downs in other games as well. They are very small to notice on powerful devices though (S7 equivalents and up)

For the purpose of recombining, it'd be nice to have some better meta information on the draws - ideally, the clut params / palette hash, source framebuf, and area (maybe this can be read from the verts.) That might allow combining automatically in a general case.

At least for 3rd Birthday, that ought to allow combining. In render-to-self cases, I don't know if it can be automatic without detecting the destination pixel area. It's relatively uncommon, though...

Sad to say 3rd birthday still lag when disable slower effects is OFF :(

[hrydgard]

Doing something clever here is too much work, it'll unfortunately have to be like this in 1.8.0.

UPDATE

Using ppsspp v1.8.0 graphics glitches is rarely happens if I enable the "Disable Slower Effects"

[ghost]

Disable Slower Effects in the latest build cannot help speedup this games anymore so I will close this and for the meantime I will use skip buffered rendering for this games
Hoping someday this 2 games will improve performance in buffered rendering :)
The 3rd Birthday Skip Buffered Rendering

Reopened hoping for OpenGL shader depal can help this issue see #10908 (comment)

[ghost]

Closing the game is work fine so now
