Shader Options

Here some details on the new added options to PPSSPP:

950/XL, Elite X3

You mostly don't need to change those, keep as default.

All other devices

• 1 (Cache):

This option will cache the graphical shader to disk for faster load next time.

• 2 (Precision):

This option will force lower precision for less power consuming and a bit faster,

if you felt game is slower than usual, try to turn it off,

if is not effective then keep it on back.. it better to keep this options on

• 3 (Depal):

This not compatible with all games but it's faster on many other games,

it's off by default, turn it on based on your tests.

• 4 (Float):

This should be always on, for older phones

• 5 (Lights): This will turn the lights shader off, so you will notice that in the game,

added for testing in case it can make things faster.

• 6 (Fog):

This also should be always off on older phones.

• 7 & 8 (Uber):

Those require newer GPU, if you enabled 3 (Depal) those will go off by default,

so keep them off for older phones.

Conclusion

So the only effective options you may try:

• 3 (Depal)
• 5 (Lights)
• 2 (Precision): as mentioned better to keep it on unless you sure it's slower.

for better testing always Create game config from the pause menu

to avoid making changes over the all games.
