Ppsspp: Digimon Adventures graphics Issue when block transfer effects is not enable after #11531

[Gamemulatorer]

What happens?

Graphics issue started in v1.7.1-141-gdf5fbaef7 after implementing the Virtual Readbacks #11531

[hrydgard]

When does this happen?

[Gamemulatorer]

@hrydgard in the latest gitbuild v1.7.1-141

[Gamemulatorer]

[Non-Buffered]

The game also is running very slowly compare to the gitbuild v1.7.1-125

[Gamemulatorer]

Phone Specs:
Mali-450 GPU
OpenGL 2.0

[hrydgard]

Well, this is the opposite of what I expected. Will look into it.

[Gamemulatorer]

Enable "Simulate block transfer effects" in rendering mode fixes the issue but the game is very very slow :(

[hrydgard]

Bizarre, it should at the very least be faster than before.

[Gamemulatorer]

gitbuild v1.7.1-143 fixed the graphics regression but the game is still lag

[Gamemulatorer]

Oops... After a couple of minutes playing issue still happen :/

[unknownbrackets]

Just to confirm - does this happen in v1.7.1-137-g256d5e0b0? Or not until v1.7.1-141-gdf5fbaef7?

And not in v1.7.1-131-gb88b07ea0?

@unknownbrackets didn't happen in v1.7.1-131-gb88b07ea0 or v1.7.1-137-g256d5e0b0 it's only started in v1.7.1-141-gdf5fbaef7

Still happening in the latest builds?

[Gamemulatorer]

Same status using latest beta build

[hrydgard]

I actually got my hands on this game now. So if you can give me a save or tell me what to do to make it break like this, please do so. Is it easy to get it to happen?

[Gamemulatorer]

here's my savedata

block simulate transfer effects fix the graphics issue but still lag I think virtual readback didn't help to speed up the game? (imo)

[hrydgard]

Thanks.

Ah, so you had "simulate block transfer effects" off when you got the artifacts? You really should have it on for this game (and nearly all other games), that's when the new code will run anyway.

I'm completely baffled as to why you didn't get a huge speedup with it on though. It really should have helped...

[Gamemulatorer]

@hrydgard thanks you sir for your concern for this issue and now I totally understand what cause the graphics issue

But why I didn't get a speed up in this game maybe because my android phone is too weak? but I also try this game in Snapdragon 430 Octacore didn't notice any speed up :(

[hrydgard]

I'll investigate later on my phones and see if I find out something. Because this game should run okay on reasonably-specced phones...

[hrydgard]

On my S3 it runs pretty badly but mostly fine on the S8. Still it's slower than I would have expected it to be... probably worth looking into.

[Gamemulatorer]

Sir @hrydgard any update about this?
This will be added in v1.8.0 milestone?

[hrydgard]

I don't know how much more there is we can do here, but I'll tag it and take another look later.

[Gamemulatorer]

@hrydgard sir can you add this game Digimon Adventure to RequireBlockTransfer compat.ini to avoid graphics issue in ppsspp v1.8.0?

[hrydgard]

Yeah, I will

[hrydgard]

@Emulatorer done.

[Gamemulatorer]

I think I can close this now because this game demand a powerful device to emulate smoothly in ppsspp 🤔

Sad because my phone is low specs only 😣 I didn't enjoy playing this game in a low fps/speed using the latest build I tried everything :/

So it's time to surrender 🏳 CLOSING?
