earh defense force portable 2 laggy on android

[tiamat999]

on windows pc the game runs fine on android tablet it is really laggy is it that tablets are not powerful enough to play it or something else

[daniel229]

That game is also slow on PC,42fps max in this scene.

[tiamat999]

Thats normal on the pc when playing it the lag on android is the real problem

[tiamat999]

would be nice to get some input from anyone

I would not get my hopes up, the Sandlot games have a legendary tradition of being either badly optimised, or simply going far beyond every platform's capabilities. I also have EDF 2 on ps2 and EDF 2025 on ps3. Guess what, they are all lagfests on both systems.
So it's really no wonder that they run slow in an emulator on a mobile phone ;).
The best way to play is in the non-buffered mode. My Exynos S3 gets around 13-15 fps in-game, and more in underground levels. Too bad that the sky is missing in unbuffered... Would be great if we could get it back, black background in day scenes is not nice.
So if a 3 year old phone can get almost 50% fps, I'm quite sure that something like a Nvidia Shield tablet could play this at 100% speed in non-buffered. Anyone care to check that?

@daniel229 is that how it's supposed to look? The shadows look wrong. Seems like it's probably doing blending against its render target there.

[daniel229]

Yes,they are wrong.

"20900 flushes" is why it's slow, neither OpenGL nor DirectX drivers are efficient enough to let you do that. Somehow we fail to combine the draw calls it makes, it would be interesting to look at a frame display list dump.

[daniel229]

frame dump here.

Thanks, this is another game (some Gundam game does it too) that ruins performance by switching culling back and forth, they must have a weird mesh-to-tri-strip converter.. I guess I will have to implement a workaround for these games.

[Elwood89]

That's great news, so there is hope for us!
BTW these are not shadows, I think that that is the developer's idea of bloom... nice, black bloom...

[tiamat999]

so any news?

[tiamat999]

When can we expect the work around just wondering

[tiamat999]

1.0 did nothing for it sadly come on I really want to play this on my tablet badly

[Elwood89]

I would not hold my breath... this is a niche game, and the devs probably have many more pressing problems to solve before they even get to work on this. So we can only hope that some day this might get fixed.

Vertex Cache slow down the game 30%+

Vertex Cache on

Vertex Cache off

[unknownbrackets]

Yeah, as I recall the issue here is that it brings almost no benefit - so it just hashes more, but never ends up caching or winning any speed.

[unknownbrackets]

With #10973, we should now be using larger vertex buffers and caching a lot better. Also, vertex cache is off by default now.

As such, I'm going to close this - feel free to comment if performance hasn't improved in the latest git, and we'll reopen. If you're reading this and the year isn't 2018, you're probably seeing a new issue so it'd be better to open a new issue than comment.
