Current state of Snapdragon-based CPUs in PPSSPP

But if you're talking about frameskip, you probably just have your settings wrong. Frameskip works perfectly fine on my device. For example, Dissidia runs great at 1x, but at 3x render it is going at 27%. Enabling auto frameskip with frameskip set to 1 allows it to go at 50%, and setting it to 4 allows it to go at 100% speed.

Of course, I personally prefer the lower render resolution to frameskip.

I've seen multiple hacks go in recently, so I don't know if compatibility has gotten worse. Probably you are right. Hacks are horrible for compatibility. I do know that several fixes, improving compatibility, have also gone in.

What games crash for you? Are you sure these are somehow snapdragon specific issues? Maybe the games just crash? Maybe it's because fastmem (which makes things faster, but can crash more often if there's a bug) was changed to on by default.

I'm not sure there's any regressions or things specific to Snapdragon getting worse.

Can you be more specific?

It's not that I'm using the auto frameskipping wrong, but the auto frameskip IS worse. For example, I tried Fate/Extra with 9.6 and 9.8 to test this. Like you said, using frameskip at 4 with auto lets the game run in fullspeed (1-2 is barely an increase and has noticeable slowdown), but the game is incredibly choppy. On 9.6, auto frameskip is just as fast when it's set to 4 on 9.8, but the game is very smooth and consistent for the most part. I made sure to check the rendering resolution for both the same and with the same options ticked before testing. I've also tried Super Robot Wars Z with both versions. Super Robot Wars Z barely lagged with 9.6 auto frameskip, but with 9.8 the game starts lagging as soon as a lot of particle effects (like explosions and big attacks) appear. Yes, frame skipping gets rid of it, but the animations look very choppy.

But the thing is, most games (well 3D ones at least from what I've played, I haven't noticed much with 2D games) are slower. If there is an increase in speed with auto frameskipping, it works but it's almost unplayable when characters move so sluggishly.

For compatibility (probably has nothing to do with snapdragon specifics though), I've seen some games get better (games that have been working already have fixed graphics), but some games that used to work don't work anymore. For example, CONCEPTION: Ore no Kodomo wo Undukure! says it's working in the compatibility, but it doesn't work anymore. It hangs at a black screen. Same with DOA Paradise. These games used to work, but suddenly they crash or hang instead. On the other hand, games that didn't work before, still aren't playable and just hangs to a black screen.

I don't mean to sound like an asshole, in fact, I've appreciate everything this team has done for this incredible emulator, but it just disappoints me when development for this emulator was going so well (up to 9.6.63-g9c545ee), but now it's getting worse for every release. I also have another device with a tegra, so seeing the two play the same game side by side is like watching day and night.
