in newer git-versions there must be some calculation problems on android.

v1.8.1014 works well for me. but with v1.8.1030 i noticed some problems. first in f1 2009. there the cars are flying around. today i noticed that there are problems in f1 2006 too. the ai-drivers often leave (miss) the track. and if you collide with walls you stuck there and can not return to the track. and there are other games with problems in collision query with the last versions.

please fix that

(with v0.8.1067 it´s still the same)

Most probably related to the known ARMJIT issues currently present in all the latest PPSSPP Android builds right now.

Use v0.8.1-1029-g51596b6 until it is fixed.

See the following issue report for further details. This issue affects a lot of games in very different ways.

Sorry for the mess, optimizing the ARM JIT is hard but it's really worth it, I think I've achieved at least 20% speedup in FF:CC in the last round of optimization and there's more to come. Just need to fix those new bugs too.

yeah,there speed improvement in the latest build(even though it's small detail,but I can see there's speed+ in latest build),but had some minor bug,it's hard to make it good without suffering some bug,anyways the speed up was good henrik,we just need to clean the bug Smile

Omg thank you, there was a long time since i hadn't tested any new build, and with the latest android build i couldn't believe that DBZ Shin Budokai 2 ran at 100% with frameskip in 1, and 80 - 85% without frameskip, thank you Big Grin

i thought ppsspp couldn't work better

There's obviously a limit but I think we're not even close yet Smile

It gets harder and harder to get that last speed out though.

The problem in the game wipeout pure n the latest builds with JIT enabled on Androyd. At the start of the race race cars spark and explode during the race and everything happens in a looped mode. If you disable Jit, then everything is fine with the gameplay, but the speed accordingly very very slow. Sorry for my English. phone Galaxy Note 2 (android 4.1.2)
