Henrik, what speed are you experiencing

[Henrik]

There is lots left to do to improve speed. Not only can the JIT be even faster, but GPU drivers on mobile are generally very bad at dynamic geometry (which PPSSPP uses extensively) so I will have to compensate for that by caching vertex data, etc.

I expect that on reasonably modern phones (maybe a bit newer than my Nexus S) many 3D games but not all will be playable at full speed when fully optimized. But we will see. I will do my best to get good speed on slow phones too, but it will take time.
