Rejuvenate performance?

[TheGrandPubaa]

Having spent a couple of days messing with homebrew for the new Rejuvenate hack for Unity, I'm curious whether the performance issues with certain emulators are due to very little optimization because of the short time-frame in which homebrew development has been taking place or some kind of artificial speed/memory limitation imposed by Sony on any software that runs within Unity. It's a super exciting time to be a PS Vita owner(at least in the exploit sense), but it is difficult to conceive how far the potential of Rejuvenate can go in terms of speed and usability.

Realistically, what can we expect in the near to mid term regarding Rejuvenate? Are these issues things which can be overcome?

I was wondering this same exact thing. Hopefully someone can shed some light on this matter.

There's no limits in terms of PSM/Unity (those are imposed by PSM/Unity sandbox, which we are not in). However, it is a mystery how fast the Vita actually runs. I've been asking people to do tests, but there hasn't been any response. From looking at leaked references, I suspect that the Vita's CPU is limited to 333MHz per core, but that seems unreasonably low. Until that mystery is solved (should be easy, just do some timed tests), we don't know how fast it runs.

That does seem wicked low considering(based on what i've read) the processor is a Cortex A9 ARM chipset. Granted, it has a decent quad core GPU, but still. I'm impressed Sony was able to get a fully-functioning PSP emulator running under those constraints.

A simple program wich starts a timer, do a certain amount of asm("nop") then stops the time could give an idea of the cpu frequency, right?
(considering the program runs on only one core)

There is no emulator. There's psp hardware inside.

This might be a question that is not related to the post, but do you know anything about what coldbird and acid_snake are doing? it came across my mind
