Henrik, what speed are you experiencing - stodag - 01-14-2013 01:25 AM

Henrick i read somewhere jit is workin on your phone, i just wondered what speed your getting if any. thx
Also keep upthe great work.

well the recent video that someone posted in the other thread proof that there is already a good speed boost.

I hope there is a way to get more if the jit is already complete :/


RE: Henrik, what speed sare you experiencing. - stodag - 01-14-2013 08:49 AM

I think we will need things like stronger cpu etc dual thread, to see improvement thats really noticable, i never really thought it would be full speed on a sungle core but hey what do i know still hopeSmile


RE: Henrik, what speed sare you experiencing. - Henrik - 01-14-2013 10:01 AM

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.

ok cheers, Thats good to hear my phone has a chanceSmile

Yeah most emus especially 3d, fpse for example took about a year and half two years to be full speed, good compatibility etc so, im not expecting to much to early.

Nice.... thanks.

Btw. Henrik, can you make a working build from the armjit branch for the mali 400...i wanna test it and let's see what kind of boost it can give to fairly modern android gpu's.

Well if you have time of course. (I know that you don't have much and will be happy if you just reply "no")

Hm, i don't think jit's crash is releated to gpu.i guess,right now it only works on arm cortex-a8 solutions


RE: Henrik, what speed sare you experiencing. - stodag - 01-14-2013 01:23 PM

yeah its an a problem with an instruction in our cpu, not the gpu.

Thatd what i was told Smile

I think Henrick uses A8 cpu, so maybe only works on them at the moment Sad

He will get there thoughSmile

And why it works on a galaxy nexus? It has Cortex A9 but the same GPU then I think that this is not caused by the processor both use Armv7rev2 instructions.

Well it doesn't matter, anyway arm jit still have to improve a lot.
Let time to the time and they will do it.I only can say thanks to the developpers and support them buying the apk or reporting bug or those things.

Well actually Fpse took much more time! Schtruck made his first port of Fpse (PC version from LDchen I mean) more than ten years ago on Windows CE devices. Then he made the Windows Mobile version. Finally he made the Android version after ten years of coding Fpse for other platforms, so with experience from the other "mobile" version.

So I'm amazed to see what PPSSPP can already achieve, that's huge!

Henrik .. may i ask you , What is your main Focus on PPSSPP Project ?

Is it Mobiles / Tablets or PC !

Personally i would love to see all the improvements on The PC version more than anything .


RE: Henrik, what speed sare you experiencing. - cloud1250000 - 02-10-2013 06:29 PM

well, the pc version is working pretty well and I think the only thing left to do (because we already have good speed ahah) is increasing the compatibility which will affect all the platform ahah....

So I don't understand the meaning of focusing on pc version -,-'


RE: Henrik, what speed sare you experiencing. - Henrik - 02-10-2013 08:11 PM

I switch my focus back and forth, I think all platforms are important. No need to worry.


RE: Henrik, what speed sare you experiencing. - Shinox - 02-11-2013 02:58 PM

No matter what the result is .. keep up the good work Henrik Smile
