Hi all..I have an xperia Arc S..still on stock GB no changes at all..I tried to play some of my videos I took with LG 3d and S2..they were 1080p..so as I expected they were slow and and the device couldn't render them well..so my question is that did u guys noticed any improvement in Full HD playback when overclocking the CPU to 2Ghz or using any scripts or costume kernels??so I will think about changing to such conditions if there are any improvement..thanks alot for any help..PEACE

Hey Ppl
Now that the Arc can be overclocked, is it possible to make a tweak, to record video in 1080??

no its not possible
because for recording in 1080p it is necessary that arc also play 1080p mp4 file.
i over clock arc to 1900 MG-HZ and play a 1080p mp4 song its played but problem in audio sync.
its not properly played mp4 1080p videos
and over clocking upto 1900 MgHZ also heat up the arc quickly
an other problem is that at this time we did not have a custom camera app for arc that have an option of making 1080p recording
i think if the Developers work on the Camera it will be available.
Cause the Xperia X10 have on Custom Firmware the function that he can record 1080 Videos.
basically i dont think its possible to take 1080p60 or 50 movies without big compression. Reason: you cannot write this amount of data fast enough to SD Card.
Maybe someting high compressed and interlaced might be possible, or only short time which are fitting onto internal memory and is moved after that to external.
But again, reading from SD card must be fast enough for playing them correctly (or fill up mobile memory.
for creating/viewing 1080p60 movies write and read speed has to be above 12MB/s (thats the datastream of the movie). this is also the reason why you cannot watch 1080p60 movies via Wireless G properly.
Sorry guys for wrong Category...
EDIT:
Moved to the right Category now...
Weird the iPhone 4S uses exactly the same camera, as the Arc, and it can record in 1080p....

Single core against dual core. iPhone 4s has more processing power in this case.
Im not really sure if this is the sole limiting factor though.
Hi, first at all i want to say that i tested nearly every rom & kernel combinations and still i'm not satisfied with the performance. Overall device is performing better (i'm running @1,4GHz - Stock Plus & DoomKernels 15-20) and in 3D heavy games framerate is higher for sure, but there's a lot of stuttering and sometimes games are unplayable (for example Backstab and Asphalt 6 with annoying one sec stuttering). On stock kernel game (Backstab) is running without any performance issues (only few dropped frames when there's a high draw distance) and the device itself is running "only" at 1GHz. Now something about DoomKernel - interface is not running smoothly (with simple 3D live wallpaper but 2d is ok) and i can give you another gaming example with MC3 - main menu is running at ~20 fps (and game itself is also stuttering) and on stock kernel/stock plus it's much smoother. So there is any fix for my problem or it's something wrong with my arc or what . Stock kernel by Sony > custom kernels? Something is wrong here... Thanks in advance and pardon about my english .
try playing on performance governor
I played with governors with no result ;(

okay, now i'm gonna "stress test" every single governor available in kernel ; d
Bump!
I've added a video :<

Have you tried Stockplus Kernel? It's based on DoomKernel but has a lot of changes and tweaks. Some people report better results with it when compared to DoomKernel.

I can't help with a solution at the moment and I must admit I was skeptical about your statement, but after checking, it does appear(from my observations) there is a noticeable lag in video playback on my Sony XPERIA LT26i JB 6.2.B.0.200 release with DoomKernel v1
I have a mkv(H.264,AC3) 720p video I know very well and use as a video benchmark and it should be smooth with no lag as it was on ICS on an XPERIA S.
The video has some structural components of a spaceship which is panned from end to end over an extended period and it's easy to spots frame lag/drops.
I have viewed the video in both MX Player Pro and BSPlayer, with Hardware encoding enabled and there does appear to be a visual lag.
I enabled settings->Developer Options->force GPU rendering in settings and this made no difference.
Using my old XPERIA X10i I played the same 720p mkv using BSPlayer and it was very smooth with no noticeable lag.
Something is a bit odd when an Adreno 200 plays videos better than an Adreno 220.
i have some question about kernel.
kernel usually have 420p and 720p version, nah my question is what the different between their ?
tell me the effect when i used 420p kernel and 720p too :good:
Oh, i used my phone for gaming and social media priority
my device :
Device : Xperia Play R800i
ROM : XPLAY HONAMIv2
Kernel : LuPuSv7 [STOCK ICS/GB 720p
The 720kernels: you can watch and record 720p video and it uses up a little more RAM
Hello there,I have a question that I want to ask...I know a lot of Xperia S/SL user suffers from lag in MX Player while touching the screen...And the problem also happen while watching videos from the YouTube apps...
I have the solution,that is by changing "debug.composition.type" from "dyn" to "gpu" from the build.prop...It is the equivalent as disable HW overlays in dev option...And it is the same as disable Project Butter and let the GPU do all the work for screen compositing...
I already test it and it work...MX Player and YouTube apps run smoothly without a single lag while touching the screen...
My question is,it is ok to change "debug.composition.type" from "dyn" to "gpu" and let the GPU do all the work for screen compositing???It is going to effect the system,hardware or the battery life???
Changing it from dyn to gpu should save battery
Also xperia gpu is crappy meaning that either way your allways going to have some lag
Here is some extra info
Dyn = cpu and gpu
Gpu= gpu only
Cpu= cpu only
Mdp= multi depth something (buggy on xs)
C2d=core to duo (kinda like dyn only more gpu use)
There are some others

Thx a lot for your reply...I change it to "gpu" and notice a bit of lag while scrolling through the setting...
I've been wondering did other Sony device suffers the same problem as Xperia S/SL...Or it's just Sony fault because doesn't fix this problem...

I think its older sony phones , i get lag even scroling through photos (got a S)
Z1,ZU,XC,Z dont have any noticable lag when it comes to small things like youtube
