How i can disable Hardware acceleration? Delete the file "local.prop"?
no dont delete lol
just debug.sf.hw=0 i think ...
Thx i will try it ...
what are the benefits of disabling hardware acceleration?
Apparently, disabling HWA improves battery life. I haven't actually tried disabling it though. My battery lasts a couple of days with HWA enabled, so I just keep it on.
from what i have experienced, enabling HW accel slows down linpack, therefore giving lower scores (9 with JIT only, 8 with JIT and HW accel)
should I still enable it anyways?

linpack score will be low but snappier and faster while using phone

Hi there!
Why does LG disable these features in the P500? Wouldn't it make more sense to squeeze as much performance as possible out of a device? Average users will buy this phone, install Angry Birds, and be shocked at how awful it performs. I haven't tried it yet, but I guess with those tweaks enabled, the more demanding apps run a lot better.
Do other manufacturers disable JIT and HW accelaration as well, and if yes, why?
I searched all over the forums and couldn't find a satisfactory answer.
Thanks!
im looking for a reply on that, too...
Hmmm...I didn't know that these were disabled.
Actually... Angry birds does NOT run better with jit and HW acceleration enabled.
MAYBE they will eat up more battery when enabled?
hi im using Megatron v1 on my O1. and then i run quadrant advanced it shows me that my bechmark is ~540 sometimes even lower. whats wrong? i think it must be about 1000..
550 is a very good score for our device. over 1000~ is a bug of the benchmark software, this has been discussed in this forum already.
Over 1000 is a buggy you say I was wondering how mine got over 1300 score haha
so you say my quadrant advanced is buggy?
Maybe your stagefright was disabled? But don enable it! Stagefright gives me lots of problems.
man wtf is that stagefright?:?
I believe you can write "stagefright player" into google just like everyone else
Long story short, its a video/audio playback engine, but its little buggy in our android version - some video formats cant be played, and since theres H264 decoding test in Quadrant which fails to proceed, it gives way too good score.
Ok, noob question here. But can someone please explain to me what 2d hardware acceleration is/ why you'd have it enabled/disabled? I'm reading threads about people arguing for/against it, but I'm not really clear on the subject.
Thanks!

WHAT IS 2D ACCELERATION?
2D hardware acceleration basically offloads all the drawing of the UI from the CPU to the GPU, this results in smoother scrolling and less power usage (because the GPU is much more efficient at handling graphical processes).
AN EXAMPLE:
People often complain of android being slow and "stuttery" when scrolling through menu's and when they move to an iphone they just love how smooth everything moves. A lot of this can be attributed to GPU acceleration (it's not the entire reason) but it is a large part. So with GPU acceleration enabled, android devices become buttery smooth. ICS is the first version of android to force GPU acceleration and that's why there was so much fanfair over it's release.
THE DOWN SIDE:
So far in my experience the down side is to do with un supported apps. There is 1 app I have that does not like 2d acceleration (kingston office). It gets transformed from being stuttery to buttery smooth but the text dissapears when you start scrolling.
CONCLUTION:
Enable it
have a look at http://forum.xda-developers.com/showthread.php?t=1887997
there is an easy mod for devices with adreno 200 gpu. Worked very well for me on DSC. Didn't made a benchmark, though it's just subjective impression that the rendering is faster.

hmm...such a super easy mod... tried it on longhorn 2.9.3-b1 ... can boot normally.. tho quadrant advanced shows the same as before ... 19xx

... thats what they said in the thread, in benchmarks it doesn't show. I think it does show in day to day use, and I think its o.k. to use the gpu for rendering und free the cpu for other tasks.
But I also found a drawback when playing mp4 with the gallery. There are hickups in fast screen changes, when there are none with cpu rendering. There is definitely a reason, why the gpu-rendering is turned off.
I circumvent that with bsplayer where you can select hardware vs. software rendering in the preferences.
I get the same effect with debug.egl.hw=1 in /system/build.prop
So no need to remove files or edit in /system/lib/egl/egl.cfg
Can't say too much about performance, but battery life seems to have improved! CM7.2 here with n0p's latest kernel. Need to try this on ICS and see if it has similar results!
As far as I know you save battery because the CPU is freed up from the loads of rendering it handled before, before the GPU would only be used when it was needed. You get an all around boost in performance with the UI more than anything because now the GPU renders graphics entirely and not just in 2D/3D operations. Some people say benchmark scores are lower because of this, I say it has to be somewhat inaccurate but my guess is that since it's now being used for 2D/3D along with everything else it might possibly effect the performance the GPU had when it was fully freed up. But when you really take a close look, if you've really tried it for a long enough amount of time, you'll see that the drop it's barely or even not noticeable at all. I think you guys are all happier with a faster UI, I know I am.
Makes more sense now, right?

Do NOT try on ICS unless you have ICS specific Adreno 200 drivers. Adreno 200 is different on GB and ICS/JB, usually the JB Adreno 200 libs will work on an ICS ROM.
Hello everybody ! Basiclly i want to ask if it would be a good idea to try disabling CPU rendering for a GB rom? Im currently on CM10 but really cant use it too much cause some games like Fruit ninja force close and cant even listen to music whatsoever. But the main thing that i dont like about GB roms is that they are very slow compared to CM9 or CM10. Would disabling CPU rendering make a difference? People say it makes a big difference .
It's probably possible, but I don't have the slightest idea on howto do it.

No 2D GPU rendering is available on GB. All GUI is rendered by CPU. So turning that off would leave you a black screen (except in games).

HW acceleration was introduced in Honeycomb. Only the CPU is used for 2D rendering on earlier versions
