I enabled the "Show touches" option from developer options, and woww.. It is tracking my finger really fast.

Now, why there is a touchscreen problem on Galaxy S3 with ICS, while not on other devices like Nexus S or Galaxy Nexus.

@Devs: please investigate this issue. Galaxy S3's touchscreen is capable of this, and it is a software related issue.

Have you asked the dev what he had changed in his Rom? Maybe he is aware of it and can provide a solution. I am also interested in this. Thanks for bringing up this issue.

Thankfully there's a possible fix for this. Probably the only thing that bugs me about the S3. My old S2 on GB felt much better when scrolling. Didn't update it to ICS because it didn't feel as good.

I changed the cpu governor to hotplug, touchscreen feels a lot better now.
I also changed the CFS Tweaks to "Thunderbolt script default" from STweaks, but I don't know if that affects.

how did you change the cpu governor to hotplug?

Firstly you must flash a kernel that supports hotplug governor, I used SiyahKernel.
Then you can use STweaks application to change.

Watch this video and you will understand what I mean: http://phys.org/news/2012-03-microso...een-video.html

Edit:
I just installed this multitouch test app to my both phones, and moved my finger on both at the same time, Nexus S' tracking is faster..

what is the latency of the GS3 screen? is it totally hardware governed or can it be changed with software?

Firstly I thought it is all about hardware limitations, but after flashing a JB rom then I realized that our hardware is capable of.

So no official figures on either ICS or JB? Obviously no official figures for JB as no official firmware yet

Are you not all simply noticing the difference (and improvements) resulting from "Project Butter" in Jelly Bean? It was designed to improve speed and responsiveness - the exact thing I think most of you are complaining about in ICS (compared to JB). So yes, I'd fully expect JB to feel more responsive on identical hardware...

No because there isn't any issue on other devices, like Nexus S with ICS.
I think the problem is in the Samsung's kernel for S3.
