Increase scrolling framerate
 

Hello everyone
Is there a way of increasing the N900's scrolling framerate? There was a thread on it already but there it was about Qt and Fremantle not being Qt based. I'm wondering if you can up it to 60 fps another way?
Thanks

I noticed that scrolling gets smoother when I overclock. You could try that.

I'll try that later today

WARNING: Overclocking may make your device becoming a little unstable at some point. ie: some video cannot be played or some pictures cannot be display. Camera app will not run unless you get the right frequency cpu.

Phone become much faster on single task. But when opening app manager and Browser you'll end up with a freeze. Just a browser also could lead to frozen windows. But hey it's happened to me, may not happening to you. OC is only good when playing Psx4all though :( I overclocked mine to 1GHz and it runs smoother. But there is also a downside. Nothing is Pro all the way, there is always CON!

can somebody please fix this?60 fps throughout the phone?pictur scrolling is horrible!!

Re: Increase scrolling framerate
 

app mgr and browser dont freeze at all for me, im overclocked to 850mhz or 1ghz or default, depending on what im doing, never had a freeze issue or any probs with it whatsoever, scrolling and general operation of phone are much better when im oc'd

But im sure there is a file that could be modified to alter the friction of the scrolling...i mean the same way transitions.ini can be changed.

See the scrolling in Mediabox, its awesome, just like the iPhone, which despite how much i hate apple, scrolling and the ui generally is fantastic.

Just to add in im typing this on my OC'd (1.1ghz), dual booting (Android + Maemo) :)

Re: Increase scrolling framerate
 

overclocking will increase scrolling and responsiveness and everything else.

it is at your own risk.

im overclocking for about 4 months and i dont see any bad effects.

using too low voltages will NORMALLY cause abnormalities like a non-functioning camera.

i use ideal settings, and when my activities with the n900 gets tough, i overclock from 850mhz to 1150mhz, ideal settings.

even at stock, the app manager uses 100% CPU because its populating all apps installed and cached repos.....so in theory, the more repos and apps you enabled/installed, the slower the app manager and less responsive the device is.

i use x-term in installing and uninstalling, this helps reduce the burden.

it doesnt increase from overclocking the max frequence..
if u increase the minimum to 500, u'll get perfect scrolling along with elasticness etc

Re: Increase scrolling framerate
 

The problem with scrolling on this device is that the display driver does not support VSYNC. It never will. You can thank Nokia. You will get screen tearing either way.

Re: Increase scrolling framerate
 

according to what i heard, the vga is dx10.1 supported
so vsync is hardware limited or software?

Re: Increase scrolling framerate
 

SW limited at the driver level. HW supports vsync.
btw, DX10.1 is a Microsoft Windows term....

Re: Increase scrolling framerate
 

i read the hardware specs on wikipedia
and i think directx is like a graphic encoding system..
anyways doesnt matter, it jus shows that vga is not a dumbass one
i remember my old 32 meg nvidia supporting vsync

does nokia have a good reason or justification to half the missing features in n900?
like voice?
dont say that maps1.0 is qt based and still being developed.. coz qt is graphic.. voice nav is.. sound? and the current maps app already shows where to turn
is it too hard to put up voice too?

Re: Increase scrolling framerate
 

Direct X 10.1 is a Microsoft API, and 10.1 compliant cards meet the hardware spec to get 10.1 certification. N900 gpu is OpenGL ES 2.0 based.

I think the VSync issue isn't a SGX530 issue, but has more to do with Nokia's implementation.

Re: Increase scrolling framerate
 

and again
i'm not a programmer or a computer tech
i jus assumed, like u said, dx10.1 is reference to hardware specs which is good, so why cant it have vsync?
complain to nokia?
isnt n900 supposed to be a high end device
-__-

Re: Increase scrolling framerate
 

this is the only complaint i have left for the phone..isnt there ANY WAY we can get smooth flowing scrolling like on the iphone?(sorry for the comparison!)
imean i fixed the transitions with transitions.ini...fixed the laggy feel of the phone with overclocking. if people pay enough attention to this thread like the overclocking thread, im pritty sure some genious programmer would swoop in and save the day!(again..)
please!some one out there to STOP the tearing and low fps??
ive seen the web browser scrolling on youtube for froyo on the n900 and it SIMPLY DOES NOT TEAR!!even for opera btw.
i would LOVE TO SEE THIS FIXED!!

wait for meego i suppose

Re: Increase scrolling framerate
 

When I used HTC Kaiser the XDA community made better drivers than originals for it. Why not do the same here ?

Re: Increase scrolling framerate
 

does any one have an idea on how to add vsync to the phone them selves?
cuz thats what makes it really smooth.
