if your like me and don't care about fancy transitions. search transition in the HAM and get the transition control and set all values to 0. its not a real speed up, just a visual one

Man, hw acceleration works great! Hopefully it stays stable. But the extra smoothness is nice on the eyes for sure.

HWSync hasn't anything to do with hw acceleration, because it's just enabling the vertical-blanc-interrupt-sync. First off this cause the animation to look nice and 2nd it makes the device lags because the software gets sync to the vertical-blanc interrupt of the graphic-processor. This can only work if the software making the transition can draw a full transition in one (1) vertical-blanc (vbl). Obviously this isn't your observeration (lag) and although on many device its cause a reboot loop.

FYI, my N900 gives:

Code:

real    0m 20.64s

user    0m 19.05s

sys     0m 0.05s

Sorry for the noob question, what is this bc? couldn't find it on app manager :S

bc is command line calc program - one of those handy old linux utils. http://en.wikipedia.org/wiki/Bc_programming_language

to install try

Code:

root

apt-get install bc

Not too sure which repos it's in...

bc = big calculation or big num(ber). It's a number larger than double integer or any other number bigger than a 32 bit processor and thus doesn't fit into a cpu register.

well for me i have smart reflex enabled
heavy usage (browsing - mediaplayer - webos games) about 8 continuos hours
and if standby only gsm - a bit mediaplayer well last about 3 -4 days

Code:

real     0m 15.44s

user     0m 14.09s

sys      0m 0.04s

tbh with all the settings enabled from this guide, all of which i already had anyway d=, if you just lower the cpu to say 250 with smartflex, lower your screen brightness you really are going to see an improvement in battery power

and if you are going to go power mad with 1050mhz ect then you will see an improvement compared to stock 600mhz
