Yes, depending on the amount of data to be sent (i.e. size of the update region), and the required update rate. But this is the fundamental limitation I was talking about above.

Of course, though I'm not sure whether the desktop and apps can/could be scaled arbitrarily while running without all sorts of graphical glitches (thinking about an accelerated desktop). Certainly for individual apps (such as your cool liqbase) this is true.

No comments about powervr, but 4.2008.36-5 diablo software update had introduced fixes for tearing problems in the omapfb kernel driver.

You can even have full 800x480 resolution tearfree rgb, but CPU has to run at 400MHz for that (RFBI speed also depends on CPU speed via some multipliers). When running at 330MHz, screen updates are not fast enough for full resolution rgb updates, but lower resolution screen updates should be ok.

Serge,
thats excellent, I'm just at a critical point and bringing myself back into RGB alignment could be beneficial.

I'll have a play.
