Re: Graphics Performance issues?

SprintTouch08 have you read my previous post?

No.. the problem is not exaggerated. I really don't want to think how a full wide resolution video will run on HTC Touch HD, the media-centric device from HTC (uses the same chipset)

The LARGEST flaw in the xda/wmpoweruser video test is theyre comparing a video played on DIRECTDRAW getting 170% to a RAWFRAMEBUFFER at 400% on the Omnia. does anyone else see the inherent flaw in that logic? (rawframebuffer is NOT using the 3d drivers, that's why).
As the author stated there, it shows the maximum performance archived by the device. He tried ALL AVAILABLE video output types and noted the best for EACH device. What's wrong with that?

Side-by-side Ominia - Qualcomm devices , DirectDraw performance is way better on Omnia.

Is the DirectDraw on Touch Pro hardware accelerated? I don't think so.. The main problem of Touch Pro is 2D performance.

Omnia's CPU (Marvell PXA312) has integrated hardware video acceleration.

here’s a Phone Arena SPB Benchmark between Omnia, Xperia X1, and Touch Pro: http://www.phonearena.com/htmls/Sony..._2072-p_6.html .

It is VERY CLEAR that the Qualcomm cpu is 5x SLOWER than a Marvell for even 2D on the SAME OS!! Note that this benchmark is still useless for measuring 3D performance, but it’s a sign and the writing is clear on the wall.
