Well, here goes a few things I noticed off the bat.
I grabbed the GL benchmark app, and here a few indicators that it needs to be re-worked for the Xoom:
The Xoom has 27 native Open GL extensions (
MOTODEV > Products > XOOM? MZ600)
the GL Benchmark app only found 21 (
GLBenchmark Result Details of Motorola Xoom)
So off the bat with the app not using all available OpenGL extensions for honeycomb or for the Nvidia platform I'd say that it's "off."
Secondly, the app even incorrectly reads the screen size at 1280 x 752.
So right now I say these needs to be updated before I got too crazy with the results.
I didn't do a cross reference of the utilized libs over the ones "left on the table" but if I get a few minutes I will.
