You keep forgetting one HUGE detail...
XUI2D is still beta... once officially released, I am sure the performance will be even higher...
As I said, I am not a games dev, but the way you are criticising is not a very constructive one... you are just throwing specs and result without any further conclusion not suggestions, and at times, not even additional info.
If I was
@Erel, with all the criticism this is having, I would have just abandoned...
Try to see the larger picture... when B4ppc first came out, it didn't even produce a proper .exe! And look how far we are now!
Be constructive in your critics.. don't just say "on my 10years old phone it doesn't work as it's supposed to".
Give additional info, like what apps you have running in background, Android version, etc...
Remember that
@Erel's examples are just that... examples, proof of concept... NOT A FINAL PRODUCT...
I am sure
@Erel is very much aware of the engine weaknesses, and working hard to gives us a product HE would be proud of... he doesn't settle for less than that.
