Hi 
I've created an UTFT Library benchmark, test it, and tell me your results !!!
I have 1344 points on my due.
Hope you'll like the demo

It is a little unfair to expect Benchmarks for such a big display.
Anyway, I ran your sketch on a 800x480 with a CTE DUE shield : 960
I then ran it with UTFTGLUE class on top of MCUFRIEND_kbv library : 537
It would be far more interesting to compare the ILI9481 type of 480x320 controllers.
- there are many more 480x320 owners
- there are optimised libraries. e.g. <TFT_HX8357.h> and <TFT_HX8357_due.h>
- there are a lot more Mega owners than Due owners.
David.
p.s. I removed the UTouch calls. They do not do anything useful.
the MCUFRIEND_kbv library does not support angled text
Have the same LCD
Read the sketch, its scales the points according to the number of pixels
Well, you've got better results than me, because the lower the better
David wins with his glue library!!
I hand (butchered) optimised UTFT to 16 bit only, and I got 614... Kudos David

Actualy, theres a bug in my code, I will upload the good version tomorow (The points are not change correctly with the resolution, it was a silly error from me xD)
Now that I overclocked my due (114MHz), i'm getting 1305 points (with the bug still in)
I found the over-clocking ideas that are out there for the DUE, actually reduce performance of UTFT....
I moved away from those long ago...
But, will be interested to see your new version!
Regards,
Graham
PS 800x480 CTE50
Here is the new version (hasn't been tested)
I cant test it now, but if you can, tell me your score !
Now, the higher, the better (This is the correction I was talking about)
ArduMark.ino (6.28 KB)
Hand butchered UTFT score = 576
Standard UTFT score = 960
Not sure higher is better!!!!!!!!

Graham
WHOO HOO!!! my 1500th post!!! 
Yes, sorry ^^
But normaly, il you test on a lcd with a different size, it should be the same score (If you dont change of library)
Sorry for bad english

TFT_HX8357_Due does not support angled text but here are the results for a 480 x 320 screen.
ArduMark test with HX8357_Due library
TFT width = 480
TFT height = 320
TestA time = 1697
TestB time = 219
TestC time = 1453
TestD time = 20
TestE time = 698
TestF time = 80
Points = 61
Results on a Mega:
ArduMark test with HX8357 library
TFT width = 480
TFT height = 320
TestA time = 4648
TestB time = 219
TestC time = 1347
TestD time = 66
TestE time = 593
TestF time = 114
Points = 92
I suspect the points calculation does not correctly compensate for the resolution so I have printed the execution times in milliseconds. Only TestA seems to have a fixed size and thus would give a result that is equivalent to a larger display. On the Mega millisecond timing variables were set to "unsigned long" to avoid overflow.
Results with Due running the basic UTFT library are:
ArduMark test with UTFT library
TFT width = 480
TFT height = 320
TestA time = 5462
TestB time = 650
TestC time = 8900
TestD time = 78
TestE time = 2027
TestF time = 2860
Points = 291
Results on a Mega with UTFT:
ArduMark test with UTFT library
TFT width = 480
TFT height = 320
TestA time = 24429
TestB time = 1727
TestC time = 23079
TestD time = 422
TestE time = 5235
TestF time = 9492
Points = 983
In these UFTF cases TestF is drawing rotated text so would be expected to take longer.
