Since last update many things have been newly integrated into AT engine, some of them are rather cpu heavy.
You may check in time, if your Android device will be sufficient.
For this we have developed a simple HTML test routine for it:
Please press the following 8 show buttons directly one after the other and as fast as possible. Due to the structure-related latency in the construction of the HTML page, the performance of your Android device can then be estimated.
First click:
-- ok --
Second click:
-- ok --
Third click:
-- ok --
Fourth click:
-- medium --
Fifth click:
-- ok --
Sixth click:
-- ok --
Seventh click:
-- ok --
Last click:
-- ok --
Result:
>> Your Android device is well equipped for the update. Only weapons like Quick Strike Dagger may not work reliably anymore.
Thanks for using our first augmented PR Iso-latency check.
