Sean,

I wouldn't say AR is non-functional.  When I enable it I do see a difference.  
Although, in almost all cases it makes it worse.  I see jerky scrolling and 
screen artifacts.
I am using 9.5.0 Business.   I compiled the app in 9.0.4 Indy, and m=562.   
Interesting that I just tried it on a Moto G6 and m=585.  Slower than the G5!

>> Is this timing consistent if triggered by a button?
That's how I am firing this.

>> What timing do you get with lock screen muted?
If I comment out the lock screens, I get m=756 (Moto G5)

    Hi Dan
    
    I don’t think this is fully related to your issue based on the script you 
show but...
    
    I’ve been doing extensive testing this week and have come close to the 
conclusion now that AcceleratedRendering is completely non functional for all 
platforms. However, I’ve got a feeling that none of my recent emails to LC on 
the matter have got through during their outage. 
    
    Is no one else seeing this loss in performance? So far all my tests have 
shown it to be affecting every platform standalone and the IDE. 
    
    Back to your issue, Dan. 
    What version LC are you using?
    Is this timing consistent if triggered by a button?
    What timing do you get with lock screen muted?
    
    Also, put the timer calculation to a variable to ensure it is not the 
answer dialogue itself producing erroneous timings. 
    
    NB. Additionally, if your groups are not moving up down left right then 
they are best set to static rather than dynamic or scrolling. This won’t be 
affecting your performance in this instance but worth noting. It’s only useful 
setting it to ‘dynamic’ if the values, text or images are changing 
frequently/rapidly or moving about the display.
