2011 Mac Min
2.5 ghz i5 processor
AMD Radeon HD 6630M 256 MB
8 GB Ram
Java version 7 update 51
Figured I would post this to the community before contacting support.
How do I know when my Mac mini is using the Intell HD 3000 built in GPU or the AMD Radeon discrete graphics card?
Specific issue I am trying to address:
Poor graphics performance when running a single Java based app.
The app is a stock trading platform produced by TD Ameritrade.
While the app is running ALL scren animations are adversely affected. (minimize/maximize windows, dock navigation, moving open windows etc...)
As soon as the Java app is closed, all screen annimations return to perfectly smooth.
While the Java app is running, the Activity Monitor shows memory pressure is very low and CPU usage remains near full idle.
With no evidence of the CPU or Memory being overloaded I am left to assume its the graphics hardware that is overloaded.
Final note: tech support at TD Ameritrade claims they are releasing a 64 bit version of the platform that is supposed to correct the issues.
Is there a way to force my Mac Mini to use discrete graphics vs the intel HD 3000 so that I can see if this corrects the issue?
Thus I assume your Mini ony uses the Radeon graphics.
From your describtion it appears the problem is with TD's Java
