    <p>I have a java application I wrote that loads up a TTF font and uses the drawString method from Graphics2D. This gets called every 50ms with the x and y positions changing each time to make the text move. When I run the program on Windows, I get 0-1% CPU usage, but on Mac I get about 75% usage. This Windows machine does have a better CPU but there's no way there should be that big of a difference. I think it has to do with Hardware Acceleration and I want to know how enable it. I found some <a href="http://developer.apple.com/mac/library/documentation/Java/Reference/Java_PropertiesRef/Articles/JavaSystemProperties.html" rel="nofollow noreferrer">Mac specific Java properties</a>, but none of them lowered my CPU usage. Any ideas how to increase Java 2D performance on OS X? Thanks.</p> <p>EDIT1: I thought that these properties would help but they didn't.</p> <p><code>System.setProperty("sun.java2d.opengl", "true");</code> <code>System.setProperty("apple.awt.graphics.UseQuartz","true");</code> <code>System.setProperty("apple.awt.graphics.EnableQ2DX","true");</code></p> <p>EDIT2: <s>You can download the project source and byte code here: <a href="http://drop.io/ExampleScreenSaver" rel="nofollow noreferrer">http://drop.io/ExampleScreenSaver</a></s></p> <p>EDIT3: Since drop.io no longer exists, I uploaded the project to <a href="http://code.google.com/p/example-screen-saver-java/source/checkout" rel="nofollow noreferrer">Google Code</a>. Now you can browse the code without downloading it. I still have no idea how to approach this problem so any help would be appreciated.</p>

    2. CONo, but I'm fairly certain it's not the computer. Both machines have Core 2 Duos: Windows is 3.0GHz, Mac is 2.0GHz. Windows has 2GB of RAM, Mac has 4GB. Windows is using integrated Intel graphics, Mac is using Nvidia 9400m. Windows runs it as expected, Mac hits 75% every time. Increasing the refresh time from 50ms to 500ms obviously doesn't look smooth anymore and the Mac is still at about 50% CPU usage.

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
