Hello,
I'm drawing a GeneralPath in a JPanel.
The lines tracing the GeneralPath looks a bit rough even with anti
aliasing turned on.
Here is my paintComponent() override:
public void paintComponent(Graphics g)
{
Graphics2D g2 = (Graphics2D) g;
I have a web start Swing/Java2D application with 2 JNLPs, both effectively the
same, except that one of them sets
property name=sun.java2d.opengl value=True/
On the test machines that I have available to me (Win XP, Linux, Sun Sparc,
Mac) I have never seen a problem with either of them,
Hi Russell,
This sounds like a known Nvidia driver issue, but we couldn't know for
sure without the exact driver version. I will see if we have a similar
configuration in-house to try this on. Also would be helpful to know if
the problem was visible with the usual demos like SwingSet2, but I
I did manage to get someone else to give things a try at the show today.
Here's what we found:
- Forceware version: 84.69
- Driver date: 5/1/2006
- SwingSet2 demo works no problem.
I used http://java.sun.com/products/javawebstart/apps/swingset2.jnlp - correct?
But I noticed that the
You don't need to use webstart, do you? Can you just have them try
running SwingSet2 from the command line with -Dsun.java2d.opengl=True?
Another thing to try if running from the command line is to disable the
use of the FBO extension, which has caused problems in the past with
Nvidia drivers:

The laptop at the show has only the JRE installed, so unless I missed
something, we'd need to run the web start demo.
(No, there's no alternate JNLP

OK, I've checked and it appears that we don't use the
DirectDraw scale loops for Bilinear filtering,
presumably because we can't control the filtering
algorithm when doing a DirectDraw stretch Blit.
The OpenGL pipeline handles it just fine, though.
As well as the upcoming Direct3D 9
But if you're really set on using the d3d pipeline,
here's another alternative, which may only work
on jdk6 and earlier releases.
1. set -Dsun.java2d.allowrastersteal=true
set -Dsun.java2d.accthreshold=0
set -Dsun.java2d.d3d=true (or for earlier
releases,
You can set the _JAVA_OPTIONS env variable to -Dsun.java2d.opengl=true
(or any other set of properties separated by spaces) in System
Properties/Advanced/Env.
Variables, so that all vms started on this system will pick it up.
Thanks Dimitri.
With that, I can confirm that the SwingSet2 demo
Did you try the 'fbobject' property Chris suggested?
Thanks,
Dmitri
