Property | Values | Definition |
j3d.rend | ogl ∣ d3d | Windows-only. Specifies which underlying rendering API should be used thus allowing both Direct3D and OpenGL native DLLs to be installed on a singe machine. Default: ogl |
j3d.deviceSampleTime | An integer | The sample time in milliseconds for non-blocking input devices. Default: 5 |
j3d.threadLimit | An integer | Controls how many threads may run in parallel regardless of how many cpu's the system has. Setting it to "1" will make the system act like a traditional OpenGL render loop. Default: number of CPUs plus one. |
j3d.disableXinerama | true ∣ false | Solaris only. Allows major performance boost when using dual screen environments with the X11 Xinerama extension enabled. Detailed information in the release notes. Default: false. |
j3d.displaylist | true ∣ false | OpenGL only. Enable use of display lists, an OpenGL performance enhancing feature. False to disable for debugging. Default: true |
j3d.g2ddrawpixel | true ∣ false | If true, use glDrawPixel to flush the graphics2D to the screen. If false, use texture mapping to flush the graphics2D to the screen. glDrawPixel is not accelerated on some older Windows video cards. Default: true |
j3d.sharedctx | true ∣ false | Shared contexts are used in OpenGL for DisplayLists and Texture Objects to improve performance. However some drivers have bugs causing weird rendering artifacts. This can be used to disable their use to see if this is the problem. Default: true for Solaris and false for Windows |
j3d.debug | true ∣ false | Prints out startup and running information. Useful for finding out information about the underlying hardware setup. Default: false |
j3d.vertexbuffer | true ∣ false | Use of vertex buffers, a D3D performance enhancing feature equivalent to OpenGL display lists. Some drivers have implementation problems so it might be worth turning this off if there are crashes. Default: true |
sun.java2d.d3d | true ∣ false | Windows only. Disable use of Direct3D by Java. Default: true |
sun.java2d.ddoffscreen | true ∣ false | Windows only. Disable use of DirectDraw and Direct3D by Java for off screen images, such as the Swing back buffer. Default: true |
sun.java2d.noddraw | true ∣ false | Windows only. Completely disable use of DirectDraw and Direct3D by Java. This avoids any problems associated with use of these APIs and their respective drivers. Default: false |
