OpenGL Driver Issues

• It is common for the Win2000 and WinXP operating systems to contain OpenGL driver implementations that have bugs. Some drivers are 100% software. Other drivers contain software with video card firmware. If any part of the system has bugs, then programs that use OpenGL (like VTube) will probably show issues or even fail at some point.

• Typical problems are stray lines on the screen, floating point error messages, or the graphics viewpoint acts in some strange way. Sometimes you may not be able to perform a selection.

• In every case so far, the issue can be resolved with an OpenGL update.

GLview

• We recommend that you use the OpenGL Viewer from Realtechvr called GLview to check to be sure your system has the latest video card drivers (which includes OpenGL drivers). Even if the drivers work fine, the newer drivers will sometimes increase the speed of OpenGL significantly - so a check for newer drivers is a good idea in most cases.

• Download the viewer from this page: GLview Download Page

• Select the options that pertain to your setup like shown below, then press Download.

• Install the program. It will look like this:

• Use the program to help you check for the latest OpenGL driver for your video card.
