VolFix supports viewing charts via OpenGL.

The mode is activated in Market Watch - setup - Global Options - Use OpenGL = ON.

In OpenGL mode, the terminal works much faster and much more responsive.

OpenGL is enabled by default for the 32-bit version and disabled for the 64-bit version of the terminal.

Not all video cards support OpenGL. Here might be errors in the 64-bit version of Windows for the Intel and ATI video cards.

Before activating OpenGL, please make sure you have the latest video card drivers installed.
You can download your video card driver from the official web site:

To get video card OpenGL information use OpenGL Extensions Viewer.

If you have activated OpenGL and and error has occurred in VolFix, please either disable OpenGL or install the 32-bit version of VolFix.
