OpenGL Performance and Custom Cursors
Windows NT features custom cursors, such as decorated or animated cursors, in place of the
standard cursor. If you use a custom cursor while running an OpenGL program,
performance may decrease whenever you position the cursor in that program’s window. For
optimum performance of OpenGL programs, Intergraph Computer Systems recommends
that you use only the standard cursors.
Multiple Screen Display
If your system is set up for dual- or triple-screen display, the video display driver treats the
combined display area as a single canvas that covers all screens. In this Full Canvas style,
windows centered on the canvas are split between screens. This includes most system dialog
boxes. For details, see the video display adapter documentation and Help delivered with the
system, and the
README
.

files delivered with the video display drivers.
RenderGL Run-Time Library
The RenderGL run-time library is delivered with your TDZ 2000. This library is delivered
as a Dynamic Link Library (DLL) file. If you run an application that requires or uses the
RenderGL run-time library, you need to install the RenderGL DLL on your system.
The RenderGL DLL is delivered as follows:
•
Your system may have been delivered with a diskette containing the RenderGL DLL. If
so, see the
README
.
TXT
file on the diskette for installation instructions.
•
If your system was not delivered with a diskette containing the RenderGL DLL, you can
use the InterSite Version Manager to create the diskette. Run Version Manager from
the Welcome dialog that displays after you set up the operating system. After you create
the diskette, see the
README
.
TXT
file on the diskette for installation instructions.
