5–4 PowerStorm 300 AGP and 300/350 PCI Graphics Controllers
Tearing and flickering can occur for a combination of reasons:
•
Many large triangles are being processed.
•
A large window is being used.
•
High resolution and refresh rate values are defined.
Most applications do not experience visual tearing and could take advantage of the higher
frame rates and better performance available when no synchronization is used. Therefore,
you should try using this mode.
If unwanted visual effects do occur, however, use the tear-free (sync with refresh) double-
buffering mode, choosing the highest vertical refresh rate supported by your monitor at
your chosen resolution (see Section 5.2.1).
You can change the double-buffer synchronization mode using the display applet, as
described in Section 5.2.2.1.
5.2.2.1 Using the Display Applet
To use the display applet, follow these steps:
1.
From the desktop, choose My Computer.
2.
Choose Control Panel.
3.
Choose Display.
4.
Select REALimage Settings.
5.
In the REALimage section, select the check box Minimize Flicker (sync swap with
retrace) to synchronize with the vertical refresh, or turn off the check box to disable it.
6.
When prompted, press OK to reboot your workstation.
When you use the REALimage application to set the double-buffer synchronization mode,
this definition remains effective across reboots until changed.
5.2.3 Identifying the Display Driver Version
If you encounter a problem with the PowerStorm display driver, you can report it to
Compaq. When reporting a problem, you must include the version of the driver with your
description of the problem.
To identify the version of the display driver, follow these steps:
1.
Select Start, Programs, and Windows NT Explorer to view the files currently installed
on your machine.
2. To ensure that all files are listed, select View, Options, and the View tab, and verify
that the Show all Files box is selected. Choose OK.
