Video Card; Graphics Acceleration - Tascam PCI-822 User Manual

Video card

Many video cards hog the CPU or the PCI bus in order to improve
their own performance. This can be at the expense of good real-time
performance, which is critical for digital audio workstations.
Check the manufacturer's web site frequently to make sure you're
using the latest drivers for your video card. Simply updating the video
card drivers can eliminate problems and dramatically improve
performance.

Graphics Acceleration

If you experience glitches during recording or playback, you may have
a video driver problem. If so, try reducing the amount of graphics
acceleration used by Windows. Open the Control Panel, double-click
the System icon, select the "Performance" tab in the System
Properties dialog, and click the "Graphics..." button. When the
"Advanced Graphics Settings" dialog appears, move the "Hardware
acceleration" slider all the way to the left. Click "OK" to confirm the
setting, and close the Control Panel. After changing this setting, you'll
be reminded that the new settings won't take effect until you restart
Windows.
After you've rebooted, see if the glitching problem is gone. If so, you
may want to experiment with other settings of the "Hardware
acceleration" slider to regain some of the graphics performance.
