Richard Urban said something very well, with a bit of poetic flair just now,
Jessica, and I don't know your video card but I'd try these:
I wonder if your Video card has settings that you can modify by
right clicking the desktop>Personalize>Display Settings. You also might be
able to use the Acceleration level by pushing the setting all the way to the
right in the area of display settings.
This would be at Right Click desktop>Personalize>Display Settings>Advanced
Button>Troubleshoot tab.
You also may have a choice of screen refresh rate, and you should select (if
there is a choice) the most optimal refresh rate your chipset or card maker
advises.
Don't forget whoever made your card, for example BFG with NVidia chipset,
has very high quality tech support (unusual I know) so you could lean on
them.
The settings here are dependent on your video card and the particular driver
you choose for it.
Sometimes, though, you have a choice of drivers on the Nvidia or other
sites, and I recommend calling the card maker's Tech Support line because
those people are tracking the performance of the new drivers including the
Beta drivers in a variety of settings including different games and graphics
apps. They can tell you which of the drivers is working best if you have a
choice.
Obviously as time goes by, this variability will go away as more capable
stable drivers get released. Do check though the area of
Right Click desktop>Personalize>Display Settings>Advanced
Button>Troubleshoot tab.
Particularly look at acceleration, screen refresh rate and any settings your
nice new powerful card has on that Troubleshoot or another tab.
Good luck,
CH
