Thx to both Iam2 and Jaguar for your replies. Installed latest drivers and see a slider in the
driver control panel to adjust between performance and quality. I chose the middle of that slider
which Nvidia refers to as Balanced. There are other custom settings but have
no idea how to adjust to use less PC resources. I installed the 266.58 Driver package. Got
BSOD once in a while in the past now wtg for new Ram to arrive by mail. Going from 256 to
1024. Maybe this will help.
