Hi Alex, My Video card is a Nvidia k2100M with 2 Gb of dedicated memory. I set up a profile for PhotoLab in the Nvidia Control Panel and set anisotropic filtering to off and that corrected my problem. In addition doing this really speeds up my folder to folder loading and image displaying times. I also use Fast Raw Viewer and set the profile for it to application controlled so it would load and display DNG files properly as it was giving me nags about Anisotropic filtering being on.
Hope this helps
Larry
