Well the artifacting may not be preventable in that old card...but the new control panel interface is an
added interface...you don't have to use it, just click the tab at the top called "advanced control panel" or something like that & it switches back to the old style

in other words, you have two control panels to choose from, the old one & the new one.
For my 7900 & I would imagine the old 7800's I had, these drivers flat out rock.
