I am experiencing slow screen refresh rates with other apps outside of SW and running Win XPP SP2. This has just lately become a problem. I am looking to try the latest graphics driver compatible with SW, but I get conflicting info on nVidia and Solidworks sites. nVidia shows the latest certified drivers as 84.26 and the latest (uncertified ?) driver as 162.65, while SW shows the latest as 6.14.11.62.65. Is the 6.14.11.62.65 a vNivdia 162.65 that has been tweaked? Which is the best to use for overall system performance? TIA
