When I installed Dungeon Siege2 on my new Windows 10 machine, with a NVIDIA GeForce GTX 680 graphics card, I found that the Nvdia Control Panel (where you set Anistropic filtering, etc.) did not work properly. It did a great job with the characters and objects, but did not recognize the terain (nodes). It looked God awful. I did some research and found the Nvidia Profile Inspector.
I used this to set the graphics for the DS games got the best possible with them. It has many complex and obscure settings not available on the control panel, and also a long list of games and their optimal settings. The Nvidia Profile Inspector may be what you need for your older games, or to go beyond the settings available on the Nvidia control panel.
