Geforce 6200 LE is a card from 2004, are you looking at modern specs for the versions of the games on Steam? Quake was originally released with only a software renderer and later GLQuake was released with OpenGL support, that only really ran well initially on 3DFX Voodoo cards, although technically I think S3 Verge and some other 3D accelerators were supported. Quake 2 supported 3D accelerators at launch but also had a software renderer, like many notable PC games of the late 90s (Half-Life, Unreal tournament, Deus Ex, etc). Quake 3 was controversial in 1999 for being one of the first major PC games that required a 3D accelerator, among other things, the term GPU didn't really get used for PC graphics cards until Nvidia released the Geforce 256.
