I use minigl as it gives me very good quality and performance; it's the best if you want to use fsaa (no mouse lag and less blurred fonts)
I replaced the one from half-life with the latest one (1.49), in Half-Life\gldrv

default ICD is good to, it's the one to use with CS 1.6 (minigl doesn't work with it)
I play either in 800x600 with fsaa 4x (LOD -1.5, no mipmap dithering), or 1152x864 no fsaa (LOD -0.25, mipmap dithering)
