Well I'm pretty sure the only file that would make a difference would be the nv4_disp.dll file itself but this is the main file anyways so I guess using a old nv4_disp.dll file with a newer driver might cause probs or if it works fine then I wouldn't see the changes made in the newer releases. xD

list of important files that are used in nvidia drivers

nv4_mini.sys = 1
nvcod.dll = 1
nvsvc32.exe = 1
nv4_disp.dll = 1
nvhwvid.dll = 1
nvoglnt.dll = 1
nvcpl.dll = 1
nvmctray.dll = 1
nvcpl.hlp = 1
nvwddi.dll = 1
nvnt4cpl.dll = 1
nvwcplen.hlp = 1
nvmccs.dll = 1
nvdisps.dll = 1
nvdispsr.dll = 1
nvgames.dll = 1
nvgamesr.dll = 1
nvmccss.dll = 1
nvmccssr.dll = 1
nvmobls.dll = 1
nvmoblsr.dll = 1
nvvitvs.dll = 1
nvvitvsr.dll = 1
nvwss.dll = 1
nvwssr.dll = 1
nvapi.dll = 1

To me without even have tried it out I'd say only that file would make any difference, the others doesn't seem to relate to d3d and such and I know nv4_disp.dll are used with directx based games so. Well it could be worth a try I guess but the thing is what benefit would it give me using 94.20 nv4_disp.dll file with v162.18 driver release for example?
