Most of the utilities posted here for "Tweaking" the refresh rate
DO NOT WORK for the latest nvidia drivers and may cause problems
with your 'puter if you use them
Read the entire information on tweak utilities before you use them
Get the latest drivers from nvidia. I believe that the latest
"Detonator" drivers allow higher refresh rates
I installed the latest drivers and now my nvidia software
shows 85 hz refresh rate just like my monitor settings
windows will allow you to set your monitors refresh rate
to whatever your monitor will run
the nvidia drivers will only allow a max of 60hz
tweaking of the nvidia drivers to 85 hz is the key
with the new nvidia drivers you can do this in the nvidia
controls - previous versions of the nvidia drivers would
only allow a max refresh rate of 60hz
the tweaks that have been posted here are not
designed to work on the latest nvidia drivers
