I have a 4650 1Gb which has always been upto the job of running QL as well as I'd need it to until I upgraded my monitor at christmas to a 2233rz samsung (120hz). I had to upgrade the drivers to be able to run 120hz. Since then I've noticed a drop in performance. I'm using version 10.12.
Can anyone recommend me a better or more suitable version for my card that will still have no problems in running 120hz?
Thanks
