Adjusting framerate w/o an AMD card

Talk about AMD's FreeSync and VESA AdaptiveSync, which are variable refresh rate technologies. They also eliminate stutters, and eliminate tearing. List of FreeSync Monitors.

Adjusting framerate w/o an AMD card

Post by rofer » 10 Apr 2018, 09:01

I'm looking to buy a Freesync monitor and I currently have an NVIDIA card. Is it possible to set the monitor to refresh at a constant rate that isn't it's maximum?

I'd like to have tear-free gaming so I will be using v-sync, but at 1440p I won't be able to hit the 144Hz the monitor I'm looking at supports. I'd like to try playing a game, figure out what refresh rate I can reasonably hit, then set the monitor to that. Kind of like a poor-man's g-sync/freesync.

Eventually I'll have a machine with an AMD card and just use freesync, but I'd like to know what my options are until then.

Most gaming monitors can operate at any refresh rate you want. All you need to do is use CRU to add the refresh rate you want. I used to do this when I didn't have a gsync monitor yet, and had added 75Hz and 90Hz modes.

Some monitors will not properly support this and will frame skip, but this is very unlikely with freesync monitors.

Yes - generally FreeSync monitors are very multisync.

Usually, any Hz in the VRR range can be created as a fixed Hz. It may sometimes have to derive from a specific dotclock, but success rates of custom refresh rates are very high on FreeSync panels.
