Freesync on non-freesync

[Pieter Van Oeckel]

Hello guys, i got a question about Freesync and monitors. I maybe want to install a AMD gpu into my new build but can i use freesync with a non-freesync monitor. Since freesync is not a physical module like g-sync, i thought that you could just install some software to get freesync

Yes... But only in some cases... You can find more info here...

I think its a beta project or something ike that...

Catalyst & crimson drivers have a dynamic vsync option which works the same as nvidia adaptive vsync.

Locks vsync at native htz, but disables it on the fly if fps drops below.

Its not freesync but it works well enough on any standard monitor.

Didn't know it was now in the newer drivers. I was recommending RadeonPro before.

If not clear, the point of this is to prevent STUTTERING if you drop below the VSYNC FPS (i.e. 60FPS for 60Hz monitor). That will introduce screen tear instead which is often the lesser of two evils.

You should generally tweak game settings if using so that drops are minimal. Maybe 5% of the time but it also depends on how noticeable screen tearing is.

FREESYNC:
I tried to read the links in the first post but it sounds like a hit-or-miss thing with edited drivers.

*Also, you want the Freesync range to be a minimum 2.5x ratio (i.e. 30Hz to 75Hz thus 75/30). If not then you drop out of Freesync on the low end and revert to VSYNC ON (stutter) or VSYNC OFF (screen tear).

So even if you know what you're doing it's not likely to work well. If you had a range of 40FPS to 60FPS you have to stay in that range only. Drop below and I discussed already. Go above and the latency increases so the game lag keeps changing as you go in and out of this zone.

So DYNAMIC VSYNC is arguably the best solution, though not needed if you aren't dropping below the VSYNC target.

If you look for an official Freesync monitor then make sure it's at least 2.5x as discussed. MOST of the ones that are under 100Hz are not.
