We all know the one and done method of Nvidia's G-Sync, where you enable both ULLM and Vertical Sync in the Nvidia Control Panel. Simple, no need to tinker with too much and can be applied globally.
As for AMD's Freesync I still confused how to set it up properly. I have read many forums and guides and I don't know what to stick with for AMD specifically. I'm mostly confused about one thing: the V-Sync Method
I have tested two configs that I think is the correct way to use Freesync, but I want another opinion. Which one of these is properly utilizes Freesync?
Config #1
AMD Freesync - AMD Optimized
Radeon Anti-Lag - Enabled
Radeon Enhanced Sync - Enabled
V-Sync Off In-game
Config #2
AMD Freesync - AMD Optimized
Radeon Anti-Lag - Enabled
Radeon Enhanced Sync - Disabled
Wait for Vertical Refresh - Off, unless application specifies
Frame Rate Target Control - (-3 Max Refresh Rate)
V-Sync On In-game
Optimal Freesync Settings?
Re: Optimal Freesync Settings?
I set and forget according to this recommended by AMD
https://www.amd.com/en/technologies/free-sync-settings
Use driver Vsync and In game Vsync off instead.
For input lag -3 Max Refresh Rate cap is what you want. Though I've seen some game doesn't like being RTSS capped. A Vsynced cap is absolutely fine. The input lag is totally negligible.
Other than those above config #2 is good.

Enhanced Sync is horrible terms of fluidity. Often times there'll be annoying micro stutters.Config #1
AMD Freesync - AMD Optimized
Radeon Anti-Lag - Enabled
Radeon Enhanced Sync - Enabled
V-Sync Off In-game
Use driver Vsync and In game Vsync off instead.
FRTC is not reliable as it doesn't work in some games. If you want a FPS cap use RTSS.Config #2
AMD Freesync - AMD Optimized
Radeon Anti-Lag - Enabled
Radeon Enhanced Sync - Disabled
Wait for Vertical Refresh - Off, unless application specifies
Frame Rate Target Control - (-3 Max Refresh Rate)
V-Sync On In-game
For input lag -3 Max Refresh Rate cap is what you want. Though I've seen some game doesn't like being RTSS capped. A Vsynced cap is absolutely fine. The input lag is totally negligible.

V-Sync On In-game
Cap fps using in-game engine if possible.
Average latency for fps caps sorted from best to worst:
in-game, driver cap, rtss
FPS cap depends on monitor refresh rate.
240hz = 192fps
165hz = 140fps
144hz = 124fps
120hz = 106fps

Re: Optimal Freesync Settings?
Why such an aggressive frame cap below refresh rate ? With Vsync On only 3 frames below refresh will be suffice for proper VRR.sky_dynasty wrote: ↑21 Jan 2024, 14:24

VRR used by g-sync and freesync displays needs 1ms of additional time to work.Stizzie wrote: ↑24 Jan 2024, 05:30Why such an aggressive frame cap below refresh rate ? With Vsync On only 3 frames below refresh will be suffice for proper VRR.sky_dynasty wrote: ↑21 Jan 2024, 14:24

240hz = 192fps
165hz = 140fps
144hz = 124fps
120hz = 106fps
real refresh rate when using variable refresh rate / g-sync / freesync
to get no tearing, you must add 1ms
1000ms (1 second) / 138fps (display refresh) = 7.246ms
7.246ms + 1ms (of freesync) = 8.246ms
new framerate therefore is
1000ms (1 second) / 8.246ms = 121.27fps
round down to nearest even number -> 120
240hz = 192fps
165hz = 140fps
144hz = 124fps
120hz = 106fps

Vsync coupled with VRR already taken care of tearing. Only a frame cap needed to ensure FPS never reach the VRR ceeling. I also noticed games paced better ( terms of frame time ) when Vsync enabled.

For Nvidia graphics cards:
Using the data given by the video I quoted above, when combining VRR with v-sync (in nvidia control panel), you only need to add 0.3ms of latency for VRR to work correctly. Therefore the FPS caps should be:
240hz = 233fps
165hz = 156fps
144hz = 138fps
120hz = 115fps
Reflex caps fps automatically when used with VRR and v-sync.
AMD graphics cards need 1ms additional time for VRR to work. Therefore the fps caps (if needed) are lower.
240hz = 192fps
165hz = 140fps
144hz = 124fps
120hz = 106fps
************************************
My display is 165Hz freesync premium. Fps cap should be 140. GPU - RX 6700 XT.
I tested some games using RTSS (frametime on in OSD, text, graph) to check for frametime variances. AMD Freesync and v-sync were turned on.
Rise of the Tomb Raider
Unstable frametime when fps between 142-146, both in full screen exclusive and borderless fullscreen.
vsync in amd adrenalin and in-game did not affect this range.
fps cap @ 140 fixed frametime variances.
Overwatch 2
Unstable frametime when fps between 142-146
fps cap @ 136 works best to remove frametime variances.
Far Cry: New Dawn
Unstable frametime when fps between 140-144
fps cap @ 136 works best to remove frametime variances.
Re: Optimal Freesync Settings?
That's not a source of information, that's a source of misinformation. That 1ms rule is utter nonsense.

Re: Optimal Freesync Settings?
Today I used G-SYNC Pendulum Demo to test my LG 27GP850-B 165 Hz monitor. My graphics card is AMD 6700 XT.
Below 165 fps, the bar showed no tearing. As soon as I set fps to 165 and above, there was some tearing.
Enhanced sync resulted in some micro stutters.
For the smoothest settings, I turned on v-sync and capped fps to 158 (I am going to use the same fps cap as Nvidia Reflex). When I let my fps go above my display refresh rate with v-sync on, the frametime displayed in RTSS was not stable.

Re: Optimal Freesync Settings?
The video card does not need any 1ms. I set amd chill min/max to 236 fps on a 240hz monitor, enable freesync, vsync in the driver and vsync in the game. This gives the smoothest picture possible with low input lag. There are no breaks or stutters. Otherwise, my computer is well configured and there are no stutters with vsync OFF, but there are image tearing.sky_dynasty wrote: ↑13 May 2024, 09:33Today I used G-SYNC Pendulum Demo to test my LG 27GP850-B 165 Hz monitor.
