Fixed Monitor Input Lag But I Have Questions (AW2723DF)

[Mach]

I'm not sure what you mean by break but my monitor seems to work with G-Sync on while testing, even at low FPS. G-Sync Indicator is on, the G-Sync setting is active, and even at 20 FPS, it continues to work.

I thought we could break it that way, by getting out of it's range. Any other ways you've found that are working for you?

I want to share something that might help others who are having desync and input lag issues in CS2, especially on very high refresh rate monitors.

My monitor is an AOC AGON PRO AG256FS (390Hz OC).
Since day one, I had noticeable desync and inconsistent input feeling in CS2. The game never felt truly 1:1, even at very high FPS.

Important detail:
On this monitor, FreeSync is OFF by default in the OSD, so I always kept it disabled.

At the same time, in NVIDIA Profile Inspector, I had manually set “G-SYNC Application State” to “Force Off” (I think this is IMPORTANT!), because I didn’t want any kind of VRR interfering with competitive play.

Here’s the key realization:

Because FreeSync was disabled in the monitor OSD, the G-SYNC option never appeared in the NVIDIA Control Panel. So I assumed everything VRR-related was fully off and irrelevant.

After reading more about this, I decided to test the following:

Enabled FreeSync in the monitor OSD

After doing that, G-SYNC finally appeared in NVIDIA Control Panel

I then unchecked / disabled G-SYNC in NVIDIA Control Panel

Left my usual competitive settings (V-Sync off, high FPS, etc.)

With this setup:

The game feels much smoother

Mouse input feels true 1:1

No more desync feeling

No noticeable input lag

So even though I am not using G-SYNC, simply enabling FreeSync at the monitor level (so the driver exposes G-SYNC properly) and then disabling it cleanly in the control panel seems to have fixed the issue.

It feels like forcing G-SYNC off at the driver level while the monitor reports no VRR capability might cause weird behavior or timing issues, especially at extreme refresh rates like 360–390Hz.

Just sharing this in case it helps someone else.

Alienware doesn't have GSYNCE in the OSD.

Exactly — that’s why. It means it’s enabled by default, just like on mine now(ON). What actually matters is disabling it in the NVIDIA Control Panel and, in NVIDIA Inspector, setting “G-SYNC Application State” to “Force Off”.

On my NVIDIA Control Panel, under 3D Settings, the “Monitor Technology” option shows as “Not supported for this option”… but it’s still enabled on the monitor OSD. Input lag/desync finaly free.

Tried this and it doesn't make a difference for me.

It also had negative effects (hit reg not as good as well as mouse movement) on my side. Freesync Premium is enabled by default in my Monitor settings (just for reference). And yes, it did show “Not supported for this option” after doing it as you mentioned.

I have an Alienware AW2525HM 320 Hz monitor that doesn’t have a G-Sync toggle in the OSD. After buying this monitor, I experienced several issues, including screen tearing and ghosting, which made the game almost unplayable.

For me, the best image quality and gameplay feel occur when:
1. G-Sync is enabled in “Set up G-Sync.”
2. In CS2 3D settings, Monitor Technology is set to Fixed Refresh.
* If I untick “Enable G-Sync” under “Set up G-Sync,” the game feels terrible.

After some research, I assume that VRR/Adaptive-Sync monitors need G-Sync to be enabled to some extent in order to display the image properly and stay synchronized with the GPU. This topic definitely needs further examination.
