Apex fullscreen & NVCP V-Sync behave differently than other games

Hey, quick question about how Apex handles fullscreen and V-Sync, because I’m seeing different behavior compared to other games on the same system.

My setup:

NVIDIA GPU

G-SYNC enabled (fullscreen + windowed)

V-Sync ON in NVIDIA Control Panel

In-game V-Sync OFF

Using NVIDIA FrameView to check sync status

What I’m seeing:

In Overwatch, FrameView shows V (V-Sync active) with the exact same driver settings.

In Apex Legends, FrameView always shows T (tearing), even though G-SYNC is enabled and I don’t see actual tearing on screen.

This makes it look like Apex isn’t presenting frames through a V-Sync-aware path, even when V-Sync is forced at the driver level.

I also noticed Apex doesn’t seem to be using true exclusive fullscreen:

Alt-tab is instant

No display mode switch

V-Sync state doesn’t get picked up by FrameView

So it feels more like borderless or flip-model fullscreen with its own frame pacing, possibly because of the engine or NVIDIA Reflex.

Question:

Is this expected behavior in Apex?

Does Apex intentionally bypass classic fullscreen and V-Sync, which is why tools like FrameView always report tearing even with G-SYNC and NVCP V-Sync enabled?

Just trying to understand if this is normal for Apex or something odd with the engine.

Thanks 👍
