So I managed to make V-Sync work with Dynamic MFG

After some trial and error, I managed to get it working. There is a slight "grey area" between the maximum FPS provided by V-Sync + Reflex and your desired target FPS where performance can fluctuate, but this seems rare - and if your monitor has a high refresh rate, it's even less noticeable.

Setup Instructions (Note: I am using NVIDIA Profile Inspector, not the NVIDIA App):

1. Enable G-SYNC + V-Sync: Turn both on for the specific game via the NVIDIA Control Panel.
2. Update DLLs: Replace both the NVIDIA Streamline (v2.11) and DLSS (v3.10.6) DLLs in the game folder. (I recommend using DLSS Swapper for full control but there are pother ways). You can download the Streamline files here.
3. NVIDIA Inspector Settings: My monitor is 120Hz. When Reflex and G-SYNC are active, the FPS automatically caps at 116. I chose a target of 110 FPS (6 FPS below that cap) to ensure stability and allowing the feature to kick in.

Understanding Dynamic Frame Generation Count: Set your cap at the maximum multiplier needed to hit your screen's refresh rate in the "worst-case scenario" (the most demanding parts of the game).

• In my case: At my current graphics settings, a 3x multiplier consistently hits the 116 FPS cap. However, if I switch to 2x, intense scenarios cause the frame rate to drop to the 90–100 range.

Observations on the Algorithm: The Dynamic MFG is very "strict" about meeting your target. If there is even a small chance the frame rate might dip below 110 FPS, the algorithm stays at 3x to be safe. Even if the actual performance could technically sit 10–20 FPS above your target, you won't see it because V-Sync caps the output at 116.

In less demanding areas, you will see the MFG multiplier drop to 2x. With a 3x cap on a 120Hz monitor, the "base" frame rate range required to trigger a switch between 2x and 3x is quite narrow. The algorithm currently favors a guaranteed target over frequent switching; perhaps NVIDIA will refine this in future driver updates.

Testing Results: I tested this in Crimson Desert, Star Wars Outlaws, and Death Stranding 2 by enabling the DLSS GUI via registry key. I can definitely see the multiplier dropping to 2x in lighter areas - be aware you can also know its active because you will see "Dy" (I assume it means dynamic) in the top and the desired fps like this ->110hz

Pro Tip: If you want to force a drop to 2x to verify it's working, try lowering your DLSS scale. I usually run at 4K DLSS Quality (very demanding), which keeps the game at 3x. If I switch to Balanced, the base performance improves enough that 3x is no longer needed to hit the target, and the multiplier drops to 2x.
