G-Sync + NULL

Talk about NVIDIA G-SYNC, a variable refresh rate (VRR) technology. G-SYNC eliminates stutters, tearing, and reduces input lag. List of G-SYNC Monitors.

G-sync + V-sync ON + NULL

In the above scenario, will the frame-rate always be capped below the refresh rate, even in DX12 / Vulkan games that ignore the MPRF setting? And will they do so only with G-Sync enabled (i.e. only in full-screen mode)?
Whether the auto FPS limiter of G-SYNC + NVCP V-SYNC + Low Lantency Mode "Ultra" will engage is game-dependent. It also typically doesn't engage in DX12 or Vulkan.

I had previously done a test of some of my own games at one point to see when it would and would not engage:
G-SYNC + NVCP V-SYNC + LLM Ultra @165Hz

158 FPS Auto Limit:


– Amid Evil (DX11)
– Battlefield 1 (DX11)
– Control (DX11)
– Counter-Strike: Global Offensive (DX9)
– Deus Ex: Mankind Divided (DX11)
– Hollow Knight (DX11, Unity)
– Journey To The Savage Planet (DX11)
– Overwatch (DX11)
– Tom Clancy’s The Division 2 (DX11)
– Valorant (DX11)
– We Happy Few (DX11)

No 158 FPS Auto Limit:


– Battlefield 1 (DX12)
– Call of Duty Warzone (DX12)
– Control (DX12)
– Deus Ex: Mankind Divided (DX12)
– Doom 2016 (Vulkan & OpenGL 4.5)
– Doom Eternal (Vulkan)
– Journey To The Savage Planet (DX12)
– Outward (DX11)
– Tom Clancy’s The Division 2 (DX12)
– Yooka-Laylee and the Impossible Lair (DX11, Unity)
Basically, it's not reliable as a global framerate limiter, since it doesn't always apply to every game.

You can achieve virtually the same thing globally with G-SYNC by using G-SYNC + NVCP V-SYNC + LLM "On" (note: LLM won't engage in all games, and not in DX12 or Vulkan at all) + manual NVCP Max Frame Rate FPS limit.

Even when I have Ultra Low Latency mode “off” it still auto limits fps when I have gsync and NVCP vsync on. Any idea if a recent Nvidia Driver update made it so that no matter what your ULL setting is your fps is capped if you have gsync and NVCP vsync enabled? Although I’m only losing 12 fps since it would be at 237 without the auto limit It’ll be nice to have the extra frames.

Do you have Reflex enabled? Because it also automatically limits the max framerate to ~224 at 240Hz with G-SYNC + V-SYNC.

I tested g-sync on, NVCP v-sync on, ULL off, and reflex disabled in-game but it still capped my fps at 225. This happened on Destiny 2 and Fortnite. However on Apex Legends even with ULL on and reflex + boost enabled in-game it doesn’t auto limit the fps to 225.
I wonder if enabling g-sync and v-sync NVCP simultaneously regardless of ULL or reflex settings automatically caps the fps on certain games.

If you truly have LLM and Reflex "Off" (and you don't accidentally have an Nvidia Max Frame Rate, RTSS or in-game limit in place) and are still experiencing the ~224 FPS auto limit with G-SYNC + V-SYNC, it must be a glitch in the affected games (and/or the driver install).

Also, G-SYNC + NVCP V-SYNC is typically required for the auto limit to take effect, at least with Reflex. I.E. G-SYNC + in-game V-SYNC may not always cause Reflex to auto limit the framerate, depending on the game.

Again, short of a glitch, not in my experience, and not that I know of.

from what Ive seen NULL and Reflex doesnt do anything better than a framelimiter below refreshrate.

Did you have time to thoroughly test Low Latency Mode for DX12. On my side games work without a hitch, always 138 cap when set to Ultra. Hoping that same would be done for Vulkan since Ultra Low Latency feels more natural to use with G - Sync for me...
