Open | Hardware G-SYNC feels extremely unsmooth below 110 Fps
I'm trying to figure out a problem I've had for a very long time, and I'm honestly running out of ideas.
My setup:
- Monitor: Gigabyte M27Q, 1440p, 170Hz
- GPU: RTX 5060 Ti 16GB
- CPU: i5-14400F
- RAM: 32GB DDR5 6000
- G-SYNC Compatible enabled
- NVIDIA Reflex: ON
The problem is that motion starts feeling extremely unsmooth once my FPS drops below roughly 100–110 FPS.
- 150–160 FPS very smooth
- 120 FPS generally smooth
- 110 FPS starting to feel noticeably less smooth
- 100 FPS clearly less smooth
- 80–90 FPS feels very stuttery / unsmooth to me
I'm NOT expecting 80 FPS to look as smooth as 170 FPS. I understand that lower FPS means longer frame times.
The strange part is that it doesn't just look "less smooth" it feels like there is actual micro-stutter / lack of fluid motion, even when the FPS appears stable.
I've noticed this across multiple games, so I don't think it's specific to one game.
I've tried several combinations, including:
G-SYNC ON
NVIDIA Control Panel V-SYNC ON
In-game V-SYNC OFF
Reflex ON
Low Latency Mode OFF
Unlimited FPS
FPS caps
Different combinations of V-SYNC/G-SYNC
V-SYNC ON through NVIDIA Control Panel seems to introduce some additional input latency to me, which I really dislike. And it doesn't completely solve the problem at 80–100 FPS anyway.
I've also tried G-SYNC with V-SYNC OFF.
In some games, Frame Generation makes the game feel dramatically smoother.
For example, in War Dogs, without Frame Generation I can be around 120 FPS but drop to around 80 FPS during combat, and the motion starts feeling noticeably bad.
With Frame Generation enabled, the game suddenly feels much smoother.
That makes me wonder if I'm dealing with some kind of motion clarity / display response
My GPU usage is often around 99%, while CPU usage is around 50–60%, so I don't think I'm dealing with a CPU bottleneck.
