If you play competitive games like Valorant, Call of Duty: Warzone, or Counter-Strike 2, you have probably seen the Low Latency Mode option inside the NVIDIA Control Panel. Many gamers assume it boosts FPS, but that is not actually its main purpose.

NVIDIA Low Latency Mode is designed to reduce input lag by controlling how frames are queued between the CPU and GPU. In fast-paced shooters, even a few milliseconds can affect aiming responsiveness and overall gameplay feel.
This guide explains exactly what Low Latency Mode does, how the Off/On/Ultra settings work, whether it affects FPS, and when you should use it instead of NVIDIA Reflex.
What Does Low Latency Mode Do in NVIDIA Settings?
Low Latency Meaning — The Core Concept Explained
Players often confuse input latency with internet ping, but the differences are explained clearly in Does Internet Speed Affect FPS? FPS vs Ping Explained.
In gaming, latency refers to the delay between your input and the action appearing on screen. When you click your mouse, there is a short processing chain:
- CPU prepares the frame
- GPU renders the frame
- Monitor displays the image
This process creates what is called render latency.
Normally, games allow multiple frames to queue ahead for smoother throughput. This queue helps maximize GPU efficiency and FPS, but it also increases input delay.
NVIDIA Low Latency Mode reduces the number of queued frames, lowering the delay between your mouse movement and what you see on screen.
The relationship works like this:
- More queued frames = higher FPS potential but more input lag
- Fewer queued frames = lower latency but potentially lower GPU efficiency
This is why competitive gamers often prioritize lower latency over maximum FPS.
What Is Low Latency Mode in the NVIDIA Control Panel?
You can find the feature here:
NVIDIA Control Panel → Manage 3D Settings → Low Latency Mode
The setting controls the GPU render queue depth, also known as pre-rendered frames.
By default, the option is set to Off, meaning games manage frame queuing automatically. You can apply Low Latency Mode globally or configure it per game.
Low Latency Mode Options — On, Ultra, and Off Explained
Low Latency Mode Off — What Happens?
When Low Latency Mode is Off:
- The game controls render queue depth
- Up to 3 frames may be queued
- GPU efficiency remains highest
- FPS can be slightly higher
This setting is often best for:
- CPU-bound systems
- Casual gaming
- Games with built-in latency optimization
If your GPU usage stays below 70%, enabling Ultra usually provides little benefit.
Low Latency Mode On — What Does It Do?
The On setting limits pre-rendered frames to 1.
This reduces input lag while keeping GPU utilization relatively stable.
Best use cases include:
- Competitive shooters
- Mid-range GPUs
- 144Hz gaming
- GPU usage around 80–90%
You may see a tiny FPS reduction in some games, but responsiveness usually improves.
Low Latency Mode Ultra — What Does It Do?
Ultra mode uses just-in-time frame submission.
Instead of queueing frames ahead, the driver sends frames only when the GPU is ready to render them. This achieves the lowest possible driver-level latency.
Benefits:
- Maximum input responsiveness
- Best for high-refresh-rate monitors
- Ideal for GPU-bound systems
Potential downside:
- Slight FPS reduction when GPU usage is already very high
- Less effective on CPU-limited PCs
Low Latency Mode On vs Ultra — Side-by-Side Comparison
| Setting | Pre-Rendered Frames | Input Lag Reduction | FPS Impact | Best Use Case |
| Off | Up to 3 | None | Highest FPS | Casual gaming / CPU-bound systems |
| On | 1 | Moderate | Slight reduction | Competitive gaming |
| Ultra | Just-in-time | Maximum | Minor reduction possible | GPU-bound esports gaming |
Does Low Latency Mode Affect FPS?
If you are unsure how your hardware affects gaming performance, our What FPS Can I Get on My PC? — How to Check, Estimate & Boost Your Frame Rate guide can help you estimate expected frame rates before adjusting latency settings.
Does Low Latency Mode Increase FPS?
No. Low Latency Mode is not designed to increase FPS.
Its primary goal is reducing input-to-display delay.
In some scenarios:
- GPU-bound systems may lose a few FPS in Ultra mode
- CPU-bound systems often show almost no FPS difference
- Competitive players may prefer lower latency even with slightly lower FPS
Does Low Latency Mode Affect Graphics Quality?
No. It does not change:
- Texture quality
- Resolution
- Shadows
- Ray tracing
- Shader quality
The feature only adjusts frame pacing and render queue timing.
Does Low Latency Mode Affect FPS Stability?
Sometimes.
Reducing queued frames can improve frame pacing consistency, especially when GPU utilization stays near 90–100%.
However, if the GPU becomes overloaded, Ultra mode may introduce small FPS fluctuations.
Is Low Latency Mode Good for Gaming?
When Low Latency Mode Is Worth Using
Low Latency Mode works best for:
- Competitive FPS titles
- 144Hz or 240Hz monitors
- GPU-bound gaming systems
- Fast-response gameplay
Popular examples include:
- Valorant
- Call of Duty: Warzone
- Escape from Tarkov
- Counter-Strike 2
When Low Latency Mode May Not Help
In some systems, performance bottlenecks are caused more by memory limitations than render queue latency, which is explained in Does RAM Affect FPS in Games?
You may not benefit much if:
- Your GPU usage is below 70%
- The game already supports NVIDIA Reflex
- You mainly play single-player games
- Maximum FPS matters more than responsiveness
Should Low Latency Mode Be On or Off? — Recommended Settings by Use Case
| Use Case | Recommended Setting |
| Competitive FPS games | Ultra |
| Tactical shooters | On or Ultra |
| Casual single-player gaming | Off |
| Low-end CPU-bound PC | Off |
| High-refresh-rate monitor | Ultra |
| Game with NVIDIA Reflex | Off (use Reflex instead) |
Low Latency Mode vs NVIDIA Reflex — What Is the Difference?
What Is NVIDIA Reflex?
NVIDIA Reflex is an in-game technology that reduces latency at the engine level instead of through the driver. NVIDIA Reflex is an in-game technology that reduces latency at the engine level instead of through the driver.
Because Reflex integrates directly with the game engine, it usually works better than Low Latency Mode.
Supported games include:
- Valorant
- Fortnite
- Apex Legends
- Escape from Tarkov
What Is Render Latency in NVIDIA Reflex?
Render latency is the delay between:
- CPU submitting the frame
- GPU completing the render
Reflex actively minimizes this delay and can display measurements using NVIDIA’s performance overlay.
Low Latency Mode vs NVIDIA Reflex — Comparison Table
| Feature | Low Latency Mode | NVIDIA Reflex |
| Location | NVIDIA Control Panel | In-game settings |
| Works Level | Driver | Game engine |
| Precision | Moderate | High |
| FPS Impact | Minor | Minimal |
| Compatibility | Most NVIDIA-supported games | Reflex-supported titles |
Should You Use Both Low Latency Mode and NVIDIA Reflex Together?
Usually no.
NVIDIA generally recommends:
- If Reflex is available → set Low Latency Mode to Off
- Use Reflex instead for best latency reduction
Running both together can create frame scheduling conflicts.
Game-Specific Low Latency Mode Settings

Conclusion — Should You Use NVIDIA Low Latency Mode?
Final Verdict — Low Latency Mode Summarized
NVIDIA Low Latency Mode reduces input lag by limiting the GPU render queue. It does not improve graphics quality or directly increase FPS, but it can make gameplay feel more responsive.
Ultra mode offers the strongest driver-level latency reduction, especially in GPU-bound competitive games. However, NVIDIA Reflex remains the superior solution whenever supported in-game.
If your favorite game lacks Reflex support, Low Latency Mode Ultra is usually the best alternative for competitive play. Before changing settings, it is smart to benchmark your expected FPS first so you can understand whether your system is GPU-bound or CPU-limited.
