Enabling ultra-low latency mode for NVIDIA graphics



  NVIDIA GeForce RTX 2080 SUPER Graphics Card

The NVIDIA graphics drivers now provide an ultra-low latency mode for competing players and anyone looking to play in their games want fastest response times for input. This feature is available for all NVIDIA GeForce GPUs in the NVIDIA Control Panel.

What is the extremely low latency mode?

Graphics engine queuing frames to be rendered from the GPU, the GPU renders them and they are then displayed on your PC. As NVIDIA explains, this feature builds on the Maximum Pre-Rendered Frames feature found in the NVIDIA Control Panel for over a decade. That way, you could keep the number of frames in the render queue low.

Ultra-Low Latency mode transfers frames to the render queue before the GPU needs them. This is just-in-time frame scheduling, as NVIDIA calls it. NVIDIA states that latency can be increased by up to 33% by using the Maximum Number of Pre-Frames Allowed [reduce] option.

This works with all GPUs. It only works with DirectX 9 and DirectX 11 games. In DirectX 12 and Volcano games, "the game decides when the frame will be queued", and the NVIDIA video drivers have no control over it.

This tells NVIDIA that you want to use this setting:

"Low Latency Modes If your game is GPU-bound and the frame rates are between 60 and 100 FPS, you have the most effect. This gives you the responsiveness of high-frame-rate games without sacrificing visual fidelity. "

In other words, if a game is CPU-bound (limited by your CPU resources instead of your GPU), or you have very high or very low FPS, that does not help much if you have an input latency in games For example, mouse delay, this is often simply a result of low frames per second (FPS), and this setting does not solve the problem.

Warning : This may reduce your FPS Mode is disabled by default, which, according to NVIDIA, results in "maximum render throughput." This is usually a better option for most users, but you should take advantage of all the small advantages of competitive multiplayer gaming – and less latency

Enabling Ultra Low Latency Mode

You need NVIDIA version 436.02 or a newer version video driver to use this Update the GeForce Experience application or download the latest video driver directly from the NVIDIA website.

Then start the NVIDIA Control Panel. To do this, right-click on your Windows desktop and select "NVIDIA Control Panel".

 Starting the NVIDIA Control Panel

On the left sidebar, under 3D Settings, click Manage 3D Settings. [19659008] Select how you want to enable Ultra Low Latency mode. To enable it for all games on your system, select "Global Settings". To enable it for one or more specific games, select "Application Preferences" and select the game you want to activate it for.

 Managing 3D Settings in the NVIDIA Control Panel

Look for "Low Latency Mode" in the list of settings. Click the settings box to the right of the setting and select "Ultra" in the list.

With the default Off, the game engine queues one to three frames at a time. The On setting forces the game to queue only a single frame. This is equivalent to setting Max_Prerendered_Frames to 1 in older NVIDIA drivers. When set to Ultra, the frame is sent "just in time" for the GPU to pick it up. There is no frame in the queue.

 Enabling Ultra Low Latency Mode for NVIDIA Graphics [19659008] Click the Apply button to save your settings. You can now close the NVIDIA Control Panel.

Note that this option may affect performance in many situations. We recommend activating it only for specific games and testing your settings to see how well it actually works.

If you want to undo your changes and use the default NVIDIA graphics driver settings, go back here and click the "Restore" button. [19659030]! Function (f, b, e, v, n, t, s)
