If you already have low FPS you might begin to experience micro stutters. Essentially, changing Low Latency Mode to Ultra removes a rendering buffer that usually assists in providing smooth gameplay. If your hardware is a bit older or not very strong, you might actually be hindered by changing this to Ultra. Here's a video describing Response Time vs Input Latency as well Input latency can range from ~20ms - 45ms generally and changing this setting can significantly improve those numbers You might be aware of monitor "Response Time" and graphic "Input Latency", this setting effects the latter. It was added to the control panel about a year ago? And its "off" by default. This setting is awesome and I can't believe I didn't know about it until now. NOTE: Clicking the Restore Defaults link at the top of the page will restore all the defaults for the entire Manage 3D Settings page.Right click on your desktop -> Nvidia Control Panel -> Manage 3D Settings -> Low Latency Mode -> Set to Ultra

To restore the default settings for a global preset (workstation products), select the global preset and then click the Restore button that is adjacent to the Global Presets list. To restore the default global settings, click the Restore button on the bottom corner of the Global Settings tab.

In the Settings box, click the setting corresponding to the feature that you want to change, then from the drop-down list click the setting value that you want to use. The Global Presets list does not appear for GeForce products.

If you have an NVIDIA Quadro product installed, then click the Global Presets list arrow and select one of the pre-installed global settings for workstation applications.

The Global Settings tab allows you to assign global settings that will be applied to all 3D games. From the NVIDIA Control Panel navigation tree pane, under 3D Settings, select Manage 3D settings.
