NvTrueHDR — RTX HDR for gaming

This page provides several tools to help you configure some of the hidden NVIDIA settings for HDR and DLSS.

# NvTrueHDR

You can use NvTrueHDR to enable RTX HDR at the driver level instead of the version used by NVIDIA that requires NVIDIA Overlay.

RTX HDR at the driver level can work with multiple monitors and can also be configured to lower "quality" settings to reduce significant performance degradation (a lower quality setting can also disable a degang filter that has been found to remove fine details in some cases).

NvTrueHDR currently works with most DX9/DX10/DX11/DX12 games, and can also support OpenGL/Vulkan.

NvTrueHDR requires 531.18+ and WDDM 3.1 (Win11+) drivers. (TrueHDRTweaks tested only with 551.23+)

# TrueHDRTweaks

TrueHDRTweaks is a plugin that you can apply to games to customize some of the advanced TrueHDR settings that are not available through the NVIDIA application/Profile Inspector.

For example, changing the "quality" level, disabling adaptive dimming, forcing HDR to set a certain value...

This can be used with any RTX HDR boot method (HDR at the driver level via NvTrueHDR or NVIDIA Overlay), but must be configured for each game to work. More information can be found in the FAQ section below.

# Using NvTrueHDR

• First, make sure that HDR is enabled on all connected displays and disable Windows AutoHDR.
• Download the main file and run NvTrueHDR.exe.
• Enter the name of the game's .exe file when prompted (you can drag the .exe file to the command prompt window).
• You will then be asked to select an action - select a quality level, select the "HUD" option to display the indicator in the game or disable it - make your choice and press Enter.
• (Very high quality significantly affects FPS, the difference between VeryHigh and Low is about 10%)
• We recommend that you select the "HUD" option first, so that the screen in the upper left corner displays squares that indicate that the function is active. Once you've verified that the feature works, you can turn it back on without the indicators (note that in some games the indicators may not be displayed, but the HDR effect will work - YMMV).
• The tool should tell you if the settings have been saved successfully. Now start the game, and hopefully everything should work.

Administrator privileges should not be required for this tool in most cases, but some settings may prevent non-administrators from changing settings. In this case, the tool will let you know.

For VK/OGL games, it may be necessary to change the "Vulkan/OpenGL present method" setting in the NVCP to "Prefer layered on DXGI swapchain" so that the HDR works properly.

The tool also supports some command line options in case you want to use it in scripts or launchers. Settings can be found in the usage section of the application.
