RTSSHooksCompatibility Sample

This repo is to show how its possible to disable RivaTuner Statistics Server (RTSS) from hooking your C# application by embedding a native static library that exports RTSSHooksCompatibility data. Currently with .NET you need to also enable NativeAOT to accomplish this.

Important

Do NOT do anything I do here unless you have a very important reason to disable RTSS hooking. This won't prevent users from using RTSS with your application as they can just set ForceHooking=1 in the [Hooking] section of either global or game specific profile.

While the sample here is using a MonoGame I made this sample for use in DLSS Swapper, a WinUI3/WindowsAppSDK application. In general I do not recommend disabling RTSS for your games as it can report useful information to your end users and you should only do this if you have specific reasons to disable RTSS hooking.

See my blog post here for how I came about all the source in this repo.

Build the static library

See RTSSHooksCompatibility folder.

Run build.cmd to build RTSSHooksCompatibility.obj. This requires VS2022 with the C++ module installed. If your install location is different to standard you may need to update the PATH in this file.

RTSSHooksCompatibility.c is the C source file which contains just the export.

Build the sample game

See MyAwesomeGame folder.

Assuming required MonoGame tools and .NET SDKs are installed you should be able to run publish.cmd which will produce two outputs in a folder called publish. One which will have RTSS enabled out of the box, one that explicitly disables it.

The changes in this project out of the standard MonoGame OpenGL template are as follows.

Changing

    <TargetFramework>net6.0</TargetFramework>

to

    <TargetFramework>net8.0</TargetFramework>
    <PublishAot>true</PublishAot>

and adding

<ItemGroup Condition="'$(Configuration)' == 'Release_RTSS_Disabled'">
  <NativeLibrary Include="../../RTSSHooksCompatibility/RTSSHooksCompatibility.obj" />
</ItemGroup>

Note

Condition="'$(Configuration)' == 'Release_RTSS_Disabled'" is not needed. I added that part so I can export with and without RTSSHooksCompatibility.obj.

Why is this using the standard MonoGame OpenGL Template?

More info can be found on pirota-pirozou/MonoGameNativeAOTTest. My understanding is that the DirectX version of MonoGame uses WinForms and WinForms does not support NativeAOT.
