speed up default application in C# with dedicated graph

  • 772

I have a development in C# and Winform for Windows which has an installer.msi

This development includes a web container that implements the library CefSharp; which I like for its low ram memory consumption.

The problem is that by default all the pages that I open are executed implementing the dedicated graphic; and I want that by default if there is a dedicated graphics card it will be pulled for hardware acceleration.

  1. In between investigating a solution is for the user to go and touch the GPU usage log in System and change the option to high performance:

enter image description here

So this doesn't really help me since I depend on the user having to make configurations or change on their device, so I have the following doubts:

Is there a way in C# to force the program to pull the dedicated graph if it exists for the execution of all processes and threads?

my program starts here:

using System;
using System.IO;
using System.Threading;
using System.Windows.Forms;
using System.Xml;

namespace Web_Desktop
{
    public partial class Loader : Form
    {

        public VarManager varManager = new VarManager();

        public Common commonClass = new Common();

        public XmlManager xmlManager = new XmlManager();

        public WebSelector webSelector;

        public Loader()
        {

            InitializeComponent();

        }

        public void StartUp()
        {

            
            bool filecheck = File.Exists(varManager.configfile);

            if (!filecheck)
            {

                if (varManager.isAdministrator)
                {

                    xmlManager.CreateConfXML();

                }
                else
                {

                    commonClass.RestartApp(true);
                    
                }

            }
            else
            {

                bool checkRunAs = false;

                XmlNodeList admSetting = xmlManager.ReadRunAS();
                XmlNode nodoAdm = admSetting.Item(0);

                if (nodoAdm.InnerText == "true")
                {

                    checkRunAs = true;

                }

                if (checkRunAs && !varManager.isAdministrator)
                {

                    commonClass.RestartApp(true);

                }
                else
                {

                    webSelector = new WebSelector(this);

                    Thread.Sleep(1500);

                    webSelector.ShowDialog();

                }
                
                

            }

        }

        private void Loader_Load(object sender, EventArgs e)
        {
            Thread thread = new Thread(StartUp);

            thread.Start();
        }

        private void Loader_FormClosed(object sender, FormClosedEventArgs e)
        {
            Application.Exit();
        }
    }
}

    Currently it is possible to speed up an application using native C# code but this requires a lot of code and extensive knowledge about the API from Intel, AMD and nvidia.

    For this project I chose to use another method; in which Windows configuration profiles are used.

    When starting the Application we can execute this code:

            private static void SetPerformance()
        {

            string keyName = @"HKEY_CURRENT_USER\SOFTWARE\Microsoft\DirectX\UserGpuPreferences\";
            string valueName = Assembly.GetExecutingAssembly().Location;

            if (Registry.GetValue(keyName, valueName, null) == null)
            {

                var key = Registry.CurrentUser.CreateSubKey(@"SOFTWARE\Microsoft\DirectX\UserGpuPreferences");
                key.SetValue(valueName, "AutoHDREnable=1;GpuPreference=2;");

                string subProccess = Application.StartupPath + @"\CefSharp.BrowserSubprocess.exe";

                key.SetValue(subProccess, "AutoHDREnable=1;GpuPreference=2;");
                MessageBox.Show("The app will restart.");

            }
        }

    which will add the application we want to speed up to the registry.

    As an addition to this I am also using CefSharp, I have had to add it to the Registry as well.
