¿Cómo puedo leer la carga de la GPU?

Question

Estoy escribiendo un programa que supervisa varios recursos de la computadora, como el uso de la CPU, etc. Quiero monitorear también el uso de la GPU (la carga de la GPU, no la temperatura).

using System; 
using System.Collections.Generic; 
using System.ComponentModel; 
using System.Data; 
using System.Drawing; 
using System.Linq; 
using System.Text; 
using System.Windows.Forms; 
using System.Diagnostics; 
using DannyGeneral; 


namespace CpuUsage 
{ 
    public partial class Form1 : Form 
    { 
     private bool processEnded; 
     private Process[] processList; 
     private string timeStarted; 
     private string timeEnded; 
     private List<float> processValues; 
     private bool alreadyRun; 
     private DateTime dt; 
     private DateTime dt1; 
     private PerformanceCounter theCPUCounter; 
     private PerformanceCounter theMemCounter; 
     private PerformanceCounter specProcessCPUCounter; 
     private float cpuUsage; 
     private float memUsage; 
     private List<float> Values; 

     public Form1() 
     { 
      InitializeComponent(); 

      processEnded = false; 
      processList = Process.GetProcesses(); 
      for (int i = 0; i < processList.Count(); i++) 
      { 
       listView1.Items.Add(processList[i].ProcessName); 
      } 
      processValues = new List<float>(); 
      alreadyRun = false; 
      dt = DateTime.Now; 


      Values = new List<float>(); 
       theCPUCounter = new PerformanceCounter("Processor", "% Processor Time", "_Total"); 
       theMemCounter = new PerformanceCounter("Memory", "Available MBytes"); 
       specProcessCPUCounter = new PerformanceCounter("Process", "% Processor Time", Process.GetCurrentProcess().ProcessName); 

       Logger.Write("The Program Started At *** " + DateTime.Now.ToShortTimeString()); 

     } 

     private void Form1_Load(object sender, EventArgs e) 
     { 

     } 

     private void timer1_Tick(object sender, EventArgs e) 
     { 
      memUsage = theMemCounter.NextValue(); 
      label1.Text = memUsage.ToString(); 
      Logger.Write("Memory Usage " + memUsage.ToString()); 
      cpuUsage = this.theCPUCounter.NextValue(); 
      label2.Text = cpuUsage.ToString(); 
      Logger.Write("Cpu Usage " + this.cpuUsage.ToString()); 
      Values.Add(cpuUsage); 
      isProcessRunning(); 
      if (alreadyRun == true) 
      { 
       processValues.Add(cpuUsage); 
      } 

     }

El video card's own CPU se llama GPU.

Busque contadores de rendimiento relacionados con eso o video (utilizando Start->Run->PerfMon o escribiendo PerfMon en la caja de búsqueda del menú Start; haga clic derecho en el gráfico y seleccione Add Counter...).

Si su fabricante de tarjeta de video no proporcionó ningún contador de rendimiento para la GPU, no hay ninguno para usted.
