Delphi TChromium, hidden rendering, how to reduce graphics quality and make it run faster?

Question

Delphi

Colleagues, please tell me how to improve browser performance by reducing quality and other bells and whistles in CEF?
Here is some code

begin
  if not DirectoryExists('.\cache') then
    ForceDirectories('.\cache');
  if not DirectoryExists('.\cookie') then
    ForceDirectories('.\cookie');

  INISetting := TINISetting.Create('.\setting.ini');

  CurrentParsingProject := TProject.Create;
  CurrentParsingProject.id := INISetting.Read('CurrentParsingProject', 'id', 0);
  CurrentParsingProject.name := INISetting.Read('CurrentParsingProject', 'name', '');
  CurrentParsingProject.comment := INISetting.Read('CurrentParsingProject', 'comment', '');
  CurrentParsingProject.create_at := INISetting.Read('CurrentParsingProject', 'create_at', '');

  GlobalCEFApp := TCefApplication.Create;
  GlobalCEFApp.EnableGPU := true;
  GlobalCEFApp.FastUnload := true;
  GlobalCEFApp.WindowlessRenderingEnabled := true;
  GlobalCEFApp.RemoteDebuggingPort := 9000;
  GlobalCEFApp.OnProcessMessageReceived := GlobalCEFApp_OnProcessMessageReceived;
  GlobalCEFApp.LogFile := 'debug.log';
  GlobalCEFApp.LogSeverity := LOGSEVERITY_INFO;
  GlobalCEFApp.Cache := '.\cache\';
  GlobalCEFApp.EnableHighDPISupport := false;
  GlobalCEFApp.Cookies := '.\cookie\';
  GlobalCEFApp.EnableMediaStream := false;
  GlobalCEFApp.SitePerProcess := false;
  GlobalCEFApp.IgnoreCertificateErrors := true;


  if GlobalCEFApp.StartMainProcess then
  begin
    Application.Initialize;
    Application.CreateForm(TFormMain, FormMain);
    Application.CreateForm(TFormSetting, FormSetting);
    Application.CreateForm(TFormProjects, FormProjects);
    Application.CreateForm(TFormNewProject, FormNewProject);
    Application.Run;
  end;

  GlobalCEFApp.Free;
  GlobalCEFApp := nil;
  INISetting.Update;
  INISetting.Free;
  CurrentParsingProject.Free;
end.

GlobalCEFApp is the framework's global application.
In which you can twist the settings.
What to turn off to improve the quality?
For example, disable image loading and so on...
