Hello, I’am using Profile-Guided Optimization (PGO) with Unreal 5.7.1. in Win64

I could genereate *.pgd/.*pgc file with

  1. using following target.cs to build shipping sln, and i can generate *.pgd file
public class ThirdPerson : TargetRules
{
	public ThirdPerson(TargetInfo Target) : base(Target)
	{
		Type = TargetType.Game;
		// DefaultBuildSettings = BuildSettingsVersion.V5;

		ExtraModuleNames.AddRange( new string[] { "ThirdPerson" } );
		
		DefaultBuildSettings = BuildSettingsVersion.Latest;
		IncludeOrderVersion = EngineIncludeOrderVersion.Latest;
		WindowsPlatform.bStrictPreprocessorConformance = true;
		bPGOProfile = true;
	}
}
  1. run ThirdPerson.exe packaged game, and I got *.pgc file.
  2. I put .pgd/.pgc file in “.Platform/Windows/Build/PGO
  3. Using following Target.cs to rebuild the shiping sln
public class ThirdPerson : TargetRules
{
	public ThirdPerson(TargetInfo Target) : base(Target)
	{
		Type = TargetType.Game;
		// DefaultBuildSettings = BuildSettingsVersion.V5;

		ExtraModuleNames.AddRange( new string[] { "ThirdPerson" } );
		
		DefaultBuildSettings = BuildSettingsVersion.Latest;
		IncludeOrderVersion = EngineIncludeOrderVersion.Latest;
		WindowsPlatform.bStrictPreprocessorConformance = true;
		bPGOOptimize = true;
	}
}
