Here’s a snippet of how I apply my game settings that you might find useful:

void APWNGameMode::ApplyGameplaySettings()
{
	// Set FOV
	PlayerController->PlayerCameraManager->SetFOV(GameplaySettings->GetFOV());

	// Vsync
	if (GEngine)
	{
		GEngine->bSmoothFrameRate = (GameplaySettings->GetUseVSync() ? 1 : 0);
		
		//Changed in 4.2	
		GEngine->SmoothedFrameRateRange = FFloatRange(GameplaySettings->GetVSyncMinFPS(), GameplaySettings->GetVSyncMaxFPS());		
	}	

	// Test detail settings - Should move to gameplay settings
	if (GEngine)
	{
		// Set quality
		Scalability::FQualityLevels q;
		q.AntiAliasingQuality = GameplaySettings->GetAntiAliasingQuality();
		q.ViewDistanceQuality = GameplaySettings->GetViewDistanceQuality();
		q.EffectsQuality = GameplaySettings->GetEffectsQuality();
		q.PostProcessQuality = GameplaySettings->GetPostProcessQuality();
		q.ResolutionQuality = GameplaySettings->GetResolutionQuality();
		q.ShadowQuality = GameplaySettings->GetShadowQuality();
		q.TextureQuality = GameplaySettings->GetTextureQuality();
		Scalability::SetQualityLevels(q);
	}	
}

My GameplaySettings class is just a container with some config readers, getters and setters, so e.g.

GameplaySettings->GetAntiAliasingQuality()

Just returns a value between 0 and 4 depending on what was specified in my custom config file.

Thank you very much. it worked.

but I still do not know how to get the screen size and Framerate max

Max frame rate can only be set via Vertical Sync (bSmoothFrameRate).

Screen size you can set via a console command, e.g.

if (GEngine)
{
    GEngine->Exec(GetWorld(), TEXT("r.SetRes 1920x1080"));    
}

  • I meant frame rate will only be capped when bSmoothFrameRate is true. It will then use the max value specified in SmoothedFrameRateRange.
