MAKE SURE to use the most updated version at this link: 

bit.ly/gameconfigDR

Tips:
- If you want 5x peds / vehicles don't install other gameconfigs, keep using this one. Find these lines and edit them.

	<AmbientPedsMultiplier_Base value="350"/>
	<AmbientPedsMultiplier value="500"/>

	//OTHER VALUES (leave them unchanged)
	
	<VehicleAmbientDensityMultiplier_Base value="350"/>
	<VehicleAmbientDensityMultiplier value="500"/>

Just lower or make these values higher to fit your liking!

- Remember that gameconfig values are relative based on your PC, set-up, and other mods you need. This gameconfig is one that should be a happy medium with HIGH enough values to handle the mod while not being TOO high for your system 
to handle. Of course try out the other more COMMON fixes to see if that is the cause of your problem. TRY PROGRESSIVELY MAKING THE VALUES OF THE GAMECONFIG HIGHER UNTIL IT WORKS FOR YOU!

    //OTHER VALUES (change them if these don't work)

    <PoolName>CEvent</PoolName>
