When true, cache custom state in PostSolve_Internal (and mark it for current frame + 1) instead of between ProcessInputs_Internal and OnPreSimulate_Internal. This makes clients receive states 1 frame earlier, reducing number of frames needed to resimulate.
Usage
np2.Resim.RecordStatePostSolve [value]
Set via the console (~) or in DefaultEngine.ini / DefaultGame.ini.
