Name	Remarks	Include Path
float CorrectNewResolutionFraction ( float CurrentResolutionFraction, float NewResolutionFraction, float ResolutionFractionScale ) const	Corrects new resolution fraction to ensure it's within bounds, honor AmortizationFactor and FractionQuantization.	DynamicRenderScaling.h
bool DoesResolutionChangeEnough ( float CurrentResolutionFraction, float NewResolutionFraction, bool bCanChangeResolution ) const	Returns whether the ResolutionFraction is changing meaningfully enough.	DynamicRenderScaling.h
float EstimateCostScale ( float ResolutionFraction ) const	Returns how much the GPU cost scales for a given ResolutionFraction.	DynamicRenderScaling.h
float EstimateResolutionFactor ( float TargetMs, float TimingMs ) const	Returns how much the ResolutionFraction should scale for a GPU timing to fit to target.	DynamicRenderScaling.h
float EstimateTimeFactor ( float CurrentResolutionFraction, float NewResolutionFraction ) const	Returns how much the GPU time should scale between two different resolution fraction.	DynamicRenderScaling.h
float GetTargetedMs ( float BudgetMs ) const	Returns the desired GPU cost to be targeted to have head room left to not go over budget.	DynamicRenderScaling.h
bool IsEnabled()	Returns whether the heuristic is enabled or not.	DynamicRenderScaling.h
