Member Function Documentation

GetResolutionFractionsApproximation()

virtual DynamicRenderScaling::TMap< float > FDefaultDynamicResolutionState::GetResolutionFractionsApproximation ( ) const

inlineoverridevirtual

Returns a non thread safe aproximation of the current resolution fraction applied on render thread, mostly used for stats and analytic.

Implements IDynamicResolutionState.

GetResolutionFractionsUpperBound()

virtual DynamicRenderScaling::TMap< float > FDefaultDynamicResolutionState::GetResolutionFractionsUpperBound ( ) const

inlineoverridevirtual

Returns the max resolution resolution fraction.

Implements IDynamicResolutionState.

GetResolutionFractionsUpperBoundBudgetValue()

virtual DynamicRenderScaling::TMap< float > FDefaultDynamicResolutionState::GetResolutionFractionsUpperBoundBudgetValue ( ) const

inlineoverridevirtual

Returns the max resolution resolution fraction as specified in the budget (this can differ from the upper bound if the upper bound is dynamic)

Reimplemented from IDynamicResolutionState.

IsEnabled()

virtual bool FDefaultDynamicResolutionState::IsEnabled ( ) const

inlineoverridevirtual

Returns whether dynamic resolution is enabled for GEngine to know the EDynamicResolutionStatus.

Implements IDynamicResolutionState.

IsSupported()

virtual bool FDefaultDynamicResolutionState::IsSupported ( ) const

inlineoverridevirtual

Returns whether dynamic resolution is supported on this platform.

Using dynamic resolution on unsupported platforms is extremely dangerous for gameplay experience, since it may have a bug dropping resolution or frame rate more than it should.

Implements IDynamicResolutionState.

ProcessEvent()

virtual void FDefaultDynamicResolutionState::ProcessEvent ( EDynamicResolutionStateEvent  Event )

inlineoverridevirtual

Process dynamic resolution events. UEngine::EmitDynamicResolutionEvent() guareentee to have all events being ordered.

Implements IDynamicResolutionState.

ResetHistory()

virtual void FDefaultDynamicResolutionState::ResetHistory ( )

inlineoverridevirtual

Reset dynamic resolution's history.

Implements IDynamicResolutionState.

SetEnabled()

virtual void FDefaultDynamicResolutionState::SetEnabled ( bool  bEnable )

inlineoverridevirtual

Enables/Disables dynamic resolution. This is only called by GEngine automatically.

Implements IDynamicResolutionState.

SetTemporalUpscaler()

virtual void FDefaultDynamicResolutionState::SetTemporalUpscaler ( const UE::Renderer::Private::ITemporalUpscaler *  InTemporalUpscaler )

inlinevirtual

Apply the minimum/maximum resolution fraction for a third-party temporal upscaler.

Implements IDynamicResolutionState.

SetupMainViewFamily()

virtual void FDefaultDynamicResolutionState::SetupMainViewFamily ( class FSceneViewFamily &  ViewFamily )

inlineoverridevirtual

Setup a screen percentage driver for a given view family.

Implements IDynamicResolutionState.
