- Updated StressTest_MetasoundOutputs to optionally use the new native delegates. - In local testing the native delegates were ~40% faster on average than dynamic delegates, when measuring FMetasoundGeneratorHandle::UpdateOutputWatchers. #rb charlie.huguenard phil.popp #tests EngineTest - PIE, Standalone #virtualized [CL 29067112 by robert rouhani in ue5-main branch]
