To achieve good and reliable performance, games using DX12 on PC need to manage memory themselves. This presentation goes over Snowdrop's heaps allocation strategies, as well as how its texture streamer is used to manage memory.
Attendees will learn how to use the Windows Performance Analyzer to diagnose VRAM overcommitment issues coming from OS automatic resource demotion, using real examples of performance degradations due to bad memory management in Snowdrop with DX12.
Solutions to address these issues – a resource residency management system and the texture streamer usage of DirectX tiled resources to free large amount of memory while minimizing quality loss – are discussed, as well as what didn't work so well.
Attendees will learn how to better identify and tackle DX12 VRAM overcommitment issues caused by the OS automatically demoting resources, plus some insights on what memory management strategies and systems worked best for Snowdrop.
This presentation is intended for anyone interested in memory management, be it low-level engine & rendering programmers, as well as technical directors looking for ways to keep memory under control on a PC DX12 game.
