DirectX12 View Instancing and Vulkan Multiview
- Normally the draw calls will be sent from the CPU to the GPU multiple times which can become a bottleneck for scenes with a lot of objects or drawcalls. Xᵉ-LP introduces support for hardware that enables replicating geometry for multiple views in a single pass. By converting multiple passes or instances where the geometry is processed the same way to a single pass avoid redundant CPU and GPU work.
- Xᵉ-LP supports Tier 2 level of VI on D3D12 and works in conjunction with VRS to enable further performance gains.
