This commit adds damage tracking to the DXGI textures, and only copies the damaged areas to the textures with ID3D11DeviceContext::CopySubresourceRegion. The sleep logic in waitFrame makes it difficult for this to reduce the latency, but removing it shows significant improvements (6-7 ms to ~3 ms) when a tiny portion of the screen is damaged, while showing no difference on full screen damage.
Looking Glass
An extremely low latency KVMFR (KVM FrameRelay) implementation for guests with VGA PCI Passthrough.
