Consider scaling down expensive graphics in remote e.g., Animations Detect if the session is remote: Managed: System.Windows.Forms.SystemInformation.TerminalServerS ession Win32: GetSystemMetrics(SM_REMOTESESSION) Consider session transitions Leverage RDP Compression GP’s 30-40% bandwidth savings Important to test your app remotely!

Use Direct2D – has efficient command remoting Direct3D Apps: Use DX10.1 and DXGI 1.1 (DirectX Graphics Infrastructure) CreateDXGIFactory1(…); pFactory->EnumAdapters1(i, &pAdapter) pAdapter->GetDesc1(&Desc); BOOL IsRemote = Desc.Flags & DXGI_ADAPTER_FLAG_REMOTE; Use the new IsCurrent() API to handle session transitions and discover new adapters Tip: Local optimizations are magnified remotely!
