Hi, for a complete scene render which involves rendering some render targets, I was wondering which is the correct way of calling some functions... I'm thinking of two possible ways: way 1: For every Frame - Check Cooperative level - BeginScene - SetRenderTarget - Render Something - SetRenderTarget - Render Something - SetRenderTarget - Render Something - EndScene way 2: - Check Cooperative level - BeginScene - SetRenderTarget - Render Something - EndScene - BeginScene - SetRenderTarget - Render Something - EndScene - BeginScene - SetRenderTarget - Render Something - EndScene so, which is the fastest/safest way?

You should only be calling BeginScene() / EndScene() once per frame. Specifically, there should be at most one BeginScene() / EndScene() pair between any successive calls to Present(). To maintain maximum parallelism, it is advantageous to call EndScene() as far ahead of calling Present() as possible.
