Screen capture and Overlays for Direct. D 9, 1. 0 and 1. 1So its been almost a year and I have finally got around to finishing a new version of my screen capture project that supports Direct. D 9, 1. 0, and 1. This solution still uses Slim. DX for the Direct.

DX June 2. 01. 0 SDK or Runtime, and it is useful to have the Direct. X SDK handy to try screenshots on their samples. The download already includes the Easy. Hook binaries, but if you want to download them yourself you can find them at Code. Plex here. C only Implementation. Previously I had a C helper DLL to get the VTable addresses.

Present method to capture in D3. D 1. 0 1. 1. The capture method used in Direct. D 1. 0 and 1. 1 is also more thread safe allowing us to extract data from the resulting texture on a background thread. This reduces the impact to the frame rate. We are also able to copy only the region of the backbuffer that we are actually interested in making the capture of smaller regions quicker as less data needs to be copied to system memory. This also will make capturing a sequence of frames for use in video production much easier. Note I believe that D3. D9. Ex Vista shared surfaces e. DWM also uses the DXGI Present but havent looked into this in greater detail as the End. Scene hook in Direct. D 9 achieves what we are after also.
