The adapter records everything the client draws (state, transforms, lights, fog, textures and buffers) as a command stream, sent in chunks through the shared memory channel, while IMVU's Direct3D renderer still draws the whole view. The renderer process draws it with Diligent, with shaders reproducing IMVU's Direct3D 9 fixed-function setup, over the right half of the 3D view to compare. It skips to the newest frame when it falls behind, and logs its errors and frame times. Co-Authored-By: Claude Opus 5.5 <[email protected]>

// The adapter's engine: what the client draws with. Everything goes to the client's own Direct3D renderer, which
|
|
// still draws the whole 3D view, and is recorded for the renderer process, which draws its part on top (the right
|
|
// half for now, to compare). If the renderer process fails, the client's renderer carries on alone.
