The point the camera looks at is its position plus an offset (setCameraFocus,
at each tick), so between ticks it now moves with the eased position: panning
moves the target the position eases to, and was still at 30 per second.
Between ticks, an animation is moved on at the rate it moved at the last step
(per tick: the client steps several ticks at once when it falls behind), not
only when it moved exactly a frame: animations played at other speeds were
posed at the tick, between smooth ones.
The engine's stats also log the longest time between frames.

The renderer process now takes each view's chunks on a thread of its own as
they come, and draws the newest frame on its main thread: the client no longer
waits for the previous frame to be drawn (on a VM, 22 of a frame's 25 ms).
The adapter records the client's steps (SceneViewer::step, by replacing its
entry in the exported IFrameListener vtable, after checking it), and the frame
pacer doesn't ask for a frame that wouldn't end before the next step is due: a
late step made the client catch up two at once, which showed as hitches. While
the renderer process covers the view, the client's renderer doesn't begin or
present frames, which could wait for the display.
The engine's stats now include the time in the client renderer's methods.

The pacer counted only its own frames, so the client's 30 came on top (60 gave
about 80), and it added no frames at all when the rate was out of reach. It now
asks for a window's next frame once the interval since its last frame began has
passed, and the client has had a third of a frame's time idle: all frames
within the rate, and as many as the client can draw when it can't reach it.
The engine's stats also break a frame's time down: sending to the renderer
process, bytes sent, buffer updates.

The frame pacer repaints the client's 3D windows at the user's frame rate
(HKCU\Software\T5DE\Graphics\FrameRate: 30, the default, adds nothing; 60, 120,
240, 360; 0 uncapped), so the client draws frames between its 30-per-second
steps. Only when affordable: a window is asked once its last frame is drawn,
and only if its frames take under three quarters of the interval; uncapped,
the client is left idle a third of a frame between frames. The engine's stats
now log frames per second.
The extra frames show the same scene for now.

While the renderer process runs, the adapter makes the client's render targets
itself and the renderer process draws frames into them: texture targets are
drawn with like any texture, and a pixmap target's frame is read back through
the channel into its Pixmap (protocol version 4: BeginFrame names its target,
CreateRenderTarget, Channel::readSize and the -read event). Frames into render
targets are drawn even while the window is hidden.
The client uses pixmap targets for snapshots (outfit pictures, photos), checked
to look right. The render target interfaces are declared from IMVU's vtables.

The full view is now the default. While the renderer process covers the whole
view (Channel::covering, set after each frame it presents), the adapter skips
the client's renderer's clears and draws, decided per frame; the client's
renderer still gets state and resources, and draws again as soon as the
renderer process stops covering the view.
The client's window no longer gets WS_CLIPCHILDREN: the client draws when its
window gets WM_PAINT, which a window entirely covered by clipped children never
gets (it fell to about one frame a second). The flip model swap chain shows
above the client's drawing anyway.

IMVU's projections give depth from -1 to 1; its Direct3D renderer maps it to 0 to 1, and now so does ours. Without that, the nearer half of the depth range was clipped, the whole 2D overlay (name tags, the frame rate, the room's title) with it. The adapter also draws drawTrianglesFromMemory without indices, and sums up what the client draws in its log.

Particles: Direct3D 9's size limit evidently isn't the documented 64 pixels; unclamped (up to 2048) they match the client's renderer. A compare view shows the left half's scene over the right half, both renderers side by side; %TEMP%\t5de-renderer-view.txt switches views and %TEMP%\t5de-renderer-shaders\fixed_function.hlsl replaces the shaders while the client runs. The renderer process runs from a copy, so the program can be replaced meanwhile. The adapter recognizes only the textures and buffers it made (others reach the client renderer unchanged) and logs the others and render targets.

Particles (point sprites) are drawn as instanced camera-facing squares sized like Direct3D 9's. Fog is by depth buffer value, as Direct3D 9 does with IMVU's projections. At most one frame is queued for display, frames carry the adapter's timestamp so the renderer process logs the delay to presenting, and the log's lines from several processes no longer mix.

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.
