# Render cap = capture cap: every present is captured (no 2-of-3 sampling
# beat at 60), and the engine skips render work no viewer ever sees. The
# relay derives its input-settle timing from this value (engine_poll_ms),
# so change both sides together by changing only this line. Measured: the
# CPU saving is ~5% at 8x replay speed (simulation dominates); it grows at
# lower speeds where the render share is larger.
Environment=W3_D3D9_MAX_FPS=40
# Adaptive command quality keeps the 40 FPS source cadence fixed. Q8 is the
# normal profile. The relay can select Q6 or Q1 when measured path capacity
# cannot carry the current command demand, then move back up after two clean
# reports. These flags are encoder capabilities, not client controls.
