Welcome back,soldier.

1. The light pools around the blast and fades with distance.
2. The far walls and the ceiling stay in shadow.
3. Each surface keeps its own colour instead of turning yellow.

3. Your weapon catches the light.

1. Soft shade under the Warthog, where its wheels meet the sand.
2. Its wheel wells, seats and gun get depth in their creases.
3. The sand, the rocks and the base keep the level's own lighting.

1. The ground and the cliffs at the sides keep their shape instead of smearing outward.
2. Upright edges, like the cliff's, stay straight.
3. You see just as far to the sides; the middle is drawn larger.

A slowed-down race from one click to the shot on screen: GOAT H1 120 Tick shows the shot 5.9 milliseconds after the click, the original 47.7 milliseconds after it. GOAT H1 fired 8 times sooner: 42 milliseconds you would otherwise be waiting. Faint marks behind each lane are its steps: every 33.3 milliseconds for the original, every 8.3 for GOAT H1.

Pause Try it at real speed Timed from our measurements

Measured with the game's own log (debug.latency_log): pressing fire to the frame handed to the screen, median of 21 presses (50 for the original), on a Mac, in a local game with bots. Your display adds its own few milliseconds to both. The original's timing is recreated in GOAT H1 with its improvements switched off: 30 ticks, one frame a tick, no frames between ticks, the view drawn from the last tick. Each stage is its own median. This is a local game: on the Xbox's system link, which ran in lockstep, your own moves also waited a round trip to the other machines.
