(Try 720p) Just a little test to check the speed of Box2D raycasting in a complex scene. The second part of the video shows 10,000 rays, which is so many that drawing a single pixel width line for all of them appears as a solid block of color. The maximum time for a raycast during the test can be seen in the top left: 0.004ms (average time is 0.0029ms).
Measurements taken on Core 2 Duo 3GHz.
