This mod allows you to go 300 000 000M/s in the game with both small and large ships. Note: The actual speed you can reach varies per machine, some people reported they weren't able to go past 1,000,000m/s but others reported speeds as high as 1,600,000m/s.

No, you can't reach that speed on any normal machine, but you can go a lot faster than you think; just look at the screenshots, I'm flying at 420KM/s. Rendered on an i5 4570S + HD6970.

1000M/s is very doable, no issues.

8 000M/s asteroids fly at you at about the same pace as the 'stars' screensaver in win 95.

at 25 000M/s the engine starts to have issues keeping up and you'll get UPS drops.

at 30 000M/s+ asteroids will mostly be spawning behind you, but hiccups aside you can fly pretty smoothly.

at 400 000M/s FPS is alright, but UPS completely freezes, making the game stall, probably as I'm flying through asteroids before they're even spawned.

For comparison: 1000M/s / 1KM/s = Mach 2.93 = 3600KM/h 400KM/s = Mach 1175 = 1440 000KM/h = 0.0013C (speed of light)

Note that colissions will start behaving strangely above certain speeds, e.g you will fly through things without or minimal damage. This is due to the fact that the engine only updates at 60 "UPS" or (physics) Updates Per Second. That means that if a colission takes shorter than 1/60th of a second (~16,667ms), it won't be registered or things will act strangely. That is, in ideal conditions, as usually on more full servers or even singleplayer your UPS will be lower than 60. Additionally Havok tries to compensate for aforementioned issues, so the issue is more complex than just that simple math, but the root of the problem stays the same. If you press CTRL+H you get a little graph that shows a bunch of things among "UPS", that's the physics framerate. More detailed info can be found in CTRL+F11.

On the bright side, after you reach about 30KM/s, most ships will pass through asteroids without damage, so it's a little bit like flying at warp speed :)
