That's a game mechanic. We cannot change it.
You need to lower your ships mass or add more thrust.

So my CV does max speed in 1g planet (60 m/s) but in space it can only 66 m/s. This doesn't make any sense to me. Is this a bug or intentional?

It doesn't make sense to me

Max Speed in Space for Capitals is 100 (120 with Booster). If you dont reach that your Engine/Thrustpower is too low for the Mass of your Ship+Cargo. Adding more or higher Class Thrusters will solve the problem if you want to keep the Mass/Blocks ,just dont forget the new Thrusters add Mass too. The problem with that is that you will run into another gap with CPU efficiency ...so you either restrict size/mass of your ship or sacrifice speed/maneuverability or CPU efficiency (which is the worst choice in my opinion). You also have the chance to turn off CPU use at all and are free to go wild on how you build your ship.

ship does max speed in atmosphere but not in space, as i said that doesnt make sense. If you read that latest patch notes they changed it....

And that patch is in the experimental phase and is not in the public branch as yet. So unless you have opted into the experimental patch it will not be affecting the game as yet.

The ship speeds are as much related to the current Computer Tech, as they are to the game rules.

To run real speeds, in a game where you can build anything out of blocks and also can watch the scenery passing by, you would need one of the computers that the government uses to break codes... 8-)

WTF are talking about? Read my OP, my ship does max speed in 1g atmo but not in space.....doesnt make sense.

No one here talking about realistic speeds

Yeah this should be improved on the exp branch. I encourage everyone to check it out there and give feedback to the game devs using a vanilla save.
