  • RE: Problem seeing/picking up buoys

    @cp65 Yeah, I think what is defined in the rules are minimum dimensions, the actual buoys may be larger, I'd need someone to measure them.

  • RE: Problem seeing/picking up buoys

    @dan-walters The buoys are sized off the dimensions specified in the H1 rulebook and most of the buoys are positioned from GPS coordinates of the actual course layouts. If they seem small and spaced out, that's how they are in real life.

    If you think there may actually be something wrong with how they're displayed in game, maybe attach a screenshot, so I can see what you're seeing?

  • RE: Not working on Mac

    Hey @brotherblonde, I don't really have any good answers for you as I'm not much of a Mac person. I don't own a Mac to actually test the build on. I think there are issues because the software is not digitally signed, I think you have to disable some security stuff in OSX? I'm not really sure. I don't know if anyone has gotten the Mac build to run.

    The Mac build was requested a long time ago and I've been debating whether or not to stop wasting resources building it.

  • RE: Can't set left/ right axis on VRS wheelbase

    @markmoddy it's really hard to figure out unless you have the input debugger open in the unity editor. Have you tried the latest version of the game that I released that has direct input support? That should just work if you enable the prefer direct input toggle. Though there have been some issues (mainly with Logitech wheels).

    See post here:

  • RE: crashes

    @kebos Can you attach the player.log file here?

    It's located in C:\Users\%USERNAME%\AppData\LocalLow\HydroSim\HydroSim.

    Someone else was having crashes in windows 11 and it seemed related to having their wheel plugged in I think.

  • RE: HydroSim v0.8.1.2

    @low12a I will try to have another build up tomorrow that should fix some things. In the mean time, (without the game running) try deleting the inputBindings file in C:\Users\%USERNAME%\AppData\LocalLow\HydroSim\HydroSim and rebind the steering input.

    1. Fixed issues with Fanatec Wheelbase.
    2. When binding with Prefer Direct Input checked, non-Direct Input devices will now be completely disabled to avoid incorrect device getting bound.
    3. Hopefully fixed issues with dedicated server.
    4. Hopefully fixed bug where occasionally boats would start sinking.

    Bundle Updates

    1. Updated water / wind at Tri-Cities.
    2. Fixed an issue with buildings at Madison.

    1. Fixed Force Feedback bugs.
    2. Fixed DirectInput D-pad input bugs.
    3. Fixed bug where super admin couldn't change courses.

    5. Fixed a race condition when initializing Direct Input devices causing things to fail.


    1. Made Direct Input opt-in by allowing user to toggle whether or not to Prefer Direct Input or Raw Input when binding controls. The toggle can be flipped when binding individual controls, in-case something doesn't work with one or the other.

    1. InputSystem now uses custom DirectInput plugin as it should have better hardware support. (See note below)

    DirectInput Notes

    • All Controls will need to be re-mapped in your Control settings before you can drive.
    • The Input System is now fed by a custom Direct Input plugin that I wrote. It's been tested with several devices that didn't work with the old system. Please try this out and post any wheel/pedal/input device issues in the #hydrosim-bug-and-issues channel on discord or as a reply to this post.

  • RE: Can`t get any sound

    @skid2206 The only thing I know of that causes this is if you copied the beta on top of an existing install.

  • RE: using keyboard

    @smity199m You can, but it's really hard to drive with keyboard, especially turning or using the canard, because it's not analog. If you have a game console, you could probably use the gamepad from that.

  • RE: Other boats doing flips and acting erratic

    @low12a I don't know a lot about laptop specs. One thing I usually check when people ask is how old the parts are. From some Google searching, that CPU and GPU were launched in 2013. That's 9 years old.

    To put it in perspective. I didn't even start working on the game until 2016. So...while it's possible those components could perform better than what you have now. I couldn't guarantee that it would be playable. I wouldn't recommend spending money on that.

    If you're going to get a computer with low-end or mid-range components, you're likely better off getting something newer. If you're getting a computer with older components, it's more likely they need to be high-end / top of the line.

    The reality is that as more things are added to the game the higher the minimum specs will keep getting, so you don't really want to be at the floor performance wise. I try to optimize the game as much as possible, but there's only so much I can do.
