  1. KSP has performance problems running on OpenGL on Linux too. There are other games on Linux, some using Unity, that don't have issues like KSP has. In particular the garbage-collection stutter has everything to do with Unity's outdated version of Mono, and KSP's code running on top of that, and little if anything to do with DirectX. I've seen nothing to make me think any other general-purpose engine would be better than Unity for KSP2. I don't know any games in other engines that come close to KSP's scale and range of speeds. I've long advocated a custom or special-purpose engine, perhaps Space Engine, but Star Theory have decided not to change. For what it's worth, Simple Rockets 2 also uses Unity.
  2. If I remember rightly 1.0.x was awful, abysmal performance. 1.1 improved that a lot. 1.7.1 gave me so much painful VAB lag that I can't yet call it my favourite. But then Breaking Ground is awesome, so...
  3. So far. Biggest improvement: Visuals. Biggest let-down: Appears to still be discrete parts, not fully-procedural. Biggest concern: I've never heard of the developers.
  4. If it already has Windows 10 on it, MIcrosoft now uses "digital entitlement", recording details of your hardware (including the unique MAC address for the ethernet and wifi adapters). You can do a fresh install of Windows 10 and it will connect to MS's activation servers which will recognize that yes it's the same laptop, so you don't need to enter a product key. There should be a key sticker on the laptop anyway in case you do need to put it in. And you can actually download Windows 10 freely from Microsoft. They're happy now for us to make our own install discs / usb sticks. The "Media Creation Tool" is a bit lousy but it does work. Note that if you want to use a DVD, the most recent versions of Windows 10 don't fit on a regular DVD, you'll need a dual-layer. Worked for me putting an SSD in our laptop a couple of weeks ago anyway. If it currently has Windows 7, I've found Windows 10 will usually activate using a Windows 7 key, even though the "free upgrade" has officially ended. If there's no key sticker on the computer, you can use a program to get the product key before you take the old drive out. EDIT PS: And yes, it's made a huge difference. I'm now able to actually turn on the laptop and use it, whereas with the previous awful hard drive I just spent so much time waiting. I opted for a Crucial MX500 512 GB (the same drive I have in my desktop), and also added RAM to a total of 12 GB. Probably overkill on both counts (the drive being one of the best-in-class) but as the saying goes, buy cheap buy twice.
  5. Known bug with Kopernicus. Disabling both terrain scatter and Breaking Ground surface features may mitigate it. Otherwise rollback to KSP 1.7.1 until Kopernicus is updated. EDIT: I didn't read. But double-check that Kopernicus isn't still in GameData by mistake. Even if no planet mods are present, Kopernicus alone causes the issue.
  6. Junos can make stuff go like a bat out of hell.
  7. Research, practice, and experiment. And above all else be patient and methodical. I've been known to spend multiple play sessions just getting a single gravity assist right. If you're trying to get gravity assists off a moon, for example using Tylo or Laythe to capture at Jool, then an important technique is a mid-course correction that balances pro/retrograde and radial burns. This allows you to keep your *trajectory* into the Jool system approximately the same, but change your arrival *time*. That's how you meet the target moon at the right time and place. As mentioned it's not everyone's cup of tea. I for one take great pride in my gravity assists which is why I'm willing to put in the effort.
  8. VAB lag. It made building my Saturn V torturous rather than enjoyable. Trying to lock a gimbal only to find the lag means I've ripped a chunk off the rocket (and undo will have me w a i t i n g ages ), trying to rotate the camera and having it jerk and judder. It completely killed the fun. That's why I'm staying off KSP for a while. Sure, the rocket was big (about 700 parts), but I and others have built bigger. Flight lag I can tolerate, if only because after the launch to orbit usually most of the parts are going away, but VAB lag is different.
  9. Thunderpants. Adds a new resource, Fartpower, and high-performance engines that run on it. The "Bean" is a basic model, then there's the more powerful "Sprout" and "Egg", the vacuum-optimised "SBD", the 5 metre "Vindaloo" engine, and "Cabbage" high-thrust RCS quads. Fartpower cannot be loaded onto a rocket in the editor. Rather, Kerbals with the FlatS trait convert liquid fuel into Fartpower at a certain rate. In Career mode these Kerbals can only be obtained by doing special rescue contracts.
  10. Do you have any mods that add items or resources to Kerbals. For example any life support mod, or KIS/KAS? They can make the Kerbals heavier which will produce the results you describe, especially if they have a bug and give the Kerbal excessive resources.
  11. Radiation makes superheroes right?
  12. Except we can't. The new fuel tank version, when emptied, is significantly more massive than the deprecated structural-only version. This affects use cases where you're not using much LFO tankage on the relevant stage, for example nuclear ships. You can still find deprecated parts through the advanced part filters, for example show all 3.75m parts and the structural adapter is there. But it's quite possible Squad will remove deprecated parts in future.
  13. Yeah, the simple solution has always been to put a probe core in the correct orientation. (A docking port works too). Now that we have robotics, a refinement is to put a probe core on a hinge so you can dynamically set the control direction in flight. People have been using this to make rocket autopilots - by rotating the probe core, SAS will tilt the whole rocket in order to keep the probe pointing straight up.
  14. How KSP has moved on. Anywhere it's nowhere near my biggest stuff in stock, but I set my RSS record as part of my Saturn V recreation: 186 tonnes in LEO. LEO established by cantab314, on Flickr Mass in orbit by cantab314, on Flickr Of course this invokes the old discussion of what counts as payload. You can argue the 186 tonne mass is "payload to LEO" in the context of a Moon mission, but that doesn't mean it can put 186t of whatever you like to LEO. I think a fairer payload figure in a case like this would be to count the upper stage remaining fuel, but not its structure, on the grounds that if you short-fuelled the stage you could add that much payload. In my Saturn V's case, subtracting the 39 tonne dry mass of the stage gives a "true" payload of 147 tonnes to LEO. But then it could probably actually lift more. It's hard to know exactly without testing because adding more payload but not removing fuel will affect TWR and delta-V across all stages. For a rocket that already has a low TWR that may be an issue, especially in stock with high payload fractions.
