New Graphics Card, now docking alignments are all over the place

[cosimas]

KSP: 0.90 Windows 32bit

Mods installed: many

Problem: Hi, this is going to sound a little weird; I'm (still) playing 0.90 and finally got round to getting a decent graphics card (yay).

Unfortunately, something appears to have affected the alignments when docking (boo).

When I tell my ships to point towards the target, the targets are in the wrong place and the ship will point at some seeming random point away from the target docking port.

This happens when using front and side docking ports.

I've come across this problem before when using the Mk2 inline docking ports (before I had the graphics card) - those have a known bug and I try not to use those parts.

This new bug feels almost exactly like that one - as if the game has got confused as to where the target and/or docking ship is.

All three of my dockings since I've got the new card are behaving like this, with a variety of ship designs, using the standard and large ports.

I recon I've made over 250 successful dockings up til now so I like to think I know what I am doing when it comes to docking.

Has anyone else encountered similar behaviour?

Any suggestions? I can list the mods I'm running if that will help but as I said, this problem simply did not occur pre-new graphics card.

Ship line up fine for manuevers etc, it's just docking that has them befuddled

The good news is, I can assure you, it isn't the graphics card.

If I had to guess, I'd say you are controlling from the wrong point. Make sure you control from the mating docking port.

[maceemiller]

Alshain is correct. Right click the port you want to use and select "control from here"

[cosimas]

Thanks for the replies. I can assure you that I always "control from here" on the mating docking port.

Cosimas,

The knee-jerk "you're doing it wrong" is common around here, but there's no reason to believe you suddenly forgot how to dock. Alshain is very likely correct regarding the graphics card having nothing to do with it. While I have no idea what's causing the problem, here's how I would approach finding it:

Copy your KSP folder to somewhere else (desktop for easy access?). Remove all the non-Squad mods from the GameData folder in the copied KSP folder. Launch KSP from that folder, and since your saved game will now almost certainly be broken, create a new sandbox game and test out docking in there. If it works correctly, exit the game and add one of the mods. Test again, and keep adding new mods and testing until the problem comes back. If it doesn't work with all mods removed, then the next step is to try an updated KSP (remember you can keep a copied 0.90 elsewhere) and see if the issue persists there. That's a pain in the backside fix, but from here it looks like your best bet.

Thanks danfarnsy.

I've just started a new game, in the current KSP folder, with all the mods, and launched two simple ships.

They docked as normal, targeted each other fine etc.

With the graphics card making the game run a lot faster, the autopilot "point at target" option is now quite jerky.

I'm now going to go back to my main game, and on the next docking, see if I can pinpoint the issue.

At this stage, I think it may have something to do with switching ships whilst docking.

I think it will be easier to explain if I can capture what happens on video.

I'll be back with more news later.

Also danfarnsy's method is slow. Don't add mods one at a time, list out all your mods and add (or remove) half at a time. So if you've got 100 mods and it's in the 82nd mod, you'd add 50, test, add 25, test, add 12, test and see the error, remove 6, test and notice the error is gone, add 3 and notice the error is back, remove 2 and see the error is still there, and thereby know that it's in the 82nd mod. That takes 6 steps instead of 82 steps of restarting KSP. That saves a LOT of time.

Okay, after several more dockings the problem is with lateral docking ports only. I can't remember them being as fiddly to dock with pre-graphics card, and I certainly didn't have to dock them all "by eye" when using them.

As I noted in the OP, the alignments are wrong each and every time - point at target results in some random misalignment.

Is this just the way they are? It doesn't seem right to me.

Perhaps if you can gives us some screenshots? It would really help to get a visual on this situation.

[cosimas]

Here's a couple of examples.

According to the navball, the docking ship's docking ports are perfectly lined up with the target port. But visually? Nah. The angles are all wrong.

Looks almost exactly like the inline docking port bug I mentioned above.
