1.0.5.1028 Slowing down

[Jaeleth]

Hi.

I installed v1.0.5.0 as soon as it was released, but since the few mods I was using were not updated then, I tested it but waited to migrate my career game.

I let time go bye and, finally, migrated my career game from 1.0.4 to 1.0.5 a couple of days ago.

But... A strange thing happened. The game runs incredibly slower. Not only that but every x frames (say, every 3 seconds, real time, to 10 seconds, sometimes) the screen freezes for half a second, and then resumes...

I removed all mods to see if it was an incompatibility problem but no... Problem remains.

I noticed that if I start a new game, build a small jet aircraft and fly it, for instance, this problem does not appears or is not noticeable.

If I remove almost all ships from my career saved game and fly an SSTO (more complex ship), I start noticing the slowdown

If I use my saved game in full, all ships, all missions and MechJeb (I have to have MechJeb installed in order for most of my ships to load), the problema assumes drastic proportions. I am pretty sure that it is not MJ fault, since even without it, the problema is noticeable. NOTE: There are no ships within the 2.3Km radius of the test vessel, just around Kerbol system and far away, as usual.

Using 1.0.4... no problems at all.

 

Any clues?

What mods did you have installed in 1.0.4?

[Jaeleth]

Mechjeb II, AGX (action groups inflight edit), Hyperedit, Kerbal alarm clock, ship manifest. From all of these only mechjeb has implications in ships components, however, the problem is not in 1.0.4, but in 1.0.5, and in 1.0.5 I removed all mods to test.

This is, apparently, a common problem. Well, it happens on my machine... but my friend who runs linux doesn't have that problem.

Go figure.

Ummm, I mean, I don't think its the mods at all, its just the game, or your video card... no easy answer except to hope 1.1 fixes it.

And i have it mostly on linux. I have it on windows too, but barely noticable. Appearently its a combination of inefficent unity GC on some systems and the game not being able to handle that correctly. Theres a thread about that somewhere...

Yep.... the fix is in the hands of the Gods for now...

Squad, we bow our prostrates to you, please fix this problem.

Well... I guess I'll keep playing in 1.0.4 for the time being then... No heat model or flight model tweaks or a few extra gadgets, albeit cool, are worth the absolute stall the software gets into 1.0.5...  In my conditions.

Does 1.0.5 checks for anything else than the 2.3km sphere around currently selected vessel? Anything else but what 1.0.4 did already. Because I have hundreds of spacecraft and debris floating around Kerbol system and if squad changed the way that objects, outside of that shpere, are treated, that might be the cause.

Immo the game should not be upgraded to a point where only super machines will run it, at least not without a players option to downgrade it by tweaking settings (and, in a game like this, I am not exacly referring to graphics settings, but to the calculation of the applied models, where applicable) or else this will put off thousands of people who don't have the money to buy a super machine.

But I find it strange being a graphics card problem, since, in a strict graphics point of view, there is almost no difference for taking off an averagely complex SSTO or a small jet off KSC. Since the majority of the graphics being rendered at the time are KSC buildings, the difference between the SSTO and small jet, in terms of total polygons to be rendered on scene should be less than 1%. And I don't have problems with a small jet, on a new game, and a lot of problems with an SSTO, on my migrated career game...

Unless you have a very low-spec graphics card, i don´t think thats the problem. KSP does all its physics-based calculations on the CPU. GC (Garbage Collection, look here https://en.wikipedia.org/wiki/Garbage_collection_(computer_science)), which is used by Unity and causes the game to freeze periodicly on some systems, is also entirely CPU based. Upgrading the CPU might help, but its not guaranteed. I have a pretty good Intel i7, and i have the same problem.

AH, ok, mistook GC for graphics card ;). Now it makes sense

That´s why, in aviation, ATC never uses registration abbreviations when there might generate confusion  eheh
