Description

Anytime yuo switch from a scene to another, from flight to another, or to editor and viceversa the game start to load very slow and it's getting worse after time. One I changed to a flight on mun and the cpu just went to 100% ( 50% dual core ), I terminate the process after 20 minutes of loading, no crash, just task manager kill.

How to reproduce:

launch stuff and change scene go and forth anywhere, from kerbin to mun etc.

Aside from also having the long loading time problem I found another one: loading it background takes multiple times longer than loading in fullscreen.
Loading in fullscreen from the game opening it's fullscreen window to the mainmenu showing up took 44 sec (measured with my phone's stopwatch)
Loading in background (alt tabbed as soon as I could after starting it) managed the game to get to roughly 20% on the loading bar in these 44 sec for a total of 1:13 (left it in fullscreen after checking) to get to the mainmenu.

Gladly my loading times aren't as bad as Brusura's but it's still a bunch slower than all versions before.

Maybe this is related to people getting worse and worse loading times over time?

Same issue on my machine, another set of logs, hopefully helpful.

=====
Issue: Significant performance decrease since upgrading to .21.1

Logs, Saves, Screenshots, DXDIAG:
attached, also available at
http://file2web.com/837KSP_performance_21.1.zip

Version:
KSP Version: STEAM, 21.1.276
Mods / Plugins / Flags: None, 100% stock
Save Games: Previously, lots of unconverted from .20, only one save game created in .21.1. Have since done a completely fresh STEAM install (deleting program folder too), and issues persist.
Controls: Mouse & Keyboard (no joystick)

Details: Since upgrading to .21.1 from .20.2, I have noticed significantly longer loading times, and some in-flight hitches that are affecting gameplay.
I did not gather exact metrics on .20 performance, but the following load time from .21.1 are generally at least 2-3x longer than .20 load times by my estimation.

Load Time Measurements:
Start Screen --> Space Center (SC): 12 seconds
SC --> VAB: 7 seconds
VAB, load Kerbal X [stock]: 6 seconds
VAB, launch button with Kerbal X --> Launch Pad: 33 seconds
VAB, Kerbal X loaded, hit Exit button --> SC: 28 seconds
Munar orbit, ESC menu --> SC: 7 seconds

The SOI Freeze
Flight performance seems about normal, however when transisioning to the Mun's SOI in the KerbalX pod, at timewarp 100X, there was a 5 second "freeze" where all visible activity and control were stopped. When the game resumed, my pod was a lot closer to the Mun than when the SOI change started.
Last night, when approaching the Mun in a different ship at 1000X, the freeze happened for about 10 seconds or so, and by the time it resumed I had overshot my Munar periapsis by a good deal, with serious mission consequences.

On my copy with the scene to scene transitions the "Loading animation" of teh planets seems to spin then freeze, then start again after a pause. Maybe that will help narrow down where that might be.

#4 Updated by TG_bigboss over 10 years ago

Iâm having same issue with scene transitions. Takes over 3 minutes from main menu to launching the Aries 4A. This is using stock steam install
KSP Version: Kerbal Space Program - 0.21.1.276 (WindowsPlayer) Steam

System:
OS: Windows 7 Service Pack 1 (6.1.7601) 64bit
CPU: AMD Phenom(tm) II X6 1090T Processor (6)
RAM: 8192
GPU: NVIDIA GeForce GTX 570 (1233MB)
SM: 30 (Direct3D 9.0c [nvd3dum.dll 9.18.13.2049])

Full KSP log:
http://pastebin.com/GfmLMVL0

Loading times:
Loading your save to the Space Center(SC): 40 Seconds
SC to SPH: 14 Seconds
Load craft file (Aries 4A): 14 Seconds. Longer depending on craft and amount of parts.
Launch: 114 seconds

We have a Thread in the forums with many users having this issue all with posted KSP.log files.

Other notes:* Ksp hangs on the black loading screen with the planet loading icon freezing. Everyone from the Thread posted above have posted about this issue. All their ksp logs both show the error of the missing transforms Group 1-39, which is what we believe, is causing the hang-up before loading the scene.

I think I'm with you all. This thing seems to only be with 0.21.1.

I just wanted to add a new log, with more interesting stuff inside, I was at my orbital station when things were getting slower and I pressed alt+f4 to close right away and it stucked.
