Hello. Today I installed Kerbal Space Program 1.2, but I immediately realised something was wrong. The game was really laggy, especially when building in the VAB. I've never had any lag issues in previous versions of KSP. Worth to note is that the same problem occurred while testing out the Pre-Release. General Info OS X El Capitan 10.11.6 Steam Client on Fresh Install No add-ons Kerbal Space Program 1.2.0 2560 x 1440 Resolution, Full Screen Specifications iMac OS X El Capitan 10.11.6 3,4 GHz Intel Core i7 16 GB 1600 MHz DDR3 NVIDIA GeForce GTX 675MX 1024 MB Are you missing something, please let me know. Thanks in advance.

Hello, I can't find a thread about this, or maybe it's just difficult to find. Problem: I'm getting a slight pause in the game that lasts about .5 seconds. This happens anywhere between 6-10 second intervals. I haven't experienced this before 1.2. My ship part counts are not the problem. I'm having the issue occur with part counts that are 34 parts. I'm not running anything besides typically 6 chrome tabs, steam, and really that's it. If you need me to give any more data, let me know specs: Rainmeter (default setting) is telling me my CPU / RAM / SWAP usage is : 38% / 46% / 49% RipjawsX 16gb RAM.

This is getting annoying. I've done literally everything to try and fix it, but still, I am stuck in the laggy, broken OSXplayer of KSP 1.2. By everything, I really mean everything. I have: 1) Verified the game cache many times 2) Opted out of Beta versions of the game 3) Restarted my Mac 4) Uninstalled and reinstalled KSP 5) Uninstalled and reinstalled Steam itself 6) Adjusted graphical settings 7) Asked about this problem everywhere. When the game loads up, on the main menu, it says the build number and in brackets, OSXplayer. I assume this is a prerelease player of 1.2, and its not going away no matter what I do. The performance on it is absolutely garbage, and sometimes the textures in game will completely break while giving me an absolutely nonexistent FPS. Given that 1.2 is supposedly have to have helped performance wise, this is exceptionally infuriating because I have literally NEVER had this much lag and game breaking glitches in KSP before. I'm desperate for a fix, could someone please help out because I am completely stumped.

Hi, I run KSP 1.2 prerelease on Ubuntu 14.04. I've followed every guide I can to increase my FPS, lowered every setting to the lowest it can be, (My computer is a lemon. Don't even ask!) and have it running as smooth as I possibly could get it to be. The problem is planet terrain. Say I have a ship in orbit around Kerbin and I rotate my camera to face space. Everything runs great. But say I rotate to face Kerbin. Everything starts to run slow and laggy. I've lowered my Rendering to Fastest, my Textures to Eight Res, and even created a custom Terrain Preset, "Lowest", where all minDistances = 3. I am wondering if the terrain detail is what is screwing with me though. Whenever I restart KSP, it defaults to "High." Stupid question, but could this mean that KSP is possibly rendering terrain using the High Preset even when it is set to Low or Lowest? I've also noticed that KSP still creates a log file, even when I turn on the "Do not create log" option in the launcher. Other than that, if anyone has any tips to increasing my FPS, mainly while at Kerbin, any help would be appreciated. This same problem occurs in older versions of KSP (so it's not just because of 1.2), and I've already tried redownloading the stock files multiple times. I can attach my settings.cfg file if needed.

Hi there, I run KSP with 8gigs of RAM on a pretty beefy graphics card NVidia GTX590M (for a notebook anyway) on a notebook with an Intel I7 processor. Normally I get around 80 FPS in KSP. Now, I have this space station, around which I have excessive lag. Now I know, that a station with 300+ parts will not give me 80 FPS, but not less than 8... I suspect that there is something fishy going on, but I cannot find the source. I assume it has to do with the following error/warning showing in my log file: [WRN 14:23:03.111] [PartJoint]: None of the provided nodes was valid!

What mod causes Kerbal Inventory System to lag when placing parts?

I am playing a heavymod game. It (the game) has been running very smoothly and I have not had any problems what so ever. The other night I was flying a Command Pod to my space station. I docked just fine, transferred my crew, then undocked and as I fired my rcs retrograde I noticed that the game started running real laggy. 1 in game second would take 3 or 4 real time seconds to pass. I figured my heavymod setup finally caught up to me or the high part count. Wasnt that worried about it. I went ahead and painfully waited for my craft to get out of physics range of the station to see if it would speed back up to normal but it didn't. Again I went ahead with my rentery and landing in Super Happy Fun Time Choppy mode. It was late so I was going to shut game down and troubleshoot the problem the next day and when I was at the title screen I noticed that the rotation of Kerbin was choppy and as the kerbalnauts moved across the screen they were choppy too. I closed down the game and then reloaded it up and the choppyness was still there. I made a brand new sandbox save and loaded it up, built a small rocket and launched it, and it was real choppy as well. After all this narrative my question is this. Even though everything was running completely flawless, could it still be mods that cause everything, even the title screen, to run perma-chop? Out of the blue? I've dealt with high part count, and over-mod issues before. I'm not new to it, but this just feels different and I don't have the knowledge base to begin troubleshooting coding or physic time rates and such. I will start the long process of kicking mods out but I just don't see that being the problem. I haven't added anything new mod wise for a long time, not even any updates for my mods, and as I said before everything was running great, then BAM.... I'm stuck with perma-chop. If anyone has ideas I am all ears, otherwise, if I am lucky enough to find the problem on my own I will let ya'll know. I may try a clean install first with what I call my "Base Mods" first and see what happens. (Base Mods are ones I can't live without like Navyfishes' docking indicator and docking sounds. Mostly just fluff stuff...... er wait why am I rambling I'm sure ya'll don't care and I have work to do! lol)

Hi there. I'm running a fully-patched Steam KSP on Windows 10 x64. I have an issue that has made the game unplayable. In previous versions it happened almost never; now it happens almost always. It happens regardless of how low I set the graphics settings, including render quality, texture quality and resolution. It happens in both the 32-bit and 64-bit builds. I do not see this in other games that use my graphics card, including Diablo 3. It usually happens at random while in the VAB/SPH. The framerate will go from excellent (>60 depending on graphics settings) down to about 1FPS. It will stay like that for about a minute, and then recover for about a minute, etc. It will do so regardless of whether the mouse is moving, what the screen is showing, etc. When it hangs like this, the audio will usually stutter. I read another post on this forum that it could be related to the temperature of the GPU in my laptop. I'm running GPUShark to look at the temperature, and it seems that is not the case. My GPU sits at about 50-60C when idle, and when running the game it ranges between about 60-85C. There is no correlation between when the GPU is hot and when the game hangs; sometimes it's smooth at >80C and sometimes it hangs at <65C. I found that rebooting the laptop and killing most other applications helped, temporarily (for about 30m) but then the problem came back. Any advice would be appreciated.

On a dual-core i7, 8MB RAM, switchable graphics with Intel HD 520 and AMD R7 360, a clean install of KSP 1.1 stutters, where 1.05 is easily playable. On both 32- and 64-bit builds of KSP 1.1, + Loading Systems takes 230 seconds (50s with 1.05) + Main Menu stutters about 1/2 second just before the sprites come into view + Transition screens, black with 'Loading..' in the corner, take 20 seconds (5s with 1.05) + In the scenario "EVA over Kerbin" panning to show the planet stutters for about 5 seconds; panning in camera-view in often stutters about 1 second + Transition from map-view to camera-view takes 1-10 seconds (less than 1s with 1.05) + Esc menu -> Settings -> Accept, with no changes to any settings, pauses for 30 seconds before the Esc menu is responsive + Main Menu -> Quit takes 20 seconds before the KSP window closes This felt like garbage-collection, or file-system timeouts. Things I tried with no noticeable help: reducing graphics quality to minimum, setting the graphics to use AMD only, ensuring the same file-permissions on 1.05 and 1.10 install directories, turning off the send-progress-to-Squad option, pausing Windows Defender, setting the KSP option to use LEGACY_SHADER_TERRAIN, ... Any suggestions? Logs and DxDiag are here.

Hi guys, With 1.1 came performance increases. The title says it all, I was just wondering. Which one of those will get you the best mix of graphics and performance. For example, I don't want 144p graphics but 120 fps, but at the same time, 1440 p graphics with 12 fps won't work either. Discuss below!

Ok, so I have been using opengl windowed KSP for about month now, with all of my graphics settings down. My headphones are broken, and my laptop speakers are too quiet. so, on my first attempt at an Eve mission, I can't tell when I am entering the atmo. This was a major problem. so, I start fiddling with my settings, trying to get the aero affects to work, and it sys I have to restart for my changes to take affect. I accidentally hit fullscreen at some point, and now KSP crashes on startup. I removed the opengl line so It isn't causing problems, and I m at a loss. Oh, and when it isn't mid-crash, it just gives me a black screen with the KSP pointer. Halp. Also, can someone point me in the right direction for those aero affects?

So a few days ago, KSP started lagging more than usual. For example, I used to be able to fly lag free up to around 300 parts, but now it lags at 200, quite badly. I have NOT changed any settings on my game OR computer, everything is as it was before, yet the performance is worse. A strange thing is that the lag seems to be slightly less when the vessel is on the surface. Any ideas?

Hello, I just am asking for some help. I experience a 1 to 2 second lag every 1-5 seconds. The scenery setting is already set for low. I also have some mods, including dynamic texture loader. I used to have Active texture management, but I hated that all of the icons and flags on the contract got pixilated. I don't know if it is my computer (I know that it is not the best one) or if it's the settings or the numbers of mods that I have. All advice is appreciated. Here is my mod list. Thanks .

Version: 1.0.5 non-Steam 32bit OS: Windows 10 64 bit Hi everyone, I had KSP for a long time and I just started using it again, on a gaming PC. I started to build a multi-purpose station that consisted of more than 400 parts. The game performance was horrible. I was getting 1fps per second according to the performance menu. It was incredibly painful having 1fps. It made docking pretty much impossible. I don't know about you, but 1fps makes me dizzy when watching the screen. Anyways, I looked at task manager and KSP was only using 30% of my CPU and 1.7GB RAM! Overall, only 35% of CPU was being used on my computer and 69% RAM. I just don't get it. Why is it lagging so much? It is hardly utilizing my new gaming PC's resource at all. I have other simulation softwares and they work fine. For example, Microsoft Flight Simulator X and Prepar3D run fine for me. For any of you who don't know, those 2 simulation software are the ultimate PC killer. My computer can run it around 20fps. However with KSP I only get 1fps with 65% CPU and 31% RAM unused. This must mean KSP is hardly using my PC's resources well at all. What is wrong here? I really want to build interstellar ships and big space stations but KSP is really limiting my ceativity. The computer bascially has no problems coping at all. However, KSP starts to lag after 400+ parts, and this is just getting annoying- it takes the fun away and it wastes a lot of time. Any help will be appreciated.

Hello everyone. Need some help with this messy bug. At first - KSP build build id = 01028 found this bug yesterday, after installed huge amount of mods. Today i deleted all the mods via CKAN. then deleted game via steam deleted folder of the game in stamapps\common dowloaded game via steam. And the bug is still there. What a bug? So, i'll lry to explain when in VAB i create rocket. And after i created rocket i manage some details to activate on different stages and\or create some noew tsges. Here comes the bug! When i point mouse cursor on right line of stages - FPS drops to ~0.1-1 but mouse cursor works fine, and when i point cursor on some other thing - FPS returns to normal state. attaching output log and dxdiag. https://www.dropbox.com/s/izpk1h4wnmsuros/DxDiag.txt?dl=0 https://www.dropbox.com/s/ektsx6thb0tadrb/output_log.txt?dl=0
