I don't know much about AMD and cross fire, but I have gtx 670 in SLI. At default, KSP only uses the primary card. I can force SLI in nspecter (3rd party graphic card setting program). KSP then does in fact use both cards. I get a bit higher FPS but a lot more stuttering. So I leave it on just using one card.

Looks like I solved the problem, updated my original post.

Yea, regarding the tech nodes, that message pops up in the alt+f2 window every time i enter VAB and I've never crashed there, so most likely that's not it. Buttttt....I may have found the problem. I've updated my BIOS as I found some source that said my motherboard wasn't setting the speed of my PCIe slots correctly with the older BIOS version. Would make sense since crashing only occurred at 100% usage. Anyways, I'm still testing as of now. I'll report back in case someone else is having similar issues. Appreciate the help so far.

I didn't have too much time to play around with it last night. But All the sub folders in the KSP folder were checked boxed as read only. I would uncheck them (including sub folders/files) and have the loading screen going through the files. Once it's done, I'd go back into properties on any of the folders and they were still marked read only. I'll look into it some more when I get home tonight. Are all of your subfolders in KSP unchecked for read only? Also, any idea what the "No tech node" error is or means? And I'll look into that dll some more. Thanks again for at least giving me some direction to go in. I'm not new to trouble shooting computer problems, but this one is getting the better of me. More testing last night...Even if I drop all my graphic settings to low but keep my 2560x1440 resolution, I still get 99% GPU usage or close to it when looking at or near the ground with FPS not going above 60ish looking at KSC, and will crash. Even in window mode 1080 resolution is between 95-99% looking at the ground. Once I'm in space usage drops to 20-40% and fps can be >120. Doesn't seem right. Ran a benchmark with Shogun 2 at max settings just in case, which stressed both videos cards to 99-100%. Got an average of 130fps over a few minutes with no crashing.

That's interesting. When I click properties for Common and Kerbal, it's marked as read only. When I unclick it it shows the files working and ends. But if i go back to properties, it still shows it as Read-Only. Any ideas?

Darren, I guess that's not too far off from what I get. These are my recent crash logs... https://www.dropbox.com/sh/gwwxz3ks9kq9xx7/AABqvlk8jD2eiGmDsOPu2BLLa?dl=0 Vexx, what weird messages are you talking about? Crashes always seem to happen with my GPU usage gets pegged at 100%, which for some reason doesn't take much. Again, this is the only game it happens in. Any theories or ideas are much appreciated.

Did rolling back the drivers help? Which drivers? What video card do you have? Your problem seems very similar to mine. Do you monitor your video card usage % when the crashes happens? This is the link to my problem.. http://forum.kerbalspaceprogram.com/threads/106177-KSP-GPU-crash-Please-post-GPU-Usage

This is a link to my previous post which I included my crash logs. I'm definitely not running out of memory. http://forum.kerbalspaceprogram.com/threads/103186-Seemingly-Random-Crashes Can you pan around your camera when you're taking off to make you're GPU reach 100% sustained at all? All my launches, even small craft, do. Anything with over 30 to 40 parts will crash unless I have my camera tilted up.

............................................................................................................................................................ SOLVED: Just to update. I seem to have solved the issue. I updated my bios version on my motherboard and haven't had a crash yet. Just in case anyone is having a similar issue, I have the ASRock z77 Extreme4 motherboard (this might affect other boards, not sure). My old version of bios would only let me select 'Auto' or 'Gen 1' speed under the PCIe Speed tab in bios. As soon as I updated, the options of 'Gen 2' and 'Gen 3' came up. Apparently early versions of the bios firmware did not use the graphics card at full speed. Anyways, hope this helps someone, it took me a while to figure out. ............................................................................................................................................................ Hi, First I ask if anyone with a similar rig could please post what GPU usage % they get when they first load their game into the kerbal space center without moving their camera. This would be with max settings. Read on for my issue... I've been trying to track down the source of my seemingly random crashes of KSP. I've spent the last couple of weeks taking apart my computer, moving files, running tests, etc. My computer specs: i5, stable overclock to 4.4Ghz 8 gig memory GTX 670 SLi 27inch 1440p monitor I've narrowed my crash to the fact that my one GPU (looks like KSP doesn't use SLI) gets used up to 99% when simply loading a new game which shows the kerbal space center. My game will crash within seconds to minutes unless I pan my camera to the side where my GPU usage % drops down to lower, be it 80%, or 50% or lower. This doesn't just happen around KSC. When landing on other planets, if GPU % goes to 99%, game will crash again in a few seconds to a minute unless I pan the camera. I've also had to limit my FPS to 60 instead of 96 (my monitor refresh) as the lower FPS helps bring down the GPU usage %. This can not be right... I have no stability problems with my rig. I've returned all my overclocks to normal and get the same result. I've run memory tests, CPU torture tests, GPU torture tests, etc. No crashes and no heat problems. I've removed my second GPU card to test with one, I've switched them to see if its the card it self. I've tried different drivers. I've tried different resolution monitors. KSP is the only game I have an issue with. Asking first for someone to provide what GPU usage % they get on load a game, and for advice on where to go to next as I am out of ideas...

Read through the links but doesn't seem to apply to me. Is there anyway I could be running out of memory? It would seem strange as I have a powerful computer, 64 bit OS, and this happens on completely stock game. Anyone have any other suggestions or ideas? Again, crashes seem random and I can not reproduce them. Sometimes happens after 1 minute in building mode, sometimes after 10 minutes of flying around. Different crafts, etc etc.

Here is another log. I flew the default VTOL for about 5 minutes. Finally ran out of fuel and had a big crash(actual aircraft crash). No crashes. Go to click to return to space center...crash. https://www.dropbox.com/s/tqc84kcko15rpdy/output_log3.txt?dl=0

KSP Version - 32bit KSP, Steam, happened in both .25 and the recent 0.90. Has happened with fresh installs, no mods. Game seems to freeze. When I alt-tab out, the error message is shown. When I hit OK game exits and the error logs are generated. Its happened at what seems like random times. Sometimes after a few minutes after take off, sometimes right at take off, sometimes I can make it the Mun and it'll crash. Also crashes have happened when I try to revert back to launch or build. The crashes are not consistent. I purchased through steam, crashes are frequent and I rarely can get through a mission.
