Incredibly low FPS on good PC

[humphreytt]

I started playing KSP on the 2012 mac book pro which ran it (albeit at low settings) relatively well for what it was. Now I'm not sure on the exact specs of that laptop but they weren't anything to write home about. In the summer of last year I purchased a new computer with considerably better components: Intel(R) Core(TM) i7-6700HQ CPU @ 2.60GHz 2.60GHz, 8.00 GB Ram, 64bit, GeForce GTX 960M. You should by now know, through the way I typed that, I'm no technical wiz kid but I do know it should be more than enough to run the game at at least low settings. However whenever I boot it up (no mods btw) it stutters to the point where it's unplayable. Incredibly frustrating. I've watched and read many articles explaining how to fix it. Even downloaded a performance fix. But nothing. I've racked up a considerable amount of time on the game and love it to bits but this  is making me want to build my own rocket and fly into the sun tbh. Please send help any information is much appreciated. 

Thanks

One possibility: some gaming laptops have a button to force the computer to use the integrated graphics rather than the dedicated graphics chip; make sure that's toggled correctly. Do you have similar problems with other games, or is it just KSP?

Potentially, you might try reinstalling KSP; the other possibility is that you're trying to control a 1000-part monster vessel, which will lag any computer.

The other possibility that springs to mind is that your computer isn't being cooled very well; at the least prop the back up to get airflow, and there are dedicated cooling pads.

I tried all of those plus fiddling around with my graphics card setting. Not sure which one did it but it's back to working at very good FPS now. So I thank you good sir for making my day!

I have the exact same specs and it runs smoothly, go to nVidia control panel, manage 3D settings, select KSP.exe (add it if it's not there) and set the "Preferred graphics processor" option to "High performance nVidia GPU".
