Very Low Framerates Spontaneously

[GreyGriff]

I'm getting very poor framerates all of a sudden. Yesterday I was playing the game a lot and had no issues whatsoever. Today I restarted my PC and now the game is dipping into the 10-20 fps range after a minute or so.

When I start the game up I'm getting 60 fps easily and even into the first part of a launch everything is fine. However after a few seconds of flying it dips to 10-20 fps. I've restarted the game and the PC a few times and the same thing happens each time. I've even reinstalled the game, reset settings.cfg, and tried running with force opengl and force dx11. 

Here is my hardware:

i7 4.00GHz

12 GB RAM

Nvidia GTX 970

Crucial SSD

I've tried lowering some settings but no go. I should be able to run it fine with the highest settings tho, I was doing it just yesterday. I have no mods installed.

Can you check if Windows is updating?Sometimes that causes me sudden problems without even knowing it.

You can also try opening task manager to see hows the memory/cpu percentages going.

Other things might be temperature problems, do you have similar experience to other games?

This has been a culprit in the past, especially with laptops. I've also heard it happen with PCs when the fans stop working or the heat sink doesn't have proper thermal putty. (KSP can be rough on processors and graphics cards.)

Also, if you updated KSP or your graphics drivers recently, check if KSP is still using the proper video card. Sometimes the nvidia 3D settings lose track.

 

Does this happen with any vessel, or just some particular ones?

 

Also, take a look at the log file and make sure it's not getting spammed with messages. If, for some reason, you have a corrupted ship or part in the save, it can cause excessive log entries which leads to slow performance (because the computer is outputting so much to the log file).

Which version of KSP are you using? I had the same problem of 20 fps in 1.7 and 1.6, but no problem at all in version 1.5...
