ksp uses WAY TOO MUCH RAM

[tonimark]

as result the hard drive is overloaded for a very long period and ksp performance is minimal

[Pena]

Or maybe you will need to change your settings or get a modern PC with enough memory to run the game. Tons of mods will of course increase memory usage hugely.

Moved to technical support, as it seems it might be a problem on your end, @tonimark. 

With that in mind, please post the details asked for here:

 

[tonimark]

why is this a problem you may ask ?: because despite it takes  40  minutes of initializing it takes another 30 minutes for the start menu this is extreme performance drop , but the game crashes reporting something like steam error this happens due to autocrash occured because the steam gets shutted down by the system from excersive ram usage which totally makes the game unplayable how the performance drop ?? simply by virtual ram the system uses the hard drive as a (secondadry) ram and the ksp won't be playable the recommended ram specs for kerbal space program is 4GB (and i have 8gb) (and disabling virtual ram will result in a BSOD in intializing) mods installed (70 total) , :

Like people have told you before: use less mods. Don't just shove in every available mod you can find.

ok i have now i new problem

[Anth]

Should start off with stock. Then watch the memory usage over an hour or so. 8GB is inadequate for KSP currently.

KSP will start getting weird when its fighting with Windows 10 for ram

[ShakeNBake]

8GB is totally inadequate for a mod list of that size. Bone stock KSP runs fine at 2-3GB.  I only have 20 more mods than you and my install would overwhelm most machines.

[jimmymcgoochie]

Running a large list of parts heavy mods on an older/less powerful PC will obviously make the game run slowly. Be ruthless and cut down on your mod use: scrap anything you don’t absolutely need, sacrifice some crafts if you have to to ditch another mod and close everything else on your PC to keep the memory free. Not sure why you need all those mods for the stock solar system, especially KSPIE which is monstrous overkill. I can regularly use 8 or in some cases 10GB of RAM running KSP.

The game loads everything in when it starts so having many gigabytes of extras will cause very slow load times especially with a slow hard drive. Again, removing what you don’t need will help with this and you can delete parts you don’t want/need from a mod and just keep the few that you do.

RAM isn’t very expensive so depending on your PC it might be possible to upgrade your PC relatively cheaply which will make the game run faster; likewise a small SSD isn’t too expensive and it will make a big difference as SSDs are much faster than a conventional hard drive and even an external SSD running through a USB3 port could dramatically reduce your load times. The best (and cheapest!) option is still to reduce your mod count, getting rid of anything you don’t desperately need and then keeping it low despite the appeal of shiny new mods (or when Kopernicus gets 1.9.x compatibility as planet packs use a lot of RAM too).

[Kerbart]

Having multiple versions of the same mod is not the problem, but indicative of the root cause: not making any selection in installed mods at all.

 

Try running KSP without mods and then add the ones you really want back in one by one. Part mods tend to come with texture files which gobble up memory rapidly, so be extra selective with those when you have limited system resources.

 

[tonimark]

after some reserach decreasing texture quality have helped a lot no more hdd overload
