Stuttering (not enough RAM?)

Question

Hey guys!

I'm running an, i would say moderatly modded install of KSP ver 1.3.0.

The issue i'm having is a stutter which appears periodically in uncomfortably short intervals. 

My question is if the problem is simply my lack of RAM to run all these mods or perhaps something else? Also if it were the sooner do you guys have any recommendations on which mods to exclude form the list, which ones are considered RAM heavy?

Here is a video recording the issue: (excuse the low frame rate i recorded it full HD @60 fps it was a bit demanding for my rig)

My specs.: Acer Aspire v3 772G Laptop with an i7-4702MQ @2.2GHz (3.2GHz turbo), 8GB of DDR3 RAM and an NVIDIA GeForce GT 750M. The game runs from a Samsung SSD.

Yeah, I don't think it's your hardware showing cracks so much as it is the game itself.

Also; I'm pretty sure the game still has the long running memory leak on craft revert it's always had as well. Which will tend to increase RAM load as you play over long sessions. (Especially if you do a lot of reverting while testing like I do...)

For now, just restart the game every hour or two. That's the strategy I've adopted for now anyways lol.

Unity garbage collection, as I'm sure you know; since you have Memgraph.

The good news is this should be fixed in 1.4 as I hear. The only solution I've ever found in the current version of the game besides Memgraph which helps for a bit, is to restart the game periodically. (Removing mods will also help of course.)

Maybe a shot in the dark but; are you actually padding your heap with Memgraph? You have to press Alt+ End after you play for a bit. You gotta do this every time you play the game.

That would be te best fix in very long. :)

Yes, but those are posts form 1-2 years ago on later versions and i think i read some already. It's similar nontheless indeed.

Yes i suspected that. I actually padded it halfway in the video as well. Isn't there a more convenient solution to that maybe a config file where i can set it higher though?

My only concern is that i had even more heavily modded installs in the past without this issue being so prevelant. I wonder if it's perhaps a memory-leak.

It's hard to go through and "rate" each mod since I've only used a few of the same ones as you.

As general advice though; Any mod that adds parts is going to heavily increase RAM load, as it has to load the textures and what not for those parts into your RAM at launch. (This is also rumored to be on the "fixed" list for 1.4 as the new Unity version supports dynamic loading of assets.)

Any mod that is doing a lot of calculations (Trajectories would be a good example) is going to increase CPU load quite a bit.

Yeah i know i actually got rid of a lot of part heavy mods before i finalized this modlist. I would say it shouldn't be too heavy on the part heavy mods side currently.

It's absolutely impossible to play without the Trajectories mod :D Yeah i think i'm good on the CPU as well. The recording did crank it up quite a bit but it runs even the modded installs smoothly.

This is very sad. It always was.
Last session I did a lot of reverting and switching vessels over hours. At the end KSP demanded 21 Gigs (it was 14 at launch).
