KSP now uses all my CPU cores

[GeneCash]

So for the longest time, KSP has used just one core for most of the game, and sometimes running mods like MechJeb in a second core.

I started up 1.5 and xosview and now it finally uses all 8 cores.

Nice! Thumbs up!

What!? I have to check that out next time I run the game.

well this is certainly something we could only hope for if it IS the case

 

if it is, all that's remaining is to ditch directX 9 and move to vulkan (and do something about the way KSP loads in all textures, even unused ones into the RAM?)

[MR L A]

This wasn't mentioned AT ALL in the change log (unless I missed it somehow)?

Can anyone confirm this? @SQUAD

[steuben]

I noticed that it felt peppier with a couple of my larger craft.

[Dafni]

I also saw no mention of this anywhere. But I dont read twitter and all that, my only source of KSP info is this forum here.

[jlcarneiro]

If that is true, it might explain why my computer did not warm so much...

I felt it "cooler" than it gets running KSP 1.4.5. But since I haven't used mods in 1.5 yet, I attributed this behavior to the stock version...

Generally, core usage is 99.9% controlled by your OS -- not by a particular application. So any change you are seeing is more likely from an OS upgrade, rather than a change in the game.

I can confirm that KSP is using all of my cores while playing now (never checked it prior to this so...idk if that means anything), and performance with high part count ships seems... better? (Possibly placebo affect I guess. I get pretty high frames regardless.)

There was a windows update recently, didn't really pay attention to what it did.

[Tyko]

@UomoCapra, was there a change to the way KSP utilizes CPU cores in 1.5?

Are all of your files still there?  *snort*

 

GoG finally updated with 1.5 Linux installers, so I'll have to do some side-by-side comparisons between stock 1.4.5 and stock 1.5.

Ooh! Shots fired! Lol.

Alright but how the windows update could change the way how unity based game uses CPU?

But if it really happened...

Yeeesh more modzzzzz

I've no clue, but I think we've pretty much established it wasn't a change on KSP's end. Pretty sure that would have been in the patch notes?

I have some older installs lying around, When I have time I guess I could fire one up and see if it only utilizes one core? That would tell us where the change is originating, if there is one.

[Ace76inDC]

Wow, if it's as you say I love it

[Rocket In My Pocket]

Well I fired up 1.3.1 and there was no difference, I see activity on all cores when running KSP and I'm not doing anything else.

Take from that what you will. For all I know there was activity on all cores prior; I never checked it before now.

Same here. Never checked before either as far as I remember, at least not with nothing running in the background.

It will turn out to be either a bug, useless unity shader or a bitcoin miner, won't it?

Probably should have mentioned this was Linux, not Windows...  (I keep forgetting Windows isn't as dead and buried as DOS)

Edit: from my Googling, this is a result of upgrading Unity

1.5.1 version still use 2 cores for physics and maybe +1 core for aerodynamics FX. I really want to see in next update optimization for all cores.

I, too, would absolutely love this; however, I also understand (even as a complete non-coder) that this would be a herculean task that would probably be limited by the work the Unity engine developers have done

I'd probably actually pay for that to be an update though..

[LukasKerman]

KSP always used all my CPU cores. Each just never went to 100% but stood at around 60%. I suspect that is Windows shifting the game's threads around the cores for an even load and core wear.

I think it's possible because there's PhysX that use a lot GPU cores (really a lot cores, 500 for example) for physics calculation.

Yeah but that's basically GPU acceleration, not CPU multi-threading. They are two very different things - and yeah, of course it's possible, it is just a hell of a lot of work - and not work that SQUAD can necessarily do anything about considering they don't own the Unity engine.
