My Multi-Threaded Woes...

[BustyLoliChan]

I realize that this has been posted before...

I realize that it's not exactly an easy fix, and that maybe right now there isn't exactly much that can be done about it

But this is by far my biggest complaint/problem/issue with this game...

Here's what I'm working basically...

I have a 4.01 GHz hexacore processor

One Powercolor Devil13 7990

And one XFX 6970

I have 16 gigs of ram

I have 700 GB of Solid State Storage space

I have 3 Terrabytes of regular disk space

And my entire system is water cooled...

I can play Crysis 3 on maximum settings

I can mine Litecoins at 1.8Mhash/sec

And I still cannot run this game at 60 fps

And that genuinely frustrates me...

It could be the fact that I like to build a lot of big things....

I have at least 2 ships I've built that have over 1400 parts...

I have a couple others that have over 800 parts...

Maybe my hopes, dreams, and design ideas are in the wrong place...

I know that this game is an early access...

I wasn't promised anything...

I'm not entitled to anything....

But the fact that this game lacks so much multi threaded support and the fact that even with this rig, I am unable to run this game at any decent framerate genuinely disappoints me, and I just honestly find it unacceptable.

It's like I really want to like this game, I really do like this game, but when it comes down to it; It runs like crap, and I see it as such...

until this is fixed this game = crap

I'm sorry to be so negative about it

This'll probably be my one and only post

but that's basically my feedback and feelings about the game at this point in time...

The lack of multi threading support is terrible, and while I can enjoy the game from time to time it really keeps me away from it and makes it a dull lack luster experience; but hey, at least you already have my money...

The game is a work in progress, and performance optimization is not a priority at this point in its development. Not all of its major features have been implemented yet, let along optimized. That being said, they've made some big improvements in the last couple of versions. Anyway, if you let that kill your enjoyment of the game, you're only hurting yourself.

Welcome to the forums!

Multicore support has been suggested several times before. Unfortunately, that seems to be an issue that's out of the KSP development team's hands, since the version of PhysX used in the current build of the Unity engine doesn't support multithreading at this point.

I know it's a bit of a cliche at this point to foist the blame on someone else for this, but for the moment the devs' hands are tied.

[vger]

The newest version of the engine supports multicore, or so I heard. So hopefully this problem will remedy itself soon enough.

[stupid_chris]

KSP is already multithreaded. That's not the problem. The problem is that the Unity API is not thread-safe. That means a single task cannot be splitted across multiple cores, but multiple cores can be used to accomplish multiple different tasks. Namely, physics calculations, are by far, the biggest thread, and it's big enough to clog up a full core on it's own. Unfortunately, it can't be split across multiple cores. The only solution is to have high clock speeds so that the core working on physics can run it as fast as it can. I think Unity 5 fixes some of the thread-safe issues, but we'll have to wait for it to actually come out.

i have an i7-3770 at 3.7 ghz, and a evga gtx 660, and 8gb ram and i dont have any issues running this a full settings with great framerate. you got updated drivers?

edit: OP's name is hilarious.

OP is no doubt building ships with big part counts, which will cripple any computer known to mankind. Try that raptor and you'll see the yellow time slow mo.

[KvickFlygarn87]

How many mods do you have? KSP will have trouble with high part counts. Try building smaller. Efficiency is key

P.S. Welcome to the forums!

P.P.S. The fact that you have three dots after every sentence bothers me

[Rarity]

That's what happens when you get an AMD processor; awful single thread performance. Honestly, though. Did you build your system yourself? Why get a high end rig everywhere but the CPU?

[Alewx]

Unity used to have physx from NVidia, should than the physics loop not be done by the GPU instead of the CPU? My last unity experience the api is blocking mutlithreading so KSP can only have it if squad did write like all the classes itself again in C#, also my rig is quite similar and I always see only one core beeing used. I have more the problem with the RAM, with too many mods but that is known as an Unity problem, that the memory management is not really the best, but that all does not bother me anyway.

@stupid_chris

Has squad any plans to change to Unity 5, or is it likly they stay with version 4.3.x to keep updating mainance of the code small?

[vexx32]

Alewx, Squad will very likely keep as up-to-date with Unity as they can manage. If there are issues, they'll just iron them out as best they can before making a public release on a new Unity version.

[rkman]

It is to be expected that a game that's been out for a year runs better than a game that is still in development.

until this is fixed this game = crap

You'd probably think the same about Crysis 3 if you would have played it while it was still in alpha.

It's likely they will, but don't quote me on that. I have absolutely no idea, and no one except people that have access to the developpment process itself could potentially know.

Ok thanks, was just nosy:)

O Lawd, OP's username...

On a serious note, given that KSP is quite sensitive to single-thread performance, would it make sense to disable hyper-threading if using an Intel CPU?

(I realise this is no use to those with AMD CPUs.)

Yes, and no. Just disabling hyperthreading isn't going to make any difference, at least not in KSP. But if you're overclocked, then disabling hyperthreading can shave a few degrees off your operating temperature which would allow you to raise your clocks just a bit further and get some more frames in KSP.

Lighten up, Francis.
