Extreme Lag in 0.25

EDIT:

This has now been solved (thanks to slumpie).

Thanks to all who gave advice!

---------------------------------------------

Hello everyone,

I downloaded the 0.25 version of ksp (x64). I fired it up and was reading 1-5fps with dxtroy. 0.24 (x64) got 20-40fps (depending on if i was in a particle trail). I then tried duplicating my 0.24 settings file and replacing the .25 settings file with the duplicate. Still 1-5fps.

The System

AMD FX 4300 @ 3.8GHz

4.00GB DDR3 RAM

Windows 7 Home Premium x64

AMD 760g Graphics Chip (I really need a proper card )

Screen1: 1366x768

Screen2: 1024x768

Why is this happening?

Please help!

Hmmm. If I had to guess, I would be a lack of ram. 0.25 KSP uses more ram by default than 0.24.2 and earlier. You could try running with OpenGL as well as doing some Google searches and disable various Windows services you don't need running...for example, I disable print services since I don't have a printer at home.

And yes, a proper card would be better than the onboard ATI 3000.

Oh, and medsouz posted an unofficial build of ATM for 0.25 which you might want to consider looking into.

If possible, a lightweight linux like Lubuntu would be a better option if it really is ram. Less ram used by the system is more ram that could be used by KSP.

Thanks,

If lubuntu can be installed a bit like ubuntu used to be via something like WUBI then great! Otherwise :/

Ignore that ATM link above. Seems to be causing issues for other users and a fix is in the works. Have to wait until then.

It'll install with WUBI, but Ubuntu quit supporting WUBI earlier this year because it doesn't work with some Win8 bootloader setups. With your setup, you shouldn't have any issues using WUBI, though you'll either have to modify WUBI or install LUbu then do a bunch of updates afterwards -- it downloads the 14.04 release, not the 14.04.1, but that can be changed by some text file editing.

I'd advise reading up on WUBI issues before doing it.

I downloaded WUBI. It recognizes my windows 7 install as windows 8! WHAT THE F!?

[skeevy]

Well, Ubuntu did drop WUBI support a few months back. It could simply be because you have a UEFI BIOS on your PC, in which case, WUBI won't work for you.

About all you can really do is install Ubuntu normally. Shrink your Windows drive down about 30GB+ and install Ubuntu to that. You might need an extra 2mb bios boot partition. Just tell the installer to use that free space and you should be fine. Should being the key word.

Hello everyone,

I downloaded the 0.25 version of ksp (x64). I fired it up and was reading 1-5fps with dxtroy. 0.24 (x64) got 20-40fps (depending on if i was in a particle trail). I then tried duplicating my 0.24 settings file and replacing the .25 settings file with the duplicate. Still 1-5fps.

KSP 0.25 has an unhelpful habit of vaping settings files from earlier versions and replacing them with the defaults. I presume you ran 0.24 with reduced texture resolution and probably with other graphics settings reduced too so I suggest you check your settings in-game to make sure they are as you expect.

Earlier today I was running 0.25 on a 2.16 GHz CoreDuo with 3 GB of RAM and a Nvidia quadro 110M running 32 bit windows (so KSP could only use <2GB of memory) and I was getting about 2 fps in the main menu until I reduced the graphics settings to my pre-0.25 settings. Now I am getting similar fps to 0.24 (max of about 20 fps).

The Windows x64 version of KSP is badly unstable. I would highly recommend using the 32 bit version (especially if you aren't using mods).

I also downloaded x86 ver. For some reason, even with 0.24 settings, i still lag like crazy.

When's the last time you checked for driver updates? Not with Windows Update, but manually from the manufactures web site. A lot of times, especially with GPUs, those Windows Update drivers kinda suck (was true with my AMD R7).

It wouldn't hurt to defrag your hard drive either. I've had good results with Auslogics Defrag tool. I actually got a consistent 3fps boost with Skyrim just from doing a defrag.

Are these completely fresh installs?

What scenes (main menu, KSC, VAB, Launchpad etc) are you measuring this frame rate in?

Is your hard disk being accessed while in the game?

How much memory is KSP using (commit size in task manager)?

Can you upload an output_log.txt file from a short run of the game somewhere?

Okay. And I will upload log files. I used defraggler (took ten hours >.<) and it didn't help

Gahh!

[skeevy]

Post those logs. Sucks defragging didn't help any.

Have you tried deleting you settings file? That's helped others. Other than that, I think we've gone through almost everything else that can be done without logs.

And deleting the settings file did nothing

[slumpie]

No not that one, the outpup_log from the KSP_Data folder is the one that's needed.

The KSP.log doesn't tell much, I know it's annoying.

Could you also upload the settings file? Just to be 100% sure it's not because of that.

GPU/CPU clocks are stable? Temps are stable?

It doesn't start swapping to virtual memory?

KSP is the only process that's running on high load?

Well, that log isn't as useful as the output_log.txt, but I see you have just under 4GB of ram with an AMD processor. Here are try two things to try...

AMD Phenom processor

Phenom CPU's can still crash even with all fixes in this thread applied, this is due to the Phenom's Turbo Core technology which can cause instability in KSP. You can disable Turbo Core in two ways:

Add the following line to the target box of a shortcut after KSP.exe: "-force-gfx-st" (without the quotes)

Disable it in the Bios / UEFI

And if you haven't, reduce your texture quality to no higher than half. (It's in the main menu, settings, graphics tab.) KSP v0.25 uses more memory than previous versions. So if you are trying to use full textures, KSP may be causing your computer to do excessive memory swapping.

If you can, try to provide the output_log.txt. That might also provide some info. You can find out where it's at by reading here:

Also, GPU, MB and CPU temps stable thanks to those massive fans (found them from an old system I yanked apart).

I also set KSP to "Very High" in Task Manager. It helped in previous versions but not anymore :/

Can you provide both your old, working 0.24 settings.cfg file and your current 0.25 settings.cfg file? This really does look like your GPU is being overloaded either by texture size or possibly by polygon count...

You can't simply use your 0.24 settings file with 0.25 as 0.25 will detect some incompatible settings and will delete all the settings replacing them with the 0.25 defaults (which will almost certainly not run well).

Have you tried deleting the settings completely, reducing all the graphics settings in the main menu (set the texture resolution, the terrain detail, the pixel light count, the shadow cascades and the render quality level to minimum and disable terrain scatters) and then quitting and restarting the game?

[skeevy]

I just realized you're running a multi-monitor setup with only 1gb of vram. My card has 2gb of vram; with 0.24.2 and earlier I played KSP at 1920x1080 full settings no problems. I have to play 0.25 at 1600x900 because of the better textures and whatnot (back to 1080p after installing ATM and using some reduced graphics settings). Try running on only 1 monitor then do what Padishar said (or get a better GPU).

I used to do the exact same thing in Task Manager back when I KSP'd on Windows as well as tweaking my CPU affinity to run it on my last two cores. You'd be surprised how forcing KSP to work on two minimally used cores helps (true with Windows and Linux I've noticed).

Here is the 0.25 config. Values entered via the settings menu. http://pastebin.com/DSh1bffg

As for the multi display setup, I use it when playing KSP to do let's plays. They worked fine in 0.24. :/

[Lego8_bit]

im running the same exact cpu but I think what Is hindering you is your ram and your Grahics card. I can get up to 20-25 fps with my graphics card also Try running ksp on one screen see if that helps

Unity win 64 is unstable and buggy. To be fair and blunt thats your reason and cause: 64 bit. Run 32 bit until a stable win 64 bit is given.

I was running 32bit. Still was just as laggy (grr)

Disable SM3 Shaders

Enable Part Fallback Shaders

Restart game

[rodion]

Get a real GPU, dummy.

Let me try that

Technically it is a real GPU (ATI Radeon 3000). I am planning to get an NVIDIA GTX 780 if I can make some extra cash. School laptops take priority sadly.
