Huge loss of performances since 1.1

[Tatonf]

Hello.

I played KSP for 3 years, and had no problem at all with performances (except when trying to make a 500 parts ship, but that was expected).

Until now.

The very infamous long awaited 1.1 version is a huge pain for me.

Now I can barely play it for half an hour, and then my fan goes crazy like if I were asking him to run The Witcher 3 in ultra, I experiment freezes and big frame drop.

I tried to lower the graphic settings (which I SOULD NOT HAVE TO DO with a GTX 970M), but the results are the same.

I don't know what's going on, but PLEASE do something ASAP. I can't play my game anymore.

Thanks for reading.

We cannot help without more info, sorry.

Though it sounds most likely to be the common "my laptop isn't using the dedicated GPU for the 64bit version of KSP 1.1" issue.

If this is the case then the logs should show it using an integrated GPU (e.g. an Intel HD) instead of your NVidia one.  You should be able to change your video card configuration to always use the NVidia card for KSP_x64.exe.  There are links to more info in the following thread:

As the issue appears after a half hour of play it is likely to be something else, hence the need for the logs.

[Padishar]

It is also possible that the extra stress on the integrated video could be causing the CPU to overheat after a while and thermal throttle.  Or it could be the issue seen during the pre-release where an 8 core CPU suddenly starts using all 8 cores for no apparent reason.  Or it could, like you imply, be something that might actually show up in the logs...

KSP seems indeed to be using my nvidia card.

I'm trying to reproduce the lag to get a log to send you, but even though my fan still run crazy I've not been able to reproduce it yet.

It happened 3 times in a single day so this is why I've posted a topic.

Looks like a temperature problem.

You're using a laptop, and since physic calculations are done on all the cores of your processor now, its not a surprise to see an increase in temperature in your processor.

Clean up the fans and make sure your processor isn't overheating (making it throttle down and resulting in bad fps).

(PS: Forgive me my bad English)

When was the last time you cleaned your PC/laptop of dust ?

I am also experiencing this issue. I have a desktop with a GTX 970 card, quad core processor, windows 7, and I was running KSP pretty well all along until right after I installed 1.1 today. I tried restarting my computer and clearing some memory but it didn't help. The game starts to overheat my computer about as soon as I load a save file, even just idling at the space center or in the VAB with no craft loaded will cause the fan to spin up like a jet engine prepping for takeoff. The task manager shows me that all 4 cores are running at about a 60% average at all times while the game is loaded, even though they are pretty much idle with the game off--when I'm not running Mozilla Firefox that is. Closing Firefox does not help the game run any better, and I can't see any reason it would run all 4 cores at 60% when I'm doing nothing.

I would say its not that much heat issue, its rampart memory leakage all over the place?!  From 1.1+ FPS over all are considerable better, makes me so happy. But there is something happening with memory, assets loading in game, vab menu changing, right click on parts, its slower, depend on situation but there is some kind of lag now. Regardless of having 50+ mods, etc, there is slowdown compared to 1.05.     

[sal_vager]

@thereaverofdarkness2. your graphics driver is out of date, you can find the latest here.

@Hrv123, please try without mods.

And make sure KSP is using your graphics card, not a GPU built into the CPU, you can do this in your graphics card software.

[Padishar]

The VAB is known to cause oddly increased CPU usage over other scenes, 60% on a quad core being about expected.  I would recommend running a CPU temperature monitoring program to see what sort of temps you are getting as you may have poor contact between your CPU and heatsink.

I already installed the latest one shortly after I made that post, and it didn't have any effect.

On the NVidia Experience panel I was able to pull up a page for KSP which showed the recommended settings for my rig. They appeared to have settings from before the 1.1 update but it only told me to turn them higher than I had them, in some cases higher than the new UI will allow. It recommended 64 shadow cascades, for instance, while it only goes up to 8, and apparently due to some other change, even at zero shadow cascades the shadows look excellent and sharp.

 

I checked my CPU core temperatures over several minutes and sitting idle in the VAB they were all 4 running yellow at ~80-90ºC. When I built a very basic craft using no more than a dozen or so parts, the fan spun up even higher and the temperatures rose past 90, getting close to 100.

Maybe there is some issue with the heat sink, but it can't be that bad because no other program does this to my computer, including KSP before 1.1. The only thing that even came close is the Minecraft forums which are phenomenally poorly constructed and cause my CPU to spin up to high numbers to load nothing but junk graphics that are not only excessive for a forum but also should load far more easily. They don't know how to write code. But there are no games I play that stress the processor. Minecraft, WoW, Path of Exile, EVE Online, Starcraft 2, Diablo 3, Wildstar, Starmade--all these games run fine at high settings. You might say that these aren't the most graphically intensive games out there, but I would say neither is KSP. I have a copy of Metal Gear Solid 5 I haven't installed yet, maybe I should try running that and see what this rig can handle?

edit: Actually I don't have a copy of MGS V because NVidia doesn't want to deliver on their promises. Yet another reason I don't like to deal with the triple-A developers.
