Bug #9578
Horrible FPS performance in editor; Maxes out CPU performance in Windows Task Manager
100%
Description
This was actually a problem for me in 1.1.0 as well, but it seems to not have been fixed, so I thought I'd bring up the issue.
Ever since the 1.1.0 update, the VAB/SPH editors have been really laggy, and seemed to max out my CPU performance (making it run very hot; around 60*c). As well as using 2gb ram, which I've never seen it go that high.
By laggy, I mean that every second, the game freezes for about a quarter of a second. Almost like it's jumping between 60fps and 10fps.
My computer has never had an issue running KSP, and it's still very capable.
SPECS:
i5 4570 @3.2ghz
16gb ram 1333mhz
R9 270x (GPU 1.04ghz/VRAM 1.4ghz)
I ran a FRAPS Benchmark while in the VAB with a ship made of 40 parts, and ran the camera around for 30 seconds. Here's the results.
Frames, Time (ms), Min, Max, Avg
2254, 30000, 48, 101, 75.133
Now, obviously I'm getting well over what I said it felt like I was getting, so I'm thinking it has something to do with it using ALL of my CPU usage, and making it physically lag, rather than performance lag.

Updated by UPDATE:
Just launched the ship out of the editor, I get a stable 80fps, and the CPU Usage is down to 60%-70%. Definitely the editor.

Could please you upload every file requested in the wiki, along with the craft file?

Issues that effect individual or small numbers of players are usually caused by hardware or software local to that player, in this case I would check to see if KSP is using a built-in Intel graphics card instead of the discreet card.
Performance will be poor when not using a dedicated graphics card.

There's really nothing I can send. It's not a specific craft file, or what ever. The editor is just, really laggy for some reason. :(

You could send the output log, KSP log, and DXdiag file, for one....

Its not as bad as in 1.1, but its still unusual high. CPU load in editor scenes is 2 to 4 times higher than in other scenes. CPU load increases with part count.
My system: i7 4790k
8GB RAM
nVidia GTX 760

A great deal of optimisations have been made for KSP 1.2. Overall performance should have been increased. However, this is machine and vessel part count dependant.
Performance impact needs to be re-appraised in KSP 1.2, so please retest to identify those areas that show the largest impact. Full machine specifications together with test vessels are required to identify potential weaknesses.
