[Fixed] 32-bit runs fine 64-bit is super laggy and low FPS. x64 uses integrated graphics only for an unknown reason

[Racescort666]

After realizing that I was still running on 32-bit 1.1, I started using 64-bit and immediately noticed a huge performance hit super slow FPS, yellow clock, et al. I tried switching back and forth, 32-bit runs fine, 64-bit runs like manure. 

After some tweaking it started to feel like a graphics problem which led me to check the logs. 32-bit log shows using my NVIDIA graphics card, 64-bit uses integrated Intel graphics. I checked the old logs from my previous playthoughs, all used the NVIDIA.

Specs:

OS: Win7

KSP: 1.1.1.1250

CPU: Intel i7-4810MQ @ 2.8 GHz

GPU: Intel HD Graphics 4600, NVIDIA Quadro K3100M

I will admit that I don't have that much experience with this so I changed the settings in the NVIDIA control panel so the global settings used the NVIDIA card as the preferred. I also tried it under program settings and this doesn't seem to work either, KSP log still showing Intel graphics.

I'm not sure if this is a bug or if I'm doing something wrong that's not related to KSP or if it's something completely different. Help is appreciated. Output log here.

Same problem here.

Both old lightly modded 1.0.0 install or current unmodded 1.1 install work fine if launched with x86 executable, even with almost best graphic options: I just experiment time lag and few FPS when manouvering in atmosphere BIG +50 parts rockets. Of course I would love to build huge rockets and stations so I tried the x64 executable of new 1.1 install (installed and patched with GOG) hoping for the FPS miracle everybody is talking about.

Well, this same new UNMODDED 1.1 when run with x64 executable (and even lowering graphic quality to average-to-low rates) is SUPERLAGGY and runs with FEW FPS EVEN IN MENU. In spaceplane reentry scenario, FPS is around 2-3 per second, while the "time" is slowed down some 3x or 4x. It looks like even controls are lagging so if you just press "q" for a fraction of second, the plane could roll a lot, or not roll at all. However. Map view seems to work much smoother.

In the log file I can read dozens of errors, but I can't understand what are they referring to. I may post the whole log file but it is huge, maybe there's a way to cut it or produce a "cleaner" one.

 

Please help us!!!!

[BELOW IS A MISTAKE, I LET IT HERE FOR COMPARISON. THIS LOOKS TO BE THE x86 LOG. CHECK BELOW FOR CORRECT LOG]

Not my case, it clearly reads:

Initialize engine version: 5.2.4f1 (98095704e6fe)
GfxDevice: creating device client; threaded=1
Direct3D:
    Version:  Direct3D 9.0c [nvumdshim.dll 8.17.12.6874]
    Renderer: NVIDIA GeForce GT 555M  
    Vendor:   NVIDIA
    VRAM:     2014 MB (via DXGI)
    Caps:     Shader=30 DepthRT=1 NativeDepth=1 NativeShadow=1 DF16=0 INTZ=1 NULL=1 RESZ=0 SlowINTZ=0

OOOOPS. I checked the wrong log: this is the correct one:

Initialize engine version: 5.2.4f1 (98095704e6fe)
GfxDevice: creating device client; threaded=1
Direct3D:
    Version:  Direct3D 9.0c [nvumdshimx.dll 8.17.12.6874]
    Renderer: Intel(R) HD Graphics Family
    Vendor:   Intel
    VRAM:     880 MB (via DXGI)
    Caps:     Shader=30 DepthRT=1 NativeDepth=1 NativeShadow=1 DF16=1 INTZ=1 NULL=1 RESZ=1 SlowINTZ=0

So yes, the problem seems the same of @Racescort666

1.1.1 has not fixed this problem. I updated the drivers thinking that might be the problem but this did not fix the problem.

I fixed the issue by disabling hybrid graphics in the bios and basically forcing it to use only the NVIDIA card all the time. @monamipierrot I fixed mine by following this procedure: http://support.hp.com/in-en/document/c04070522 It disabled the integrated graphics and booted up in 800X600 downloaded/installed a bunch of drivers then required a restart. After the restart, everything was back to normal except only using the NVIDIA card. 

I haven't tried re-enabling hybrid graphics to see if it will function as intended (switching between cards as necessary) but I'm fine with running off of the dedicated card.
