Kerbal Space Program

I highly doubt the issue is with KSP, if your monitor is going into standby.

On the contrary it is the only application that has this effect.
No other game or application shuts down my display, no matter how fast I make it run.

However the monitor might shut down because of a result that terminates the video out signal.
And in turn the monitor decide to safe energy to shut the monitor down because there is no video signal any-more.

I only have one monitor, so it is not that a monitor signal is swapped to a different monitor.

It clearly started with v0.22 and now 0.23, 0.18 did not have this issue.

I did not have time yet to determine the cause, since all I can do is terminate the power from my computer to reboot. Pressing the physical power button that normally initiates a shutdown of Windows seems not to do anything anymore. Maybe the whole computer just froze.

When it happens, does the numlock light stop responding to pressing numlock?

Are the video drivers up-to-date?

A software application in userspace, I'm pretty sure, doesn't have the needed privliges to terminate the video out.

Unless MS changed it, the next time it happens, press SUPER+L, where SUPER is the key most commonly indicated with the Windows flag. If you hear the switching-user sound, the system isn't getting locked up. If the graphics don't return at the login screen, it is NOT a KSP-based issue.

I might also recommend running in a window.

Right now, I'm tempted to state it is a dupe of #1836.

Could you use software such as MSI Afterburner to check your GPU temperatures during KSP gameplay?

If you use it in full screen mode, then I would say that maybe the game switch to a resolution/frequency what the monitor is not supporting, so it switch itself off.
As a first step I would say try to run it in windowed mode.

Just to note, all the displays I've used report visually if they get put into an "invalid" frequency. This includes an old Dell CRT, a Compaq CRT, an eMachines CRT, a couple of HP LCDs, but not the LCD in my laptop (due to Windows understanding the resolution it has, and me not being able to force a bad signal over a video line). This actually also includes several TVs and projectors (when using a VGA line).

If you are at all curious as to how I force a bad signal, it involves using a microcontroller to make a video signal.

In any case, a display should report about a bad resolution.

Usefully, as of Windows XP (I haven't tested 7, due to me keeping my laptop at the full 1366x768), Windows looks to have a systemwide resolution (used on the login screen), as well as the per-account resolutions. In theory, if the game is just giving a bad resolution (which wouldn't result in sound stopping), the Super+L "Switch User"/"Lock" KB shortcut would switch to the systemwide resolution.

In any case, we need more information.

I will try to find some more time to find how to simulate it.
But I can tell you follow things.

• It is only KSP no other game gives this issue no matter how the GPU is loaded.
• It is on Windows 8.0 64 bit.
• It is in a windowed frame, not full frame.
• The shut down of the monitor might not be a GPU related but maybe something is halting the CPU or crash windows
  --> Music stops, power button does not shut down Windows, the keyboard seems not to do anything anymore.
  --> Effect is the screen gets completely black, and the screen LED changes from white to orange.

So far I appeared to have it when I am de-orbitting and almost at ground level.
However last time I got is was when I got into orbit. Suggesting that it is time related.

It is interesting that I appear to be the only one that has this issue.
However I doubt that it is a temperature problem, or a hardware related issue.

If there are any tracing options that I can activate please tell me.

Super+L has no effect, keyboard light also does not alternate when I press shift and num lock.
I do hear the music from KSP.

The test screen is the screen where you can select buildings. I am not testing with a real launch.

Low res, max dimensions and max res low dimensions gives the black screen after about 2-5 minutes.
Low res and low dimension appears to make KSP run way longer but eventually also turns in a black screen.
The GPU ventilator sound like average speed. Now where near the max speed when I stress it with any other game.

The problem is only in KSP. I do not recall it ever seen it with v0.18 where I maxed the settings for many hours in a
row.

Drivers, windows all updated to the latest drivers.

I have a strong hunch that you you have a resource leak but I do not have the tools to test this.
Normal CPU speed stays constant, and CPU memory too.

I will try this MSI afterburner. (Never used it)

Note that temperature is in C. Your card is definitly overheating. Try lowering your graphical settings, improving airflow, or getting a new GPU.

Problem isn't KSP itself, it's just that KSP has been using the GPU the most

I am already at minimal settings.
So for me this means no more KSP since it is overheating and at this moment no money to upgrade the computer.

Unless I get the 0.18 back, that one was working in the highest settings.

But thanks anyway. KSP is really great. :-)

• Check that the vents on the back and/or side of the computer are not obstructed
• Clean the dust from the inside of the case, especially around fans
• If it is sufficiently cool in your enviornment, and you are careful, it might be possible to run your system with the case open. * A desk or window fan could help circulate air

Also, a quick search online reveals http://preview.tinyurl.com/mw5qfvh (nVidia's domain), which might help with your specific card. Also see http://www.youtube.com/watch?v=sjfjnuiCf04 , which explains how to clean the dust from the fan on your GTS240 (while the log indicates that the fan speed went to maximum, I surmise that it only shows what the system is trying to do with the fan, and doesn't report the actual fan preformance)
