Why should it have any? When your PSU can't give your GPU the requested power anymore it makes not difference to ask only for the needed amount of power or everything available.

overheating of GPU? (install GPU-z) Peak power consumption to high for PSU? How many FPS you get overall? ("debugInfo=true" in cfg)

The PSU delivers 850 W. Should be enough for the GPU, no?

I changed debuginfo to true in the config. Where can I read the frame rate now? It does not say anything on the screen or in the log file.

See here viewtopic.php?f=21&t=7088&start=140#p93325 , left bottom corner. Alternatively install FRAPS.

Install als gpu-z to ditectly see the gpu load and temperature

Not sure what exactly you mean in the left bottom corner...

Ok, I did some fiddling. Here is what I found out in the meantime:

- The problem is not the PSU.
- The problem seems to be the GPU to overheat.
- GPU A goes up to 102 degrees, then the system crashes.
- GPU B stays safe in the 40s and 50s degrees.
- I turned the fan to maximum, removed the casing of the computer, put a 40 W desk fan next to the computer pointed towards the grafic card.
- In Nvidia Settings, I forced PhysX (whatever that is) to use GPU B
- With those last two measures combined, I managed to keep GPU A to hover between 100 and 101 degrees (i.e. just under threshold where it crashes), while GPU B climbs to 90 degrees.
- GPU load A is in the nineties, GPU load B is zero all the time. Fan A speed is at 95 % all the time. Fan B speed is at 0% all the time (I assume there is only one fan). Video engine load is 0% at both GPU all the time.

Any ideas what else I can do?

GPU load A in the nineties and GPU load B zero all the time tells me that your SLI setup is not working. There is no SLI profile for the game so you have to set it up yourself to get SLI working. You really should check out hansmuff's findings. It might help.

Next you should go into the game's option menu and enable either "Vsync" or (better) "Triple Buffer" to prevent your GPU from rendering more frames then necessary (a.k.a. your screen can display) in any display mode the game offers. Reason is that otherwise the game will ask your GPU's to render up to 120 FPS due to it's default fps limit and with not much to render in the beginning your GPU very likely does that.

The important question here is: which FPS rates do you get?

You can check this with either FRAPS, any other FPS measuring tools of your choosing or by setting the parameter "debugInfo = true" inside the game's config file grimrock.cfg to have the game display it's own FPS meter in the bottom left corner of the screen once you're in a game.

For example in the early areas my GTX 760 easily hits that 120 FPS limit when "Vsync" (or "Triple Buffer") is not enabled. Naturally this will consume a lot of power and push my GPU's temperature to 70+ degrees. With "Vsync" (or "Triple Buffer") FPS match my display's refresh rate of 60, the power consumption is almost halved and temperature is in the low 50's while the game plays exactly the same.

So both of these simple settings should help if you're using 60 Hz displays. In case your displays operate with higher refresh rates you can limit the rendered number of frames to 60 (or less) by editing the game's config file. To do this modify the "maxFrameRate = 120" line inside grimrock.cfg.


About that forcing PhysX to GPU B:
as far as i'm aware of the game does not make use of nVidia PhysX so this setting should not have any effect.

About GPU B idling around 40 to 50 degrees:
this seems too much for an idle GPU. When it has nothing to do temperature should not go above 40, let alone 50. This might be a sign for a lot of dust being caught in the card's air ducts and fans.

EDIT
One more thing: update the game to it's current version of 2.2.4!
The log you posted earlier says you're still running version 2.1.3 which is an old beta release candidate!

You are right, there was lots of dust in the GPU! I cleaned it throrughly. Now the temperature is between 60 an 80 degrees, so no more crashes, even at full detail level. Also, the whole systems runs much quieter due to the fan running only at half speed.

And just to complete it: FPS is 60, it also says 16.7 ms (which is probably a second divided by those 60 frames). Vsync is enabled in the game and set to "adaptive" in the NVIDIA settings. Game version according to the opening screen is 2.2.4 - now idea why it says 2.1.3. in the config.

Thanks a lot Dr. Disaster and all the others for your help and patience! And now for some serious monster slashing....
