GPU is not important?

[lgs777]

Only Cpu working in photoscan?  Align Photos ,  Build Mesh and texture ..
GPU is jobless??  My english is bad

Correct, the GPU is only used for the Dense Cloud reconstruction.

But it speeds up this part a whole lot, without a GPU the Dense Cloud reconstruction will take maybe 10x longer.

50 times longer on small datasets ( 100 imgs ) comparing to say 7970 or 680

Hello, one issue I'm having for some time is that when I want to go to the GPU settings, PS crashes immediately.

Why is this?

Hello,

try to update your graphics card driver with a newer one.

Hello, another reason of PC-crashes is might be GPU overheating. Try GPU-Z and monitor the temperature

I do have the newest driver version. nvidia 340.52 presently.

I'm using GEForce GTX 660.

Photoscan still crashes when I try to open the GPU rider in the 'preferences' window.

OK, two more questions

- do you use the latest version of PhotoScan ?
- you had the latest driver the hole time ?

Best regards,

Alex

[Patribus]

yes, I have the 1.0.4 version which I have been using since it's release.

The NVIDIA drivers are not always up-to-date in my case, since some of the upgrades fail, others not. But presently the drive is the newest one.  But to answer your question: no, I did not have the newest driver of NVIDIA all the time.

Cheers

Well, if you are not using win 8, I'm short of ideas. 

The one thing that caused issues in another application was onboard ( CPU based ) graphics card. After disabling it in BIOS everything was ok.

Best regards,

Alex

[Patribus]

Yes, that should not be the case on my PC.

But thanks for your time.

[mobilexcopter]

It's nothing. 

I did notice however, that the issue is allready discussed in Bug Reports area so I suggest it is continued there to avoid cross-posting.

Best regards,

Alex
