GPU - Usage

Seeing similar thing myself on multiple machines .. GPU does very little overall in the reconstruction of a block.

Machine scores nearly 200 .. lucky to get 5gpix a day out of it ..

Tried all manner of configs, multiple versions of drivers .. multiple machines with different cards (1080, M60) .. still can't get GPU doing little more than the odd burst.

CPU is maxed - all cores most of the time - some of the time single threaded (one core).

Tempted to say don't waste your money on GPU .. get the most and fastest cores you can - probably multi-cpu ..

Yes, I Mean Reconstruction. Some one mentioned that on "Accute3D Forum". I followed that and Configure NVIDIA. But still I have the Same Issue...

When you say processing you mean reconstruction correct? GPU is not used in the aerotriangulation step.

I havent seen this on a desktop before, but it does happen on laptops with integrated and discrete cards occasionally. In that case, you will open up the nvidia control panel and set the PhysX processor to use the card instead of autoselect or cpu.

192 Photos, 2.3 GIGAPIXEL

Executed On the work station ( 8GB Ram, NVIDIA GeForce GTX 980Ti Graphics card Core i7 2600K CPU @ 3.4 GHz 3.4 GHz ) Contextcapture rating of 138/100. The process time is 08 Hrs.

Executed On the Laptop ( 4GB Ram, Intel HD onboard Graphics card, Core i5 4200U CPU@ 1.6 GHz 2.3 GHz ) Contextcapture rating of 2.1/100. The process time is 12 Hrs.

Further during the Processing the graphics card usage is 1 – 3%. How we get Optimum usage of GPU?

Can you provide the size of the block in megapixels (select a block and go to "General" tab)?

Also, can you provide times for building a production with the graphics card and without it (presumable using the motherboards onboard graphics)?

This is an interesting (surprising) question and I too would like the answer, before investing in RC
