Quadro FX 3800 support

[Simon_]

Hey guys,

i found an old NVIDIA Quadro FX 3800.

When starting Photoscan on Win10/Ubuntu 16.04 with the latest NVIDIA drivers installed everything works fine, no Errors in the Console and Terminal window.
Also no OpenCL Error as mentioned here: http://www.agisoft.com/forum/index.php?topic=6163.0


But the GPU will not be listed in the GPU device list.
I found posts where Photoscan was used with this GPU.

Was the support dropped?
What was the last working Photoscan Version with this GPU?

Thanks, regards
Simon

Hello Simon,

Can you copy the log output please, can't see the text on the screenshot.

Please also note that version 1.3 uses CUDA by default for NVIDIA graphic cards, not OpenCL, like in the previous version.

Just checked the specification and it seems that Quadro FX 3800 has CUDA compute capability 1.3 (https://developer.nvidia.com/cuda-legacy-gpus), whereas PhotoScan requires CUDA compute capability 2.0.

I compressed it too much, sorry!

Thanks Alexey!

Can you point me to an older version which works with this GPU?

Hello Simon,

I think version 1.2 may work, as it used OpenCL even for NVIDIA cards.

Hello Alexey,

were can I download the version legally?
A search with google reveals questionable sources only...

I have got Version 1.2.7 from Alexey.

It works with the GPU flawlessly and also slowly, because its from 2009 and modern hardware is much faster...

Thanks for the support Alexey!
