AMD RADEON slow response big dataset

[Peter]

On my dual 7970 setup when i generete on high setting and 66mil faces agisoft stops responding, is this to much for the cards to handle?

Is there a driver fix for this?
Would nvidia be better f?r desktop viewing than radeon?

I don't know sth about 66m processing stuck.  Probaby, Alexy will ask you to send the photos. 

I can't say Nvidia is good in this case..  Your 7970 is a good solution..
Does only agisoft stop responding? Can you terminate agisoft, Does pc keep working?
On the other hand, make sure your hardware is good enough... Especially power supply.

I think agisoft is doing fine, i changed topic.
If i change to point cloud i can rotate model just fine.......i found some old post that there where problem with 7970 and Vbo and handlig large datasets.....

But later on in the same post i stated to be fixed and that there would be fine to handle large sets like with nvidia cards.

I have latest drivers now, i will try to decimate mesh to 40 mil and see.

I have 1200 w psu

With 40mil it is going fine with VBO enabled

You are running into the memory limit of your graphics card. Not much you can do, except buying a GPU with more memory.

Sometimes it also displays the model, but leaves out every second polygon (so your mesh has tiny holes in a checkerboard pattern).

Yes that is probably the case, i also noticed that my two 7970 anly show 2 gig om memory in agisoft.....strange as they have 3 gig each.

Has anyone encountered this?

Good catch, I never gave it a thought but now I took a closer look and my 7970s also report 2GB in agisoft, despite being 3GB cards. 

I remember having similar problem with Autodesk Mudbox, where they suggest manually changing some (Mudbox-specific) System Variable in Windows...

I sure hope there is a way to reclaim that 1/3 unused memory in Agisoft...
