I have the K5200 with latest drivers from Nvidia.
Which card are you using?
Under the processing options under resources you can uncheck the grsphics cards. I was thinking the pix4d note I saw was the quadro drivers were effecting step 3.
Dual GTX 970. Interesting the latest Driver for the K5200 was released on the 18th I wounder if you go back to a pre Pix4D 2.0 driver. Sorry I do not have access to a Quadro card to test.
I donât think I updated the card during July.
Where did you see the latest drivers link?
Saw the option for disabling the CUDA.
If you uncheck it though, be prepared it will take a while to process with out a video card.
I have a Quadro 4300 and GeForce 970 but always uncheck the quadro. I have asked pix4d support if the Quadro issue has been resolved several times with no response.
Go to the nvidia website and manually search for your driver. It has a easy to use drop down to find the driver.
Arturo - thanks.
Austin - the HP system only supports 6 pin power supply so itâs not possible to install an 8 pin card, unless you know of a way to do it?
Austin , I would not use the Quadro for processing as the GTX 970 has more cuda cores which equal to a faster processing.
Not of the top of my head. But I do think you can install the GeForce card drivers on a Quadro Card just not the other way around.
Phillip there is a 6 pin to 8 pin adapter as long as your power supply can hold it.
Ya I know the 970 is quicker but would still be nice to be able to utilize both during processing.
Will try the new Quadro drivers and let you know.
I think the Z840 can handle the extra power.
So are you convinced the Quadro card is the issue?
Yes Quadro cards are a pain when it comes to programs and drivers. Motherboard would also be something to look at with bios update but it would hang in random parts not just step 3. If it was your processors you will have random reboots and system instability.
Which GeForce card is the latest and greatest to replace the K5200?
GeForce GTX 1080
Been looking for one for a few weeks.
For the K5200 wait for the new Titian has it will have more cuda cores and faster speeds . The 1080 has roughly the same cuda cores but it is faster. The new Titan with these price points will be great! Or dual 1080 
Well I upgraded the driver for the Quadro and its past the Load Point Cloud partâŠI still think all of this is down to buggy code. The Quadro card is designed for pro level rendering and processing - huge data sets. The fact that P4D doesnât harness that is not down to the card. Its the instruction set within the code of the application.
I am actually accessing my machine remotely via TeamViewer until Wednesday - so i am hesitant about remotely rebooting in case I canât back into it via TeamViewer and therefore âwastingâ processing days. I have 3 sections remaining to do of my 20,000 image survey. Plus I have to fix the .p4d file or at least wait for them to tell me how to do that. If they can, I can run step 3 only.
Have you noticed that the text of Stage 2 on the dialog window doesnât turn green even though its completed?
@Austin - where did you read about installing GeForce drivers on a Quadro card?
Quadro cards were design for reliability , not primarily focused on pure power. You are 100% right that Pix4d does not take advantage of this.
For the driver you have to install GeForce VBIOS on the card.
So if I install the VBIOS and then which GeForce driver? Will the system then treat it as a native GEForce card after?
