That's a possibility however the Windows 10 32 bit PC has 3.1GB of RAM whereas the Windows 10 64 bit virtual machine (with no thumbnail problems) has 3.4GB so not a lot of difference. Could it be the fact that the PC is 32 bit be a factor

Peter, by today's standards of how programs use ram, you are really short in my humble opinion.
My machine has 16.0 and my wife's has 8.0 gigs of ram, and they are not new machines.

All this can be solved in a moment if Mike had one image file.
Try turning off Photo Shop or any other program that might be using memiry.

Since the problem is on my backup installation of QU and QI it's not of critical concern to me. I guess the vast majority of PC based QI and QU users are now 64 bit. 

Peter,
Try this:
Hold the Shift key down while you click on Analyze settings in the help menu.
See what the number are.
That is telling you how much ram QU has at its disposal

Thanks for your ongoing interest in this Fred!

Do the values represent free RAM?

As in the quote above, the numbers show how much RAM is available to Qimage to use right now.

Fred, was the QU memory screen capture you posted on your 16GB PC?

If so, why are the numbers identical to those on my 3.4GB (virtual) PC? Especially if the numbers represent "how much ram QU has at its disposal"?

Also, doesn't RAM extend to virtual/paging on disk if required?

Yes, the 16 gigs and 64 bit

Below I posted the same screen from wife's 32 bit machine with 4. gigs of Ram.
The numbers are not reflecting the ram in the machine, but what QU has available and what it needs to run based on its written parameters.
Right now, as written, approximate max size of a file that QU can open is around 1.2 gigs, as long as there is enough ram on hand that QU has all it can use.
The virtual paging is dependent on how the program is written.  I know that in many situations while developing QU, the sweating and hand wringing was due to finding the right balance between time to open an image vs impractical speed.
Anything more technical, have to refer to Mike.

Qimage is a 32 bit process and the maximum RAM that a 32 bit process can address is 2GB.  On a 64 bit operating system, the operating system can give every process the full 2GB of RAM so all 64 bit operating systems will give Qimage 2GB of RAM to work with.  On a 32 bit operating system, the operating system itself shares that same 2GB page size so it cannot give Qimage the full 2GB of RAM: it's closer to 1GB because the operating system itself can only address 2GB so it shares the same RAM space with programs.

64 bit Windows: has access to all your RAM so it can give all 32 bit apps their own unique 2GB "page" to work with
32 bit Windows: has access to 2GB of RAM at a time so can only give 32 bit apps what is left over of that 2GB (what the OS isn't using)

Hello Mike et al

Am interested to know if the updated fusion interpolation is or will be incorporated into Q1 Mac.

Also, are there any plans for poster mode be introduced into Q1 Mac?

I know I've mentioned this before (with some discussion, humor me), I continue to want to experiment with the 1200dpi printing option for the Canon Pro 1000. To me it's a pity that an option provided by Canon for that model printer is not offered in Q1 Mac (but is in QU).

I notice that the printing module in Capture One 11 on Mac has the 1200dpi option. However for me printing via Q1 Mac or QU PC is preferred. My main computer is a Mac and I prefer not to have to switch to PC for printing.

Regards

Peter

Hi Peter,

With Qimage One, we wanted a simple interface that produces optimal visual results without the user having to get into settings like "overdrive" or various resampling methods.  Honestly, we didn't even want users to have to contemplate the implications of changing settings like that in Qimage One.  Things like the 1200/1440 PPI overdrive are really not applicable to normal photo prints and that feature only comes into play for prints that might be examined under magnification such as possibly aerial photography or maybe something like microfilm.

Having said that, we have been looking into the possibility of a setting in Qimage One that would unlock some "super user" settings like overdrive and interpolation methods for the power users.  Stay tuned: we're alway improving the software!

Regards,
Mike
