Capture One Pro 10.2 Unusably Slow (problem disappeared)

The v10.2 program's user interface is almost unusable. I takes around thirty seconds or more to respond to a single mouse click or keystroke. This is because the process is using near 100% of all twelve logical CPUs.

Sorry to hear about your issue. I have an identical configuration with the exception of a GTX 1070 rather than 680. Capture One 10.2 is very fast and has become my choice for processing my D810 images due to performance issues with Lightroom. The only time I've experienced performance issues with C1 it has been an Nvidia driver issue and an update to the latest version was the cure. You might take a look at your Windows Event Logs to see if anything unusual is going on. You might also try temporarily disabling any anti-virus or malware programs.

Edited to add:
Since Windows Task Manager shows the CPU and Memory usage of all applications, processes, and services it might be worthwhile to check if anything else it taking a lot of resources when 10.2 performance is slow. Using open CL or not? Try changing this preference.

Thank you, Luke. It is only C1's hogging CPU - not other processes - and I am using the latest nVidia drivers. I'll see if there is anything pertinent in the event log and report back. I have raised a support ticket.

openCL setting are set to auto. ("Capture One is using hardware acceleration").

C1 v10.2 is now regularly crashing. C1 catches the exception and emits the message - to elide and paraphrase - "Capture One has stopped responding" - within a bug-report dialog box.

I changed the CL preference to "Never" to no avail.

I can find nothing pertinent in the event logs. I don't (knowingly) use anti-virus and anti-malware scam-ware; though Microsoft does like silently to turn their "protection" on.

If you are using a catalog you might try creating a new one to see if that makes a difference. Failing that you could have a corrupted installation of 10.2. It would be worthwhile to run the Windows Memory Diagnostic. A memory problem can cause a variety of performance issues.

Capture One froze and locked-up the computer. After power-cycling and restarting Capture One it came up in trial mode; I had to re-enter my license code. Since then the program has been running normally. I unfortunately have no idea what caused this problem and why it went away, so I can't really say that it is "solved".

Could it be that it was busy (re)generating previews? Or setting up hardware acceleration?

No, because previews are generated quickly and h/w acceleration set-up is rapid too - when the program is running properly. The machine has twelve logical cores, 64GiB RAM and dual GPUs. When these two events take place there is always a progress pop-up anyway, which there wasn't.
