Summary OpenCL (GPU) Support in Capture One
Problem What does OpenCL do and how do I use it in Capture One?
Solution

Optimal speed through OpenCL/GPU 

OpenCL is an open standard defining how to interface and utilize many processing cores with graphics cards (GPU), multiprocessor CPUs and RAM. OpenCL is short for Open Compute Language. As of June 2013, four major companies have developed drivers for OpenCL: NVidia, AMD, Intel and Apple.

For Mac OS X these drivers are part of the Operating System, where the drivers have to be installed manually under Windows.
The driver itself performs runtime compilation dedicated to the graphics card in the machine at hand. Only relatively new GPU cards have enough "compute power" to be utilized effectively.

Open CL will dedicate memory to several actions in Capture One.
The following outlines the softwares demand;
• Preview Update with different settings, styles etc: RAM
• Sorting/Rating: CPU cores and SSD speed
• Fit Image to Screen: GPU cores
• Process time: GPU processing units and CPU's and RAM


How to enable - what to expect

Hardware Acceleration is disabled by default, and you have to turn the preferences to AUTO to start testing your hardware for compatibility
Much faster processing of files.
Overall Performance Improvement with suggested hardware



Windows driver requirements

• For AMD/ATI graphics: AMD Stream 2.2, Catalyst 12.10 or higher Download here pick: AMD Catalyst™ Accelerated Parallel Processing (APP) Technology Edition
• For Nvidia graphics: NVidia Display driver version 306.97 or higher Download here pick "download".

Limitation in functionality

Certain Capture One settings will bypass the use of OpenCL and use the normal processing pipeline. These currently include:
• Use of Spot Removal


In case of problems using OpenCL

• Set OpenCL to Never in the Capture One preferences

How to completely disable OpenCL, in case of a crash at startup 

• Windows: run the script DONOT_useopencl.reg and restart Capture One (the download also contains a restore script to re-enable OpenCL useopencl.reg) Download here
• Mac: Run this script “ToggleOpenCL.app” - disable OpenCL and restart Capture OneDownload here
