I've got a Radeon HD7950 running with a recent catalyst driver. Here are my setting:
[opencl_init] opencl: 1 [opencl_init] opencl_library: '' [opencl_init] opencl_memory_requirement: 768 [opencl_init] opencl_memory_headroom: 300 [opencl_init] opencl_device_priority: '!GeForce GTS450,*/!Tahiti,*/Tahiti,*/Tahiti,*' [opencl_init] opencl_size_roundup: 16 [opencl_init] opencl_async_pixelpipe: 1 [opencl_init] opencl_synch_cache: 0 [opencl_init] opencl_number_event_handles: 25 [opencl_init] opencl_micro_nap: 0 [opencl_init] opencl_use_pinned_memory: 1 [opencl_init] opencl_use_cpu_devices: 0 [opencl_init] opencl_avoid_atomics: 0 [opencl_init] opencl_omit_whitebalance: 0 You may want to check if opencl_use_pinned_memory makes a difference when exporting huge images (cases where tiling plays a role). On my system the effect was huge (like 3 to 4 times faster export).
