This is hardly a good reply. Of course OpenCL support is added through the driver, hardware simply executes opcodes. The support was added after all, so people still expect to be able to use it. A discussion will make people understand so it solves any suspicions of bias. My understanding is that certain features or extensions either run on software or are missing. If people can know them though, and know their importance they can be more understanding. And more importantly, they can stop feeling that the developers are biased towards NVIDIA. Anyways, here are some references: http://developer.amd.com/sdks/AMDAPPSDK/pages/DriverCompatibility.aspx, where you can clearly see that GPUs have beta OpenCL support (unfortunately couldn't find the conformance results) http://developer.amd.com/sdks/AMDAPPSDK/assets/AMD_Accelerated_Parallel_Processing_OpenCL_Programming_Guide.pdf, where, if you check under AppendixD the lowest GPUs mentioned are series 5. http://developer.amd.com/sdks/AMDAPPSDK/assets/AMD_APP_SDK_Getting_Started_Guide_v2.4.pdf check section 5 supported devices, where all the features supported are enumerated. _______________________________________________ Bf-committers mailing list [email protected] http://lists.blender.org/mailman/listinfo/bf-committers
