Hi Sebastian, sorry, but darktable won't support that. A sane OpenCL setup for darktable to run reliably requires 1GB+ of graphics memory. That's the default setting which darktable tests on startup. Even going as low as 512MB is calling for problems. Please understand that we as developers need to take care that OpenCL related noise doesn't get too heavy. The enormous diversity of OpenCL setups is already a big burden for us to help people. If we would now be faced with additional issues - even related to setups where we knew upfront they'd fail - we would drown. So these built-in limits are also a kind of self-defense :) Ulrich ------------------------------------------------------------------------------ LogMeIn Rescue: Anywhere, Anytime Remote support for IT.
