According to this http://developer.download.nvidia.com/assets/tools/files/optix/3.0.1/NVIDIA-OptiX-SDK-3.0.1-OptiX_Release_Notes.pdf OptiX out-of-core rendering is not supported for nVidia GT series.
The full name of 690 is “GeForce GTX 690”.
So, does the GT series include GTX 690 or does it not ?
p.s. After all, how is it possible that it is not supported for the GT series at all ? I don’t see a single major feature, that is supported on the Quadro series (for example k6000) and not on the GT (for example GTX 690) and will cause out-of-core to not be supported … ? Or GT stands for Tesla architecture (like GF and GK). It is not clear for me at all. Shouldn’t that be bind to the actual architecture (Fermi, Kepler, etc …). Will be happy for a any clue on that.
Never mind, this https://devtalk.nvidia.com/default/topic/662159/optix/paging-not-active/ solves it.
nVidia 690 should be support. However, loading huge .hdr file is causing a crash (C++ badalloc, not CUDA driver api error) on my side, but I will post another topic about that.
