This has been fixed in Autopano Video Pro 1.5 Final.
When rendering the fisheye projection to frames, I've noticed that only certain resolution sizes are allowed to render on the GPU. The others are kicked to CPU for rendering. Happens consistently for any AVP project I try and render. --- GPU render as expected: 4000x4000 --- kicked to CPU render: 5004x5004 --- kicked to CPU render: 5000x5000 --- kicked to CPU render: 4096x4096
This is specific to fisheye projection, as spherical projection GPU rendering has no problem with any resolution selection. --- GPU render as expected: 8188x4094 --- GPU render as expected: 8000x4000
System Specs: Windows 7 x64 Intel i7 3.5GHz 8-core GeForce GTX 770 16GB RAM

Issue 3392 opened. This is really strange as we won't switch if you asked for gpu rendering, we do gpu rendering. But perhaps, this projection is killing the performance which would explains that it looks like CPU.
When trying to render using the GPU, we do some tests to ensure the panorama will be safetly rendered. We check the capabilities of GPU, the rendering settings, etc....
In some cases, the software could decide to switch to CPU processing. It is the behavior you are reporting. When reviewing this piece of the software, we found a bug that will be fixed in the final version of Autopano Video 1.5.
