Flowblade won't utilise the full GPU for rendering

[Disaster2life]

Finally got some time to work on something, and GPU acceleration seems to be "minimal", I know the Position Scale (and somewhat less so but still) Position Scale Rotate filter rely heavily on the CPU, and my timeline mostly consisted of the Position Scale Rotate and Crop filters, so I thought to mention how little the GPU is utilised for rendering that, heres a screenshot I took from intel_gpu_top
