I think this is more important than other features because when rendering long animations in high res or high quality, it can take quite a lot of time to render. I rendered my 18 seconds long animation in 1080p HQ 60 FPS and it took about 4-5 minutes to complete, but Mine Imator barely utilized the GPU in the rendering process. IMO the process could be sped up tremendously by using the dedicated GPU to render.
