does anyone know whether last versions of QGIS (like last one, 3.6.0) make use of GPUs (either integrated or dedicated ones) in order to accomplish 2D tasks (rendering, zooming, panning...)? If it does, is GPU memory amount important for those tasks?


According to Docs, which You can find on Qgis Docs Page you can set setting relevant to CPU rendering. Docs don't mention GPU involved in rendering.
