When I load a vector with a large number of features into QGIS, the rendering time can become extremely slow. But when I look at my system resources, they all have plenty of excess capacity.
What is the bottleneck that makes the rendering take so long? Is it a question of system resources that for some reason are not being allocated to QGIS?
If it matters I'm currently using an Intel i7 quad core / 16gb ram / NVIDIA gaming GPU / Windows 10.
What I'm trying to figure out is whether it may be possible to speed things up by upgrading hardware?
