I started using Blender to learn 3D design. I'm using Blender 2.78. My problem is that when I'm in 3D editor, the editor skips frames. For example, if I want to extrude a finger out of the hand, it won't show me the extrusion until I've dragged it out quite far. Due to this I am unable to select various positions and sizes. This was not happening before. It started when my model got a little bit detailed. My specs are: GPU: Nvidia Geforce 940 MX. RAM: 8 GB. CPU: Intel Core i3 6100u 2.3GHz.
Can anyone please tell me how i can fix this? Thanks.
