I just built a new PC and a 2GB Vid Card seems to be on the small side. If you go on the Alibre website, it even states:
Video Cards
Most modern cards made in the last 3-4 years should support DirectX 11. If your card does not support DirectX 11, you can use a compatibility mode but some features will not be available to you. It is strongly recommended to use a graphics card that supports DirectX 11.
4K Displays
If you use a 4K display (typically 3840x2160 or similar), 4 GB of Video RAM (VRAM) on your video card will likely be required, based on your designs. 6 GB of VRAM is recommended for 4K displays. If you do not have enough VRAM, you may experience sluggish visual performance during screen updates, for example during model rotation.
