GPU VRAM and other applications

Substance Painter is not alone when working with the GPU, other applications can do the same. The Unreal Engine 4 for example will require something like 70% or even 80% of the GPU memory. A solution to ensure good performance while keeping theses applications is to be sure Substance Painter is launched first in order to request its own VRAM allocation. Still, some software can require some parts of the VRAM dynamically and can still be in conflict with Substance Painter even if it was launched after.
