Old graphics are using double dedicated memory?

Hi!
One or Two years ago my app used around 1GB of dedicated memory from GPU, these last days I was surprised when I notice that my app uses now 2.2GB of dedicated memory … but all resources and buffers are the same!

In fact, now I did a test, I included a big buffer on the startup of my app, and the Vram consumption was the same! What I am missing?

Also, I am surprised that when compiling shaders it takes 300Mb Vram, that is strange :confused:

I am using GTX1060 with the latest drivers.
