WHAT DOES JAV MOSAIC MEAN?

Currently, I'm making use of i3-6100 with 16GB of memory as well as a Nvidia GTX 750 that only has 1GB of memory. Is there a means to regulate the parameter for small stop GPU? If not, what is the bare minimum memory demanded for your GPU?Also, taking away mosaics, should you don’t have the correct to do it, might get you in troubles with privacy
