HI, so i plan to buy a Samsung Galaxy Tab S8 Ultra with 16gbs of ram. Is this enough to create hyper realistic drawings without creating any lag???? I heard the more layers you create, the more RAMs your tablet uses.

Here is an example:

Except i plan to use Clip Studio Paint instead of photoshop.

Any help is appreciated!
