I have two questions
1-What type of internet speed do you recommend and what type of tablet should I have so that with the last update the images are fast and in the game configuration I put all the images up and not slow and so it looks very sharp ?
2-Or is it just telling my internet operator to increase my speed?
Honestly, it might be trial and error until you search for the right tablet that fits you.
My wifi is going about 13-14 mbps for download and just short of 5 mbps for upload. It works well.
As long as your wifi download / upload speed is around mine (13 / 5) you’re fine.
