i use Digi BB100 and tried playing online PS3 games back in Nov 2016.
So far so good. Almost everynight playing Battlefield 3 no problem.
now i got my PS4 pro in Jan this year, playing Battlefield 1 is smooth. but sometimes i do face some laggy-ness but on rare occasions.
Played Doom online with Europe players, speed not bad but got some lag here and there but it's playable.
MGS5 online (MGO3) no problem with speed.
other games i dunno because i don't have them.
but one thing for sure, having 4G LTE broadband does have it limitation especially when it comes to downloading large games over PSN which can cost around 20-30 GB in size. My digi BB100 only offers total of 40GB of data, if i use it to download games, then i will not be able to use for my daily usage.
For example, the Doom latest update was almost 30GB and i was forced to bring to my office to download the update nearly 2hours.
Digi BB100 = RM100
4G LTE mobile router with sim card enabled = ~RM450
the 4G router is quite expensive but it's a good investment in the long run.
TP Link, Dlink got superb 4G LTE router, just search for them on the net.
i am forced to use mobile broadband as no unifi/streamyx at my taman yet.
as always, try using prepaid at your place first to see how fast is the speed.
time to change to Digi 150 Infinite.
