Alright, so I have not used Linux Ubuntu since probably 14.10, but I wanted to come back and was tired of Windows consistent crash and bugs. I like playing games on my PC, I have Wine and PlayonLinux. I am not as literate of the Linux world as I used to be. I don't want to ever switch back, but I am not sure how to get things rolling on here. This is the specs for my laptop.
RAM: 4GiB(3.8 usable)
Processor: Intel® Core™ i3-5005U CPU @ 2.00GHz × 4
Graphics: Intel® HD Graphics 5500 (Broadwell GT2)
I am running on 64bit Ubuntu. I tried installing Star Wars the Old Republic, but it keeps saying it can only run one instance at a time. Any feedback, tips, would be greatly appreciated. I am running Ubuntu 16.04.
