I installed Elementary OS Loki today and it doesnt feel smooth at all. It is very laggy. I know for a fact, that once I updated my drives on Ubuntu, which had the same problem, it was really smooth.
I am, however, unable to do that.
I have an AMD Radeon HD 5770 with 512 MB of GDDR5 memory.
I have no idea how to install the proper drivers. I tried many tutorials but none helped.
Any help is appreciated.
