I have 1060 i7 still lagging on peekI would change the rating of the skin changer, sometimes it can cause crashes, also you can't change already added skin (personally my quibble).
As for optimization, I agree, it's terrible. But I noticed that it directly depends on the configuration of the computer. Many have drawdowns in fps, at the peak. However, I and some other people I know do not have this problem. I have 1050 ti and I7-7700k I have no problems with the fps. I also tested with a friend, he has a 1650 and an I5, so he had a fairly small fps and strong drawdowns at the peak.
Loader - there are frequent problems, but however I like it because of my weak Internet, the loader loads the cheat very quickly, about 20 seconds to launch to the csgo main menu, when I wait about 3 minutes in neverlose
