I've had the R5 2600 for a few days, it's already a lot better than before, but Fortnite, for example, is still a little bit playable but not in the endgame and it doesn't look that smooth, I play at 1080p and everything on low can Maybe it's because the Kfa2 rtx 2060 is not so good or I did something wrong. I also clicked on oc in the msi afterburner to overclock but then I didn't know what I was doing and didn't know how to do it now
Your pc doesn't like the game like the rest of humanity.
No, the 2060 is well suited for this game. My buddy still has the predecessor of the R5, the 1600 and an RTX 2060. He also gambles on low and achieves very high FPS rates. The problem may even be the Fortnite servers, or your internet and not the PC.
I don't play Fortnite myself, but I keep hearing from my colleagues about stuttering because the internet is bad. Or the servers are the problem again. The graphics card is not to blame in this case, since you don't even load it properly when everything is low.
I also have the R5 2600 and I play a lot of current games with no problems.
Look at your ping in the game, it may also be that it is very high for a short time.
Always have a 10 ping
But that's really funny. It's hard to say if you can't test directly. I don't really know about Fortnite myself, I'm just surprised that you have problems.
