I think I can understand what you are saying right here.
I used to have a 1050ti (4gb), and an i3-8100 plus the 8gb ram sticks, and I was just hovering around 50 to 65 fps on average (lowest possible settings 1080p).
I've heard a lot of people saying that Apex you can run on a lower end pc, but I'm not seeing these results with what I used to have which was definitely your average low budget "gaming" pc.
I'm not sure what was going on then, but I can tell you that Apex Legends is actually pretty demanding.
For those who read this, I would just like to point out if you're going to play Apex a lot, and if you are planning to buy a platform to play it on, either get a console or get a decent Desktop PC.
I would like to see some lower setting options.
