Question about the performance test

I got a score of 1283 [same every time I ran it] but there's something that to me seems wrong.

My pc is an ok one - I have a ryzen 2700x at a stable/constant 4.1Ghz oc and a 2070Super that runs at 2100Mhz in games. Also 16Gb of ddr4 at 3400. It seemed that just 283 above the minimum of 1000 is very low for a game like this so I went and checked the fps and frametimes during the test using rtss and it turns out the game was sort of capped at 59 fps. While playing I have I think 120.

So is this normal or is it a glitch?
