I’m currently having a problem with my 3080 on Apex

I installed a 3080 in my prebuilt pc that has a AMD Ryzen 5 5600G CPU in the drop ship I have about 18 to 22 Frames and then I land I’m running about 80 to 100 Frames but if look at the ground I’m getting 240. I have all the video setting at low and my monitor is set to 240 Refresh rate
