i think my 2080ti isn't getting the good fps.
In Escape from Tarkov I average around 50fps with everything on medium/low at 1440p, benchmark videos I've seen average 90fps with everything on Ultra.
In Assassin's Creed Odyssey I average 45fps everything on Ultra when I see benchmarks avg about 80-90fps in 1440p.
And other games as well.
I'm wondering why I can't hit those frames with my gpu.
NVIDIA Driver Version: 445.75 grd
CPU: i7-8750H
RAM: 24GB
Any tips?
