I recently bought a laptop with an RTX 2060 gpu, and before I was using a desktop with a GTX 980-Ti, according to benchmarks these cards are neck to neck in performance. With the 2060 sometimes coming out on top even, the same applies to the mobile version.
On my 980-Ti I ran overwatch at 50-60fps on a 4k screen with medium settings, on my 2060 I am running overwatch at 60fps on a 1080p screen on low settings. This is more than 4x slower than it should be, compared to what I was getting on my desktop.
Any ideas why that could be happening and how to fix it?
