Hi!
Just got a new monitor, LG34GP950. It’s my first ultrawide and was expecting an fps drop of around 15 fps when I switched from a 1440p AOC 32 inch 16:9 display. However, when playing Warzone I now get about 60-70fps (got ~140 before) and on RDR2 I can’t even maintain 60fps. The games occasionally freeze aswell, and lowering the graphical settings doesn’t seem to make a difference. I’ve even tried playing on my 65’ 4k tv where I get better performance than on my new LG monitor..

I have tried doing a clean install of my GPU drivers, did windows updates but the issue persist. Am using the DP cable that came with the box (it’s plugged into the GPU correctly). Please help.

specs:
CPU: i7-12700k
GPU: Rtx 3080 TI
MOBO: MSI ddr4 Mortar
Ram: hyperX 16GB
SSD: Samsung evo 1TB

2160x1440 = 3.110.400 pixels (2K)
3440x1440 = 4.953.600 pixels (2K ultrawide)
3840x2160 = 8.294.400 pixels (4K)

With 2K ultrawide, there are ~60% more pixels for GPU to render, over normal 2K and do you really think you can get away with only 10% FPS drop? :unsure:

TVs, usually, have low refresh rate, 30 Hz or 60 Hz. And when GPU refresh rate is matched to that refresh rate (e.g via G-Sync), GPU doesn't have to work harder. Only as much to provide 30 or 60 FPS.

However, when playing Warzone I now get about 60-70fps (got ~140 before)
Looks normal to me. Since GPU has to work 60% harder, your FPS is also effectively cut in half.
