i7 7700k overclocked to 4.8 Ghz (hyperthreading enabled, without it I get even lower FPS)
16 GB 2666 mhz RAM with XMP enabled
EVGA GTX 1080 TI SC2 Gaming overclocked
Gigabyte Aorus Z270X Gaming 5 motherboard
2560x1440p 144hz G-sync monitor
So I'm getting drops sometimes below 60, average FPS is around 70-80. This is on ultra settings. I consider this very low with these kind of specs. With DX11 it is even lower, if I enable Future Frame Rendering then I get the same FPS as if I was running it with DX12, so I'm running the game with DX12 and FFR turned off so that I do not get any imput lag.
The BIOS is up to date, as well as the OS (Windows 10 pro 64-bit version 1809), and the nvidia drivers. From this point on I have basically run out of options, nobody knows anything, I've been asking for help from everyone. Is there anything I can do?
