Hi! I'm playing on Ultra without AA and DoF:low. At 1080p I'm getting around 60-75 (vsync limit) FPS while switching to 1440p makes the game run at 25-40 FPS. I know that it's a higher resolution but I shouldn't loose that much (especially since higher resolution will make the game less CPU dependent).
Meanwhile MSI AB shows GPU usage jumps from 0% to 100%. I don't get consistently high GPU usage. Tried to set god rays to low or even off still the same:
OS: Windows 10 x64 latest
RAM: 16 GB DDR3
VGA: R9 Fury
Driver: Crimson 16.9.1 Hotfix + VSR for 1440p + Power Efficiency disabled
Game: latest version on steam
