After downloading the Echoes of Duviri Update there is a noticable performance drop, even thoug i had changed no quality settings
Depending on the mission it varies, but usually range around 50-80 fps where it was 100+ fps before.
System:
Intel Core i5 8600K
32GB RAM
GeForce GTX 1080
WQHD Resolution
Win 10
All settings maxed, using DX12 and 8x TAA
All drivers up to date and verified and optimized the download cache.
Temperatures of the system are okay (CPU 40° under load, GPU ~85°), other games run without issues.
After testing around some settings it seems this is caused by the SSAO Quality Setting - turning it down from high returns to the Pre-Echoes performance both in orbiter and in missions.
Orbiter, standing in the cockpit and looking down the ramp:
SSAO High: ~45fps
SSAO Medium: ~115fps
SSAO Low: 120+fps
Cambion Drift: Standing unter the archway leading out from the necralisk (next to the Necramechs):
SSAO High: ~59 FPS
SSAO Medium: ~95 FPS
SSAO Low: ~105 fps
