I had the same problem there. There are a few zones which make the FPS drop heavily. I thought I was good with my settings because I did the tweaks in some forest places instead of the castle zone.
In the end, I think I am dropping "high" 1080p for "medium" forced to 900p. I am using the following to get 75 FPS in most places, and the occasional drop to 30 FPS in computationally demanding scenes:
Code:
:/display
vsync false
:/render/medium
msaa_sample_count 1
render_width 1600
render_height 900
To get a fluid game, I am going to force the FPS to 30 with RTSS, so that I don't notice when the framerate drops from 75 to 30 FPS.
NB: With "msaa_sample_count 2", the game runs at 60 FPS but can drop to 20, which is not good.
