Even I am a bit surprised by the fps on SSE, i really thought it would be low on my PC.
Vessel: Protector
Enviroment: New York
Weather: Gentle breeze
Fps was 30 to 40 in Medium settings.
I also tried in High settings (same vessel, environment & weather) which gave me 23-49 fps, however the vessel was a bit 'jerky' on High settings.
I don't use overlocking or anything like that
