***382.05 nvidia driver fixes this, 60fps steady now.
Strange. I go from 144 fps looking straight in this room, to 27fps looking down.
*I see someone else pointed out this area as well.
if anyone wants to check it out, its in the powerplant section. You go down an elevator to get to this area
Everything is maxxed except AA is smaa 1x.
Figured it out.
Everything on low but Very high and High Shadow quality tanks the framerate in this particular area. I haven't had one drop until now. Medium shadow quality drops to 45. Low shadow quality is the only way I'm able to get 60fps while looking down in this room.
I have a 6700k and gtx 1080.
I do not have the latest nvidia drivers. I will check them out now.
*************Wow, did not expect drivers to fix this but it does. Everything max except AA like I said before, and steady 60fps looking down now.
And I spoke too soon, as I finished up the area, the framerate started getting erratic again.
