I'm experiencing a dramatic framerate drop each time when entering the dungeon in Stormwall Gorge. All the overworld areas and other interiors have run at a silky smooth 60fps.

 

The framerate drop also appears to affect the speed of the screen scrolling - is scrolling speed tied to frame rate? If so, this needs to be corrected.

 

My system:

 

intel i5-2500k @ 3.3 GHz

8 GB RAM

ATi Radeon HD 6950 2 GB

Windows 8.1

I can confirm that. Everything is exactly as you've written.

 

AMD 8320 @ 4,4 GHz

8 GB RAM

GTX 660

Linux Mint 17 64-bit

I just checked with RadeonPro and the framerate drops from smooth 60 down to 27ish. There might be some visual effect causing this I think.

Same problem occurs on my laptop:

 

AMD A10-5750M 2.5 GHz

12 GB RAM

AMD Radeon HD 8650G + 8670M Dual Graphics

Windows 8.1 (64-bit)

I have the same problem

 

Intel I5 3.4 GHz

16 GB Ram

AMD Radeon HD 7800 series
