Hi guys,

After experiencing fps drops from 80fps to 30fps in totally random situations. I decided to investigate. I have found an issue (with 310.90 and 314.22) with possibly Nvidia only?

Anyway, with Ultra dynamic shadows, these random drops occur, without, FPS stays permanently high and solid.

Comparison:

With ULTRA

Very High (one down from Ultra)

The only difference I see, is the window. I am going to test outside, but honestly, with vsync on, constant fps of 60 without the ultra setting. With, it would drop to a solid 30 or go between, but never below 30???

Just thought I would let you know as I don't think I'm the only one suffering with this...
 
D:\Program Files (x86)\Steam\SteamApps\common\BioShock Infinite\Engine\Config\BaseEngine
Scroll Down To [SystemSettings]
VsyncTo60WhenUnder30=False Change to VsyncTo60WhenUnder30=True

Save and close and Right click BaseEngine and set to read only.

Tested on known part where frame rate hits 30FPS now its a solid 60fps :D

Grats to Shankly! This works a treat.
 
Glad I was some Help :D

Sadly mate, you was wrong :(

But helped a lot! It's this file you want to change. The one you suggested does not effect ingame other than reset the options. It's the related windows user config file. Still the same line you pulled though! So couldn't have been done without you mate:

C:\Users\Fresh\Documents\My Games\BioShock Infinite\XGame\Config

You want to change the XEngine.ini
