Lighting indoors causes game to slow down!
Hey people,

So I'm trying to enjoy Fallout 4 which is a little difficult due to a technical issue I have. Summarized, it's this: indoors light sources cause my FPS to drop down to ~45ish which in turn causes the whole game to slow down! I'm talking everything from controls to camera to animations just slowing down. However, the stupid thing is: this only seems to happen indoors.

At first I noticed it in the Vault 111 entrance and I kinda hoped it'd be only that location. Outdoors, I can walk around with an FPS of 50 - 60. Then I entered the Museum of Freedom and bam everything slowed down again.

I've tried every solution I could find by googling and so far nothing has helped.

Does anyone have any advice? I'm running everything on either Medium or Low.

My specs: (Lenovo Ideapad Y50-70)
OS: Windows 10 64-bit
CPU: Intel Core i7 @ 2.60 GHz
RAM: 8.00GB @ 798MHz
Graphics Card: Nvidia Geforce GTX 960M

Thanks in advance for any and all help!

Drop your godrays setting to minimum (or even off) and shadow quality down a notch or two...

You'll notice very little difference aesthetically, but should get a noticeable bump in performance...

I've tried that. My shadow quality is already on Low. My Godrays option is on low as well. I keep trying to turn that off, but it's always changed back to Low for some reason. :/

EDIT: Yeah, I can turn it off, then close the launcher and it'll hop back on Low. However, if I change it to Ultra, close the launcher, it'll stay on Ultra. o.O

EDIT2: The Fallout Config tool says it's off.

So for anyone that stumbles upon this thread with the same issue, I've found a partial solution:

While trying other methods, I wrote iFPSClamp=60 in my Fallout4.ini. What this does, though, is slow down gamespeed when it comes under 60, and up when it goes above 60.

So I set that to 30 instead, and capped my FO4 to 30 fps so it's at least stable and playable. No fix for the FPS drops though, sadly. :/
