I'm getting some woeful performance, mostly severe stuttering and large FPS drops when looking in certain directions. Full screen mode is pure stutter hell, I've had to use the borderless window mode to get anywhere near a consistent framerate, but even then I get very intense stutters when sprinting.

Graphics options do very little to help, even on the lowest settings I still get bad stutters when I sprint and even just walking. I've tried updating to the latest Nvidia driver and it hasn't helped, also tried all the usual stutter reducing tricks in my driver settings but nothing really helps.

None of my other games are having trouble, just Fallout 4.

I'm having the same problems using an AMD card, only probably worse, the game is unplayable.

AMD FX 8320 (3.5ghz)

Same here... I did try with different settings, no success

GTX 960

I5 4460

No problems here... Glorious 60fps solid even recording.

I'm glad to hear it. There is hope yet

OK. I was able to fix the stuttering performance issues I was having. I followed an excellent guide on the Stream forums for unlocking the frame rate.

Unfortunately, I don't have permission on the Bethesda forums to provide the link.

Essentially, you need to open the Fallout4Pref.ini file (do a start menu search) and change the line that reads iPresentInterval=1 to iPresentInterval=0

Then you need to make the .ini file read-only to get the changes to actually take hold. Do this by right clicking the file and selecting "properties" and checking

"read-only." Start Fallout 4. The problem should be fixed. Then exit Fo4 and go back to the Fallout4Pref.ini file and turn off read-only, the changes should now persist. (You

don't want to leave read-only on as it won't let you make any more changes to the preferences file through the game.)

Hope this helps.

I have a gtx 980 and i7860 8gb ram and 120gbssd. Running ultra settings at 1080p. No stutter or issues. Did you guys download the new nvidia driver for fallout that just came out? Otherwise the OP pc is better than mine and should run the game fine.

Everything maxed out I can't maintain solid 60 with sli on or off. Dips to 40 quiet often. (I know the game does not support sli yet)

Micro stuttering is also present,

Even with anti aliasing to best performance or best quality I can't maintain solid 60.

I personally think looking at the benchmark results that have been put out by nvidia, if a gtx 980ti is the only card the can maintain a steady 60fps at 1080p then they need to do some serious optimisation

Well, finally solved my performances issues.

Tried so many things it's hard to say exactly what worked but my best guess is what i did last: uninstall/reinstall directx and vcredist from the _CommonRedist folder (can't think why i didn't start there).

This may be a silly question but how exactly did you uninstall those files? I've been trying to resolve this frame rate issue for 2 days now.

Sadly can't provide any solution as I've tried almost everything. However I can confirm I'm suffering this as well. I can load into an area and my frames are 35-60, but over time frames stop to drop down to 15 to 25. I see this is a minor issue compared to the Radeon's problem where he's lowed to 8 frames. I consider this issue to be just as bad, I mean you can't us to enjoy exploring whenever frames are ridiculously unstable. Please Bethesda fix this!!!

My game stutters in random places while maintaining 60fps most of the time. If I go into Corvega Plant, or Metford Memorial Hospital, or any interior with a light coming through the roof/fog effects tanks me to 50-55 fps. Shame as it really runs beautifully when it's not in one of these problem areas. For instance, Diamond City I get the smoothest, buttery 60fps but if I face a certain direction it goes downhill.

Are you saying this issue takes you down to 50 frames?

Just keep an eye on your fps. If over 100-110, you may stuck on a terminal. !!!

I appreciate the help, but I've more or less tried everything. Reporting this bug is a last resort for me now sadly....

Could you please explain the steps to do this?

Shadow visibility range is the most taxing setting in this game.

For me lowering it to medium caused to FPS increase by 20 in some high density areas (mostly cities).

I tried every stutter fix. As far as I can tell the game suffers from two kinds of stutter on my system, bad frame pacing and asset loading stutters. Ipresentinterval only fixes irregular frame pacing in fullscreen mode, it doesn't stop the loading stutters for me. Windowed mode does not have the irregular frame pacing but absolutely does have loading stutters. iFPSClamp fixes the loading stutters almost entirely BUT it also happens to break certain game events.

You're absolutely right. Having shadows on anything above medium causes crazy framerate dips, I could have all other options set to low and the dips still happen. I've come to the conclusion that this port slid from Bethesda's bowels with a bare minimum of effort, there's just far too many interface and performance issues to ignore.

i see many posts from people with higher level GPUs than me getting these problems with using ingame consoles and getting huge fps dips when looking in certain directions. so much so that they claim it is "unplayable". so many of them claiming it just isn't optimized, but this game has pretty high recommended settings compared to a lot of other newer games. obviously Bethesda knew it was going to take a bit to run it at higher resolutions with the highest settings. when you can see details and shadows and real landmarks miles away it takes quite a bit of processing power plus fights going on blocks away with explosions +. i'm sure those directional fps dips are just that; certain directions will have more [censored] going on in the distance whether you can see it through the buildings or not.

it does seem odd that it's so hard for many with super setups and high overclocks to keep the frame rates above 60 consistantly though when it's very easy to sit right there. i imagine that is a design flaw where the game is "meant" to max out at 60.

i get a pretty smooth 50-60fps in all areas. through 20-30 hours of play i've gotten a few slight stutters but nothing noteworthy or consistant. randomly dipping 10fps in any game is not a problem, it is almost completely unnoticable unless you're just staring at a frame counter. if you're playing at 120fps and it's dipping to 50-60 then I could see that being a major annoyance though.

for me, keeping this frame rate at 1440p shadows and godrays need to be set at medium. but at 1080p everything is maxed out.

Firstly, you said you run from 50-60fps in all areas. That's not acceptable. Dropping to even 55fps in this game is highly noticeable and no I'm not staring at a frame counter. I guess my eyesight is pickier. It should be 60fps at all times with my rig and it's not which is absolutely unacceptable. Also, if I spent $800 on a video card like you, I'd at least expect this visually unimpressive game to run.

- After the AMD driver update it ran at about 25 fps but still got a few fps drops and freezing (after walking far enough for some stuff to load in).

- I overclocked my GPU with CCC to it's maximum settings (GPU-1050MHz, Memory-1450MHz, 70% fan speed @ 50 Degrees) which helped a bunch. I will also note that the game had my gpu and memory speed running at full capacity, staying at around 80% load. This is a considerable change post driver update, previously at 30% load with lower gpu/memory speeds.

- This is where I got the biggest improvement. I decided to push my CPU speeds a little bit to see if that extra power would create less of a bottleneck (I am guessing at a bottleneck due to the game running at 97-100% CPU on both cores and 80% GPU(post patch)) and after playing around for a few hours am sitting stable at 3.9GHz up from 3.3GHz, hurray! I loaded up the game and huzza, everything loads up faster, I get a stable 25-30 frames no matter where I go with the occasional drop to 10-15fps for a few seconds and MSI Afterburner is showing 90% CPU load and 90% GPU average (seems to have balanced out).

- I'd also like to note that if I leave the game running, (pressing escape or tab so it's paused) and leave for a little while, when I come back I get SEVERE fps drops, longer freezing and mouse stutter. This was pre-overclocking and post-driver update. The same thing happened (good fps to severe freezing and stutter) if I would enter a building and come back out (good FPS outside, good FPS inside. Go back outside, [censored] FPS).

- Applying these lines into the Fallout.ini folder under [General] helped me a lot with loading, load-in stutter and quick travel loading times:

(This was found from a reddit post, link here: //www.reddit.com/r/fo4/comments/3sx5w2/these_few_ini_lines_made_a_huge_difference_in_my/ (I haven't experimented with the updated lines in the OP))

I'm not about to get too deep into speculation because I know very little about the game engine and how it interacts with my system but from my own experimentation it seems like there is a memory leak and optimization issues (further than what was solved with the AMD patch, I feel for the Intel GPU users out there). I hope this was detailed enough for someone more knowledgeable than myself to get a general idea of what is happening or helps another AMD user

r3syfl0 said that he solved this. Can someone please find a solution on how to "uninstall/reinstall directx and vcredist from the _CommonRedist" so that we too can test this please?

Ok, I had the luxury of being able to get a clean win10 install.

I re-downloaded fallout 4 on steam and ran it. The FPS is at 60 stable on ultra with god rays enabled. I checked my nvidia driver, I have version 353.54. The newest is 358.91.

Sure, everything else is new and the problem could have been somewhere else. Would anyone care to have more information since I have both OS bootable? Could my system help solve the bug?

Advice: Instal an older driver until they fix the new one.

except I spent ~$359. where have you seen an $800 8GB 290X? think you're shopping at the wrong spots. and the game does run fine.

obviously you don't know what fps you're dropping to if you're not watching a frame counter. so how can you say you notice it dropping from 60 to 55? you may be dropping to 30 or less like some others have stated, and that would be totally noticable unlike only dropping 5-10fps.

but, the new Catalyst beta package has stopped even most of those small drops for me. it sits at an easy 60fps almost all of the time now. the only drops I've found at all since the update is when I am on the roof of very tall buildings. it hit between 41-45fps three times now when the buildings were tall enough, but if it's only 3 floors or less it still sits at 60. and it isn't a flat drop, like others said it depends on which direction I'm facing. even that is not enough to make a game unplayable or bothersome.

strange that distance from the ground would cause an issue at all but it could very well be that the higher you go the more you can see off in the distance.

Um..buddy..I've had RTSS running the entire time and have been actively monitoring the FPS. Good talk, though. I never go below 30. 60-50 is very noticeable and if you don't notice it, edited I'm sorry. Hopefully nVIDIA releases a new driver soon.

Excuse me for speaking frankly, I don't care for politically correct, petty forum conduct. Once the game works I will never be seen here again.
