Hi there,

I'm experiencing low FPS in some areas of the game without any valid reason, and changing settings don't change anything.

For example, in the last room of the Corvega Assembly Plant (the one where you kill Jared), if I look towards certain spots I always get 17 FPS no matter what.

Even if I change ALL the settings to the minimum and best performance options available, I still get the same 17 FPS on that area when looking towards the lights. If I crank it up to the maximum settings my PC can run I get the same result: 17 FPS. Always running full HD only.

It seems to be related to lightning or maybe to mist/fog. But changing lightning and shadows options does nothing at all to improve performance, it just make the game uglier.

Here is my system:
Core i5 2500k running on stock speed
8GB DDR3 1600 Geil Enhance Corsa
Sapphire HD6950 Flex 2GB
Windows 7 64 bits

I've already updated the video card drivers, defragged the disk and rebooted the PC and nothing changed.

This is just a shame for a Fallout game. The previous games were much better optimized. I could even run Fallout 3 on medium settings in my old Pentium 4 Northwood with my old faithful Radeon X800 XT PE. This seems to me just an awfully done port from consoles to PC.

Does anyone here have a solution to that?

No one?

I'm having the same issues. I've run every test I could, even more advanced tweaks in the ini files, yet nothing seems to change it.

i5 3570k

GTX 660

8GB DDR3

gtx 780 i5 4670k 16GB ram and on ssd... got frames as low as 7fps outdoors.... what a crock of...

Core 2 Duo E8600, Radeon HD 7800 (15.11 Beta Drivers), 8GB Ram

100% cpu use (goes to about 70-80% if I turn off grass using TG in console but goes up when I'm moving around), 40% gpu which sometimes spikes to 90%

6000mbs of ram is being used as well

Indoors: 60fps, 30fps in big firefights

Outdoors: 30 rural, 15-20 urban. Drops to 9fps and stutters when walking around and moving mouse.

I've applied all the setting tweaks and fixes currently available. Hope this info helps and we get a patch soon....

Hi!!

Have same problem!

-AMD FX Series FX-9590 4.7Ghz 8X - Procesador + Corsair Hydro Series H110i GT - Cooler

-MSI Geforce GTX 980 GAMING 4G TwinFrozr V 4GDD5 OC

-MSI 990FXA-GD80 AM3+ AMD 990FX 6 x SATA 6Gb/s USB 3.0 ATX AMD Motherboard

-HyperX FURY DDR3 Memory 2x8GB

-Corsair RM850 850W 80 Plus Gold Modular

I play beetwen 54 - 60 fps with all graphics on ultra, but in city my fps drop wildly to 24 fps.

What do you think about? I think some people with nice pc's have same problem...can be?

Thanks for your time.

The game definitely has optimisation issues, especially for AMD products and the Geforce 9 series. Expect drivers and gamesas patches alike to get it to where it needs to be.

I hope so

Yes AMD users haven't yet received a driver release from AMD. Hopefully they improve things. Cortega plant is a place for frame drops.

The Shadow setting is hard on frames. ALso play with the sliders (generally actors and grass are hardest hitting). DUring rainstorms, rain occlusion. You can also try ss reflections. ALso godrays.

I've already tried lowering ALL the settings to minimum/off and nothing changed. I got the exact same FPS on some areas. =/

Same here. Give it some time.

Do any of you have FO4 installed on a solid state drive? I have noticed that when changing cells (or looking in a particularly graphically dense direction) that the game spends a lot of time loading graphics items (textures, shadows, etc...). This has little to do with your GPU speed /GPU RAM and more to do with hard drive read speed. I've been told running the game on an SSD can resolve this issue to a satisfactory degree, though I have yet to buy an SSD and try it myself.

I have a fx 8350, gtx 980, 8gb ram gskil 1600, outside Corvega Assemby Plant i have like drop from 60 to 30 ....
The only thing that it seem to keep me always in the +55fps line is the Shadow Distance in medium.
Im acctually tweaking this in the .ini files...
When you set "high Shadow Distance" this values "fDirShadowDistance" and "fShadowDistance" get to 14000 when you set "Medium Shadow Distance" those values get to 3000 ... a big big jump... so y estar to test changin manually to get the best performance/quality balance.
Maybe yo can try it ... remeber always when you change the value change file to "read only"
(My english is no that good so forgive the errors )

I appreciate that you are trying to max your frame rate at 60 fps everywhere and a rate of 30 is an issue for you. But, I would just like to point out that the human eye only needs about 30 fps to view smooth motion (movies are 24 fps). Any more is actually superfluous. I think the people in this thread are experiencing frame rates under 30 at specific locations that are independent of GPU capabilities and more concerned with load times (but I could be wrong). There are many more threads that deal directly with GPU tweaking, though some of the people in this thread may be in need of some tweaks.

If your issues are based on a frame rate under 60, I suggest turning off FRAPS or whatever other frame rate app you are using and just play the game. If it looks good to you, why care if your frame rate is 35 or 55? Again, your eye can't tell the difference anyway.

I have the same exact issue on a GTX 970 and a i5 4590. Bethesda support has been of no help to me. Some areas of the game are simply unplayable, hope this gets patched very soon.

Tbh i can perceive when a game is running at 30fps or 60 fps... and i can clearly see the jump off 30 fps when it suddenly happens ... i dont know if im special.. or just a "Fps Psycotic Ryder Boss" but i can see the diference.
Im having the same issue in the area around Corvega Assembly Plant and i running the game in a ssd so .. i think this drops maybe gpu/ cpu optimisation issue becouse chequing the % use of mi cpu and gpu .. clock ... memory ... the game is not using more than a 60% (Again sorry my bad english)

Have you tried both fullscreen and borderless windowed? When you do use borderless windowed make sure desktop composition/aero is enabled.

I was having severe troubles with stuttering and low fps despite settings and @ 1680x1050 resolution. I switched to borderless windowed and it now works flawlessly with max settings including god rays at the same resolution.

My setup is an i5-3570k, 8GB RAM, GTX 970, Windows 7.

That guy's trolling, just ignore him. This is a pc forum and nobody accepts 30 fps or under unless you're slow in the head.

Calling me slow in the head sounds a lot more like trolling than the genuine help I offered - which is factually, scientifically and physically accurate. Look it up yourself, the facts are out there. While the eye can discern flashes up to about 200 fps, the fluidity of image motion detection tops out around 30 fps. Though the number is different for different people. One can train their brains to perceive motion at higher frame rates than the typical 30, but still, fluidity is fluidity. I'm not trying to be rude, but it is my assertion that frame rates above 30 are more of a *want* than a *need*. Since the real world is purely fluid with an infinite frame rate, so to speak, your brain already fills in any missing pieces. This is true at about 18 fps and 1000 fps - because actual human perception isn't measured in frame rates - there are no frames. Once you've obtained perceived fluid motion, how can that motion be *more* fluid? What people might confuse is not that one frame rate is more fluid than another (above 30), but what your brain is used to. Another words, if you have been watching a monitor with a 60Hz refresh rate and then watch one with a 30 Hz refresh rate, your brain will notice the difference, though it won't be any less fluid. Watch the 30 Hz screen for long enough, and the 60Hz screen will look wrong to you too. There is a reason that monitors are set for 60 Hz typically and that's because receiving page files at half the monitors refresh rate will still rend at 30fps - which is fluid enough to the human eye.

Sorry for going off-topic, That is the last I shall say on the topic. Please refrain from further insults.

And to Null_Code: No worries about your English skills mate. I'm sure my language skills are far worse in your native tongue.

I've got the same issues around downtown boston, between Swan and trinity tower. Dropped to 18 frames on ultra and 47 frames on low. I'm on an i7 4790k, 980ti, 16gb ram, and on an ssd.

I have no idea where you got this information, but it's wrong. The human eye needs about 16 frame before it cannot distinguish between frames. However, the difference between how smooth something looks is distinguishable. 30 frames is not the limit how fluid something looks.

Film is made of 24 frames because of a natural motion blur created by the camera. 48 fps film looks to lifelike. It's to smooth, and makes actors look to fake. The subtle motions are not masked at higher framerates in film. Which is why camcorders at 60 look weird when people try to act. Video games do not have that natural blur.

You're so full of crap it's kind of amusing. OP, I hope they fix the issue soon. I have it in the strangest of places while being able to run 60fps in others where the slowdown should theoretically occur, but does not.

ya no thanks if i wanted 30 fps i would have bought console, and yes i can tell the difference

Gtx 780

i7 4790K

8GB RAM

Same problem here, although not as severe as yours. When I look at certain spots the fps suddenly drops from 60 to 40 and sometimes even as low as 25. I've did some research though, and I managed to find out it has nothing to do with any of our specs. Just plain old lazy Bethesda not optimizing their games properly. It's not hard to see the game isn't optimized if your CPU and GPU usage decrease when the fps drop occurs.

I guess we will have to wait for a patch from Beth, or ( which I have more faith in) a patch made by the modders which will probably be implemented in a later patch by Bethesda. It's like the "looking down from Dragonsreach" fiasco from Skyrim all over again. I guess Bethesda never learns.

enter: Skyboost

or in this case it may be called BostonBoost, lol

AMD just released a new driver with FO4 optimizations. For AMD users.
