Cannot for the life of me figure this one out. I cannot seem to get Fallout 4 at 60fps at 4K with 980Ti SLI. That hardware (inc. 4790K @ 4.5Ghz) should be able to hold 60 in this game even at 4K - it's hardly an incredible looking game. And I've seen plenty of evidence 60fps is quite possible with this rig at 4K but for everything I've tried, including all the bits with Nvidia Inspector, I cannot seem to get much if any scaling at 4K in this game. I'm getting around 30-50fps here. Something is clearly not quite right. Is there a trick I don't know about? I have noticed I cannot find Fallout 4 in the drop down box of Nvidia Profile Inspector as a profile, and have to make my own. What am I missing here?
Two things, Ansiotropic filtering to 4x and Shadow distance to medium. I have everything else set to Ultra and I can maintain 60 FPS at 1440p. Shadow distance is the real FPS killer. If you don't have a Fallout 4 profile that shows in Nvidia Inspector that leads me to ask what driver version you're using.
For some reason in this title, setting AF 4X is smoother...less juddery, and adds a couple of FPS for no perceptible decrease in image quality. Bilago has a really nice config tool on Nexus for FO4. http://www.nexusmods.com/fallout4/mods/102/?
Personally, I've found that Fallout 4 SLI scaling is questionable at best. If I were to guess, I'd say a second card adds about ~20%. I wasn't monitoring CPU usage, so no idea if that was limiting it (at the time a 5930K OC'd to 4.5GHz).
The scaling is sh1t because of a poorly threaded gamebro engine. Try faster RAM mhz/timings and you'd be surprised on the increase.
Both shadows and godrays are highly demanding on CPU, big problem with shadows is that on ultra and high the distance settings aren't that different yet medium the settings have too low amount. So rather than just sticking shadows on medium it's best to go into the FalloutPrefs.ini and edit the following settings: fDirShadowDistance= fShadowDistance= The first one I believe is dynamic shadow distance, this is the biggest performance hit and should be set lowest. I recommend below 7000 for both settings as this provides a good balance between medium and high. Next shadow setting is: iDirShadowSplits= This basically controls the shadow detail pop-in, lowering it can increase fps. For godrays either have them off or follow this as a guide on how to reduce the performance impact of ultra (as other settings add pixelation): http://www.nexusmods.com/fallout4/mods/15211/?
I was on the newest ones, but I've removed and gone up to the hotfix 72's and the profile is there now. The one hard and fast answer in this thread seems to be tweaking various visual settings. Which does show how poor this engine is these days.
Done most of the various tips of what this thread suggested, thank you everyone for the ideas, and I do see a big boost in performance. It doesn't quite nail 60fps constant, but is more like 40-65 depending on location. Didn't think I'd have to reduce game attributes with this hardware, but apparently I did! Certainly better but still not really good enough!
It's better than you give it credit for. I ran it with one 980Ti and the performance was more or less unplayable. About 15-25fps I'd say. But the second one put it to around 30-50. Still pretty awful but scaling. Just.
Been wanting better RAM for a while now. The amount I have is fine, but 1866MHz is quite modest now. I want 3000MHz stuff.
Guys you can't run games in 4k yet... Not with a 980 SLI or a 1080 SLI , Im talking 60fps at all times and all details set to high. No matter what scenario you get 60fps locked ... The 1080 Ti cant do this either. Try the new nvidia GPU's coming in 6 months or soo and SLI them and I think you can get 60fps constant 0AA 16x AF all details set to high. thanks gl
I get 1 fps in any game I run at 4k so a 980 should give 30fps,, and sli give 45fps but there will be drops. Not until the new nVidia generation SLIed, then you can do your 4k Im shure. gl
Your CPU is not the problem, its plenty, resolution strictly has to do with the video card and video cards cant drive 4k yet. thx
Maybe a 512 memory bus with 8GB GDDR5 1080 Ti can give you a playable experience, but nothing to get excited about.
On a single GTX 1070 at it's factory clocks with a much older CPU I get around 45 fps average at 4k DSR. Keep in mind I don't have the high res texture pack installed VRAM usage hovers around 4.6 GB. I would of had a guess that it was your cpu holding you back, although I did see this vid of someone running it with 80% scaling: https://www.youtube.com/watch?v=EdUaaPytFaY I'm guessing you might of already tried that though?
Turn off godrays! That setting alone takes 50% of the fps. (and volumetric lighting if you need even better performance) Use fallout 4 tweaker for easy tweaking of settings. http://www.nexusmods.com/fallout4/mods/102/?
Yeah had a look at all this, and my performance is far better now, if still nowhere near locked into 60. But this was my point; my hardware SHOULD be enough to run this game at 4K at 60fps at max, but it isn't. The game engine is older than my nephew, more or less, and yet my hardware struggles with it at 4K? I should point out I too am using the ultra texture pack, but I am having to bring so many settings down to get a consistent framerate. Prehistoric engine, it really is.
Very odd. I decided to verify the cache and lo and behold I am now locked into 60 for the most part. We'll see how long this holds up.
