Fallout 4 Anomaly

Hi all,

I've come across an anomaly which i can't explain.

https://www.dropbox...._xFyRMOJra?dl=0

^^ in the drop box are 3 x pictures which show my FPS @ 1080p, 1440p ^ 2160p at the exact same loading point. I took these pictures after the game had loaded and allowed 1 minute for it to 'settle in'

1920 x 1080 = 53fps GPU 47% CPU 60%
2560 x 1440 = 56fps GPU 63% CPU 65%
3840 x 2150 = 52fps GPU 99% CPU 69%

How on earth can i get such tightly knitted FPS !

Its clear the larger the resolution the more the GPU/CPU is increasing in useage, however its puzzling me why i cant hit 60fps across any of the 3 resolutions.

Spec :

i5 4670k 4.2Ghz | Evo 212 | MSI Z87 G45 | EVGA SC ACX 2.0 980 Ti | Hyper X 16GB 1600 | Samsung 840 Pro 128GB | Crucial MX100 128GB | Seagate 2TB | XFX PRO (Black Edition) 850W | Define R4 case | Acer XB280HK (G-SYNC)

Ideals ?

HA!

will someone please tell me why the CPU is not 100% - i'd understand if it was a bottlneck if it was maxing out - but 60 - 70% is not a bottleneck - can someone explain ?? sorry im not trying to be a pain in the arse just trying to understand!

Cheers!
 
I've checked and all 4 cores are running between 50 - 70% on all resolutions, and its got me perplexed.

If all cores were 100% - then it would be logical to say its a CPU bottleneck, but in this case none of the cores are at 100%.

wait there i'll post another image showing individual cores :)

As you can see all cores are betwen 60 - 73%

This only happens in Diamond city or other huge towns when there's a lot going on. everwhere else its 60 fps constant.

The engine will never use 100% because it aint properly threaded, It is grabbing everything possible at the minute i suspect and it still just aint quite enough. Your CPU has 4 threads at 4200mhz i think ideally most people are 200-300mhz higher and the ram is only 1600mhz. Again that memory is probably not far off twice as slow as a 2400mhz kit with timings tweaked. If you expect 100% usage on all four cores from what is essentially modded Skyrm forget it.


I remember playing it in Jan (Skyrm maxed) with my 4770k 2400mhz ram and a 980 @ 1550mhz and i still dropped down to 90 from 120 thanks to the CPU. The engine requires quite a lot of brute force from a cpu i would guess it does not even care about core and would instead gobble down ram and frequency like no tomorrow.

Would an i7 4770k/4790k improve the games performance ?

i'd sell my CPU and buy a 2nd hand one if thats the case.
 
i plan on running extreme mods like i did with skyrim ENB's etc....

if its a CPU bottleneck then i'll get a 4790k or a 5820k , the 6700k is £350 alone which is redic imo! :)

The big cities are known to tank FPS.

Happens to me with a 5820k and 980Ti. I can noticeably feel the FPS drop to 40s sometimes. Turning down shadow detail fixes it.

Terribly optimised game basically.

I hope they fix it!

there's no way we will be able to run top end 4k mods / ENB's like skyrim had in that case. It's nice to know someone else with an i7 6 core beast is experiencing the same as me.

Would you be prepared to run a small bencmark on your PC for me ? i could send you my graphic options so you can duplicate them and the save file and can you tell me what fps you get on your i7 with the exact same save file ? - this will tell me if its an i5 bottlneck thing or not - i'd be forever greatful as im seriously considering getting a 5820k.

Go online and see the % increase and you will see you will not gain that much imo. Would he get 30% guys? I personally think they either need to fix the engine or everyone will need whatever is coming next from Intel? As i said i would wait for patches and better hardware. Do you really need to play it right now? Why not put it away until Christmas or better yet next Christmas? Then you can buy Cannonlake and DDR4 4000mhz. Skyrm and Fallout will still probably laugh at it tho! ;)


I personally try a game and if the fps is like you describe i leave it sitting until i have better hardware. But like i said elsewhere this cost me missing out on Fallout 3, But i nailed 160 hours into Skyrm.

Don't get me wrong, the game is 60fps everywhere else and 52fps is defo playable and its beautiful in 4k with gsync, But as you know adding ENB's and 4k textures etc.... pulled skyrim to 40 fps on my 980 ti. God knows what would happen to FO4.

I've got 2 weeks off work to play this mate - i'm loving it, but just want to rule out if its an i5 bottlneck and if an i7 would resolve it. i know Skylake > haswell by ~7.5 instructions per cycle for games.

Yes you sound just like me playing Skyrm. I was happy with the game but the dips annoyed me and to be honest had they exluded MSAA i duno where i would have been with my hardware. It seems if you want a framerate that does not dip in thier games like Skyrm and FO4 you need absurdly over-spec hardware. The more i look, The more i see no cpu on earth is going to power that without dips. You really need an insane memory speed and IMC. This is really the only area Intel are moving in thankfully. It worrys me i really wanted to play this in 4K but if a 980ti is getting 40fps wth do i need for 120?

Three way is not even realistic. I will be lucky to run this with Pascal it seems christ i am angry now. :eek:

Don't be disheartened, the game runs REALLY well on 4k i average 55 fps on an i5 / 980 ti combo - but that's vanilla fallout 4.

When the modding community over at nexus get ENB's / shaders and 100's of 4k texture packs, you'll need an 18 core 32 thread monster and possibly Titan SLI to run them - which is absurd.

if an i5 / 980ti cant get above 52fps overlooking a city @ 1080p, it HAS to be the engine which is at fault or the CPU, my moneys on the engine.
 
i managed to find the culprit - it was shadow distance, as soon as you go above medium to, high or ultra, it saps your system completely.

Final Settings:

Resolution - 3840 x 2160 ( Windowed Borderless - to fix Microstutter but lose ~3fps)
Antialiasing - OFF- increased FPS @ 4k
Anisotropic Filtering - 16 Samples
Texture Quality - Ultra
Shadow Quality- Medium - Best for performance / vidual fidelity tradeoff i found
Shadow Distance - Medium - Best for performance / vidual fidelity tradeoff i found
Decal Quality - Ultra
Lighting Quality- Ultra
Godrays Quality - Low - higher settings i dont see any difference but a massive drop in performance
Depth of Field - Standard
Ambient Occlusion - SSAO
Screen Ambient Reflections - Disabled
Wetness - Enabled
Rain Occlusion - Enabled
Motion Blur - Disabled- personal preference
Lens Flare - Enabled
