Fallout 4 i5 Bottleneck or Poor game optimisation? : Fallout 4

» Fri Nov 27, 2015 9:21 am

Hello all,

I need some help with Fallout 4 with FPS.

I have run the game with the everything on ultra, except AA = off , Shadow quality = medium , Shadow distance = high.

I tested 3 x resolutions and used MSI afterburner to measure each of the 4 CPU core load % and GPU load %.

I loaded a game save which overlooks Diamond city from the entrance stairs, waited 1 minute for the game to load/settle then took screenshots for measurement purposes.

1920 x 1080 = 53fps GPU 47% CPU CORES: 68 - 54 - 65 - 73

2560 x 1440 = 56fps GPU 63% CPU CORES: 72 - 64 - 70 - 75

3840 x 2150 = 52fps GPU 99% CPU CORES: 70 - 67 - 69 - 75

As you can see, with the resolution increase the GPU load increases, HOWEVER the CPU load doesn't change much, and as a result, the FPS are very similar. There is no imrpovement in fps from 1080p to 2160p

Either the i5 4670k @ 4.2Ghz is bottlenecking, or the game is really poorly optimised in main towns and city's (a bit like Dayz!)

When the modding community release ENB's and 4k texture packs you're going to need an 18 core 32 thread monster with 3 x Titan Z's to get 60 FPS if we learn anything from Skyrim modding.

Can bethesa or anyone really techhie here explain whats happening ?

specs :

i5 4670k 4.2Ghz

Evo 212

MSI Z87 G45

EVGA SC ACX 2.0 980 Ti

Hyper X 16GB 1600

Samsung 840 Pro SSD

XFX PRO (Black Edition) 850W

Acer XB280HK (G-SYNC)

Most modern games are driven by the GPU. Its not an optimization problem. The GPU is better at doing the calculation that make a game work. The CPU mainly deals with background processes, although it still factors in game performance.

Are you using V-Sync? From the framerates and utilization you can definitely tell that the 980 Ti is being maxed out 2060p, which makes sense, but you're still getting great performance. Yes, if you add texture mods you might need a NVidia Titan GPU, but you shouldn't need any more CPU processing power.

What are your VRAM allocation figures. I run at 1920x1200 and it uses ~1860MB (Ultra, everything maxed). You are probably near the 6GB limit at 2160p?

How much RAM does the game consume for you Níeh?ggr? Does it consume more then 8GB if more than 8 is available? And I concur that a Intel i5 and i7 3000 series desktop CPU should be good enough for every game available now (Except maaaybe at absurd resolutions) so your CPU is well and truly well equipped for this game.

I've ran vysnc on, off and Gsync - no difference.

1080p runs the same fps as 4k when overlooking a city. :brokencomputer: Vram was 3.8GB @ 4k- thats 2GB to spare.

I have 16GB ram, its not a RAM issue.

Right now, its 6950MB, however this could go up. I see why there is a 8GB minimum.

VRAM use increased to 2200MB.

That particular question of mine was just me being curious, I didn't mean to imply that any of you were running in to a issue because of RAM. Since I don't have more than 8GB I can't check it out myself, hence the question.
