Fallout 4 FPS might depend on your RAM speed

[dimitriianghelov]

while the performance is not great the bugs is what killed it for me, you trip and die at full hp even in power suit... it's fucking retarded

[Ohlyver]

Interesting that they get such results,

My build does not meet the minimum requirement for the CPU. I got a G3258 OC'd to 4.3 paired with a gtx980.. Got an ssd and ram is at 2133 ... The game is set to ultra at 1440p yet I get a constant 67 fps that dipped no more than four times in 2hours + gameplay... Go figure..

[ChrisxIxCross]

Certainly happy about having my DDR4 3000mhz Dominators then!

[Doobeedoo]

Well, that is something. My 16GB 1866Mhz will be ok heh

[Bouzoo]

5820k, 2400mhz ram, 2x Fury X (but the second one doesn't matter due to frame cap in game). most of the time at 60, then random shit causes 30 fps dives, but that's Bethesda's shitty programming not the Fury X.

 

Afaik SLI doesn't work, does the same go for CF?

It's Bethesda - nothing works

couldn't tell you as I have a 60 Hz monitor and FO4 has a cap of 60 fps for 60 and 120 Hz and 72 fps for 144 Hz monitors. although I don't notice a difference in fps dives/low fps areas between 1 and 2 cards so CF probably doesn't work either.

@App4that - have you tried this btw? Seems like something worth taking a look at.

OK, reporting as promised.

 

With shadows set to medium and God Rays set to high. In crossfire I'm pegged at 60fps in Lexington even with ghouls attacking me, though with the crossfire forced the mouse controls when hacking is very unstable. Just using the 390 the worst dip I have seen so far in Lexington even attacked by Ghouls is 50fps, smooth as silk.

 

So if anyone is having a problem with fps drops, go to medium on the shadows and at least high with the god rays, everything else is maxed.

 

4690k @4.6GHz

16g DDR3 ram @1600MHz

Nitro 390 (ran at stock clock and a overclock of 1100, the stock clock was fine for holding FPS)

Vapor-x 290

If you have trouble maintaining 60fps and your gpu isn't being maxed out, I have found it's not a cpu bottleneck but an engine problem where if you set the shadow draw distance setting passed medium you can take insane performance hits in cities for no apparent reason. Even since I lowered that one setting I don't think I have ever fallen below 60fps.

I can confirm that there's a huge performance increase when I set the shadows to medium. I used to drop to 30fps on high settings but now I only drop to 45fps on ultra.

So CPU are getting smashed by higher Shadow settings then?

Sorry, I meant shadow distance*.

I wouldn't be surprised if Nvidia managed to find a way to add Tessellation to shadows - that or Bethesda being Bethesda

[Albatross]

So I decided to try it. I oc'd my ram and now I'm getting 50-60fps almost constantly, except in big battles and Diamond City of course. I was able to actually keep almost all of my settings on Ultra (God Rays to High really helps though), as well, so yay for that.

 

Really odd, but I guess I'm happy something helped me out of my horrible 24fps drops...

I'll try that next, thanks for sharing.

Shadows is where the problem lies, anything past medium causes problems.

Told you - it's not all on the driver - half of it is broken shadows and a RAM fetish from the engine

[KingKeith55]

Glad I went with some more expensive RAM.

 

Runs at 1866Mhz but I could probably OC it quite a bit (since it's hyperx' high quality stuff)

[ThreePinkApples]

So I finally have a use for my 2400mhz RAM I bought on sale two years ago? Sweet!
Now I just have to be interested in the game

[Sakkura]

Single channel DDR3-1600 (what I use) is 18GB/s transfer speed, why would a game need more than that???

 

Single channel DDR3-1600 actually only has 12.8 GB/s bandwidth.

[You_are_a_cunt]

Now I'm half tempted to OC my ram and GPU in the hopes of getting 60 FPS and be able to roflstomp people with $1.5k PCs

[Aniallation]

[Sakkura]

 

 

MaxxMem is known for inaccuracy. DDR3-1600 single channel transfers 64 bits 1600 million times per second. That's 8 bytes times 1.6 billion (giga) per second = 12.8 GB/s

 

DDR3-1600 is also known as PC3-12800, labeled for the per-DIMM maximum bandwidth in MB/s.
