Fallout 4 Performance driving me nuts

[sepheronx]

Comparing a 4.5 ghz cpu to a stock 3770, no wonder the 3770 is slower.

Stock 4770.

OP uses 4770

Not much different from 2600K at 4.5


OP you don't use adaptive VSYNC do you?

Stock 4770.

Still - 3.4 base clock against a 4.5 processor - useless comparison

Well, it runs at 3.9ghz when I am playing the game thanks to boost, and I monitored that. But yes, still no comparison.

Doesn't matter much to me anyway. The clock speeds are not the problem. The Ram speeds are.

Yes, adaptive.

We've established it's your ram speed - las jumped in comparing a overclocked 4.5 2500k to a stock 4770 and 3.9 ghz is boost clock on one core.

Oh well, not going to buy new ram just for this game. Unless someone wants to sell me 2400mhz 16gb of ram for cheap. Otherwise, screw it. Will just have to adapt to it for now. Game is OK, but not that good, especially for its really poor optimization.

16gb ddr3 2400mhz inside

Pretty much.

Ram is overpriced. That is the reason why I went with the current setup I have. Ram alone for DDR4 would have cost me half the components I have now excluding the GPU.

Base. Clock.

 

[Deleted member 178884]

Base. Clock.

Correct base clock, it boosts on one core, that's 1/4 being boosted, Not a massive difference. Besides ram speed is the problem, that 2500k rig owner also has faster ram.

Listen, if your performance is terrible, it's not your memory. 1600/CL9 is not that bad.
You can try OC your memory. Don't expect a miracle.

Don't sweat it tho. The game is overrated and repetative.

Nah. It boosts to almost 4 GHz on all cores.

He says 3.9ish GHz ingame.

Some games are highly dependant on fast RAM and Fallout / Skyrim and the like fall square in that category. Ever since the PS4 and X1 launched, the importance of faster RAM, but also faster storage has increased rapidly, because a lot more assets are 'streamed' instead of pre loaded these days. Its the worst way to scale performance but that's what it is and consoles only have one performance level anyway... Regardless, even faster RAM will still not make a noticeable difference on an old platform for this game, so... yes. Don't sweat it IMO.

Ever since DDR4 and even regardless of games being console-first, we've seen big performance jumps since Skylake and the main reason was (faster) DDR4. Upgrading to faster DDR3 doesn't really compare.

Precisely, it makes more sense to wait out 7nm processors to upgrade, that'll be a far bigger upgrade than what the OP has - but it'll suffice until then.

I just came around and play Fallout4 just few days ago and exhibit similar problem. I done few things to mitigate it.

First open up fallout4.ini and look for iPresentInterval and set it to 1, this will remove the in-game Vsync and use some other programs like nvidia inspector or MSI Afterburner to limit the game to 60fps. The game physics is tied up to this, if you increase it will make things speed up. The in-game vsync don't work too well and gives jittery performance.

Second look for fMeshLODLevel1FadeDist= and fMeshLODLevel2FadeDist= and set it to 20000.00, this is done to reduce low resolution texture pop up. Open up Fallout4Prefs.ini and set up the same here too.

EDIT: Forgot to say reduce shadow quality and detail to medium in the launcher plus lower godrays quality to low or turn it off completely. Make sure you back up both fallout4.ini and fallout4Prefs.ini first and after editing make the file read only so it won't be changed by the launcher.

Try that and see if it improve things for you.

Put shadows to medium and lower the shadow draw distance.

Shadows and lighting is a single threaded mess in that game, just that one change will give you the performance you're looking for.

Just as a note, I had set in MSI afterburner to monitor CPU usage of each processor of my 4770. Core 1 is the one that is always used and it goes as high as 60% but when I am in the city and FPS drops, so does the CPU usage of Core 1, which then becomes about 33%, right around same time as my GPU does too.

I noticed everywhere else though, no issue at all. Just cities.

Was just reading people on reddit that have Core i7 7700's and same GPU as me with exact same issue. Dropping to about 25fps in boston area, depending on which direction character is looking. Same issue as me.

I know it isn't throttling or any of that. If it was, it would be showing in other demanding games were I see exact same temps in, but no slowdowns at all. It is just Fallout 4.

That specific big FPS drop especially when looking to specific directions is the well known problem of their game engines since Morrowind, Oblivion, Skyrim until Fallout4. Unoptimisation in its full glory...

 

[crazyeyesreaper]

For shits and giggles check to make sure memory is operating in dual channel. Dumb as it sounds it can have a HUGE impact on performance. Seen it in multiple laptop reviews where GPUs like a 1070 perform closer to a 1050Ti / 1060 because of memory bandwidth issues related to single vs dual channel

Its likely not a memory speed problem per say but could be bandwidth related. However it could also be bad code. I would look into the unofficial patches etc and see if they make any improvements.

No dice comrade. Tried, doesn't work. Same results. Tenpines Tower area goes down to 20's.

Done that. Its in dual channel mode. As well, got the unofficial patch.

Yeap. This is most likely. If other people are commenting having exact same issue, and others here also saying they had/have same issue with this game, and they got more powerful machines, then yeah. Seen CPU spike at most to 75 celsius but it drops back down to 60. Spike happens for a second.

Oh well.

Already had that done. Mentioned in first post I believe.

Correct, you can't really fix the FPS in town. There are simply too many assets packed together too densely. The moment you enter a building through a loading screen, your performance will probably be fine again. Enter the open world again, and back to utter crap. Its real simple: shitty code, ancient engine, lazy map design.

Just for those who are curious or may have missed some details:

yeap, load times skyrocket once leaving a building and entering downtown. Even game crashes if I die in downtown area.

The most silly thing about this, is that in Fallout 3 they understood that limitation of the engine - they used lots of very simple, low poly buildings for the skyline and you run into all sorts of invisible walls there.

 

[sepheronx]

Added Speccy pics too.

 

[crazyeyesreaper]

Quickest way to improve performance is to overclock the CPU and the NB,

The NB will boost memory performance and throughput which will help your minimum FPS. Its not a huge difference but depending on the location you can see a 3-5 fps boost on minimums. Depending on how high you can go in terms of stability may result in bigger gains. Typically 4.3 on the cache is easily attainable on most 4770k CPUs and a core clock of 4.3 will be a 1:1 ratio.

 

[sepheronx]

Issue is.......its a 4770...not a K Now. If you got one for sale, I'll buy it (cheap price though, cause I am operating in canadian Rupees).

Serious note though, I am thinking of buying a better cooler and will attempt to overclock. But my understanding is the non K cant really overclock.

 

[crazyeyesreaper]

Yeah non K your probably stuck for I basically just assumed 4770k since most people didnt bother with the non K chips. Your basically stuck, For games like Fallout 4 / GTA V higher speed memory with a higher core and cache clocks you can see minimum FPS boosts of up to 10 depending on how high the cache will go.

Everyone thats meh on Fallout 4s performance don't understand that the game is script heavy and tends to bog down 1 core. Memory / Cache speeds etc influence performance greatly with the CPU typically being the deciding factor, Its one of the few games that is sensitive to memory / cache performance.

I have no performance slowdown issues or problems with Fallout 4 like most people have but then again the issues that plague Fallout 4 have been present in all of Bethesda's games and the issues can be mitigated. Nothing has changed since The Elder Scrolls III Morrowind. (Morrowind / Oblivion / Fallout 3 / Fallout New Vegas / Skyrim / Fallout 4 / Skyrim SE all basically use the same engine on a fundamental level, To the point assets and scripts from Morrowind (2003 release) can in some cases be directly ported over to say Skyrim SE / Fallout 4 with relative ease. Looking through game engine code even the newest versions still retain code references to the NetImmerse Game engine which is what Gamebryo ( Oblivion) is based on and then the subsequent Creation Engine as well.
