Alright folks so I have a pc with an i7-2600, 12gb 1600mhz ram, and an rx 570 4gb and fallout 4 STILL drops to below 30fps around diamond city and near swans lake or just pretty much anywhere in the big city and it's pissing me off because I just dropped 95 dollars on this cpu and literally nothing changed I would love to see what everyone has to say, oh and by the by I have my shadows at medium both quality and distance as well as God rays and am running about 67 mods but most are little things and it still does it without them. It'll run fine I have it capped at 30 to try to help, and it'll run fine but then once I get into the city I get lag spikes bringing me to 0-3 frames and then it mellows out at 30 again, the problem is I don't think it is standard load in stutter it does it and then is fine but when it does it it can last up to 20 seconds
 
Solution


Maybe, Vsync in games are often different how they perform than the driver's version. Thats why i thought to disable in-game's Vsync from having any affect and let the AMD driver take over.
 
Hmm I am using amd though now, ik my answer was a bit confusing to read. Unless you have got more for me that sticks out to you it's fine, I'll just play as is or play something else I just thought my new part would make a bigger difference. I really really appreciate the time and help you've put in though
 





Nah that didn't help, more cores the better from what I've seen experimenting here thanks though! I'm still trying things here on my end, not to any great results either

 
My weekends are split in my schedule and I've been trying stuff all day for this part of my weekend so I might call it a day as far as fallout 4 optimization goes, but anything you put in here I'll try and get back to you about next time I get the chance
 
Okay so here is something really really weird. I tried downloading an enb called vogue enb and a shadow stutter decreasing mod, neither of them worked but when I deleted them the next time I opened fallout my frames are much much better, I still experience spikes that bring me down to zero but the performance in between is vastly improved. Like I said very very very weird.
 
Oooooh I understand, no I'm not running 2x6gb but I only installed the extra 2x2gb today! Didn't make much of a difference in fallout 4 though (it made a huge difference in an awesome game called kenshi but that's besides the point)
 
Think Madmatt30 meant bank a and b, he knows 6GB dimms don't exist.

Read your manual where to place for dual channel memory with four sticks.

A1 and B1 slots = 4GB sticks
A2 and B2 slots = 2GB sticks

Says in the manual A1 and B1 need to be identical in size and same for A2 & B2.

So the closest dimm slot from cpu is A1 and 3rd slot from A1 is B1. Those two slots have the 4GB sticks or 2GBs, not mixed. Ie, if have A1 4GB & B1 2GB would knock out dual channel.
 
I had the ram in right I just didn't understand the question is all haha. I also had no idea there is no such thing as 2x6gb. But anyways I think for now my fallout 4 is as good as it's going to run for me I feel as if I've exhausted every option available. Really and seriously thank you to all of you who answered my post I've been working at optimizing fallout 4 to my pc to no avail for almost a week and have gone through a processor upgrade to no avail, but all the posting going on here I think I just need a better pc in general or to give in to the choppiness and deal with it. But honestly I don't think I'll do a new build just for fallout as this runs all my other games with ease. Fallout is just my favorite series and has been since the dawn of fallout haha even played the on-the-down-low tabletop rpg for a time. Just wish fallout 4 ran better :/ at least new vegas is flawless and a new run through is probably due anyways. Thanks again everybody on here really appreciate all the feedback and assist throughout they day I didn't expect such good timing on responses or consistency on responses throughout the day, it was awesome! Special thanks to boju for doing all that research today for this fallout nerd
 
You speak the truth haha, but when it works the detail and frames are worth it! One last question ik it might not belong here but the rx 570 4gb I'm running is it a good gpu for gaming? I bought it on a whim at frys electronics with little or no research, if it's not too difficult to answer, is it on par with any specific modern nvidia gpu?
 
If you're very far into the game and have placed lots of structures etc Fallout 4 gets pretty cpu demanding. Also, most mods obviously add to the game's CPU use.
Check a very early savegame (like when you first get to your base) to see what your FPS is.
Assuming you're playing at 1920x1080 you should be comfortably getting close to 60FPS there on medium settings.
My non-overclocked 2500k with a GTX 970 was around that, quite comfortably I might add.
 


I had this problem. Its to do with the Vsync. I had a 2600 and a 390 and it ran perfect after fiddling around a bit. Your specs are fine and should get 60fps all the time if you keep god rays off and lower shadow details etc a bit. Try "Dynamic V-Sync" i think it was on the Radeon control panel. Nvidia its "force adaptive vsync" or something. This solved my problem when it was doing this.
