New survival playthrough has huge FPS but never happened before

[1Luv4SF]

I get constant drops into the 40's every 7-10 seconds or so. And I loaded a non survival version of a late game character and had absolutely no frame drops at all. Im using the same mods for both characters so it makes no sense. Ive even turned off all my graphical mods AND cranked the settings way down. I have an i7 7700K and GTX 2080Ti so I know its not my hardware. Why would starting a new game give me this problem?

Hi

 

I play survival with a 2080 ti as well.

 

I play using an i7 8086k overclocked to 5ghz on all cores. My old i7 6700k overclocked had similar performance to your i7 7700k. It could only run my game to about level 20 before it became unplayable. Then I moved the save to my i7 8700k computer to continue. That is why I retired my i7 6700k.

 

Fallout 4 is the only game that I have to add an overclock to the 2080 ti to play at 4k 60fps. I wish that I had bought a 3 fan version because it sound like a vacuum cleaner with the overclock.

 

So in my experience your hardware can be a problem depending on your mods and resolution you play at. This game modded can overwhelm any hardware on the market today. The hardware I need to continue to mod my game does not exist.

 

I lost performance in Survival mode as well. I think it is the more complex scripts for things like tiredness, hunger and thirst. I know that the mods I use in Skyrim that do these things help to bring performance down as well. I also think that if I did not use mods like Sim Settlements and better settlers, survival would not be as big an issue. This is just a guess but until someone gives me a better explanation I will go with it.

 

I think you should run the game with Fallout Performance Monitor to check CPU, GPU and i/o usage.

 

I/O performance in this game is important because NPCs and mods like Sim settlements can cause load-in stutter if the game is on a hard drive and pauses even with the game on a SATA SSD. I will be upgrading from a SATA SSD to a M.2 NVMe drive(2tb 970 EVO) to try to get rid of the issue.

 

For GPU, frame rate only rapidly drops in the game with a 2080 ti if it hits 100% usage. That is why I overclock my card. I use Precision X1 and set the power target to 130%, add 200 to the memory and only 117 to the clock. This brings my reference PCB card to the performance of a much more expensive card and that is all the noise I can stand.

 

For CPU usage, the lows in the game are determined by the IPC of your CPU and the overall frame rate is determined by your CPU usage.

For a 4 core CPU your average usage should be about 24%. Any higher and you are losing frame rate. With my 6 core it is 17%. At 42% usage(Boston) anything below a i7 2600k will see frames drop below 60fps no matter what GPU you use.

For the 4 CPUs I have used playing the game the lows are as follows.

 

i7 2600k lows in the 30s

i7 6700k lows in the 40s

(your CPU is between these 2)

i7 8700k lows in the 50s

i7 8086k(5ghz) lows in the 60s

 

So when I am play testing and have vsync off my frame rate is between 80 and 110fps at 4k. If GPU usage hits 100% the frames drop to around 54fps. With the GPU overclock that changes to 57fps but I hit 100% usage way less. Any CPU hits bring the frame rate down to about 64fps and I only see them and don't feel them. I/O hits in my game are in rings around built up settlements. They are slight pauses with a SATA SSD and heavy stutter with a Hard Drive.

 

Hope this helps.
