Fallout 4 Performance with ENB and mods

[EchoNineBlack]

I have about 105 esp and a few esl/esm mods installed using Nexus Mod Manager. The most intensive are the Boston Natural Surroundings, ConifersRedux, a particle effect enhancer and Fallout HD Rework Project along with HDCreature mods. I use the PRC Ultimate Immersion ENB with some effects disabled for performance along with NAC. the other stuff are mostly gameplay related or weapon and armor mods/building material mods that I haven't used at all, yet. I haven't touched FalconOil's stuff because they were 4k and I didn't want to break my game. Yet, I barely get 30 fps in boston area (around Combat Zone), around Goodneighbor and inside Diamond city.

 

Initially I thought my system wasn't keeping up (Ryzen 7 3700X on an ASUS Prime x470 board, Vega 64 and 32 GB of DDR4-3000MHz RAM). I installed MSI afterburner to check my performance stats... My GPU never went above 65% utilization, my CPU never hit a sustained 37% usage at 4.2GHz and my RAM never exceeded 4GB usage. Some digging provided the info that my RAM was only operating at 945MHz in the game. For a sanity check, I hopped into GTA V modded with GTA V Redux and some crazy ReShade presets that I have added more stuff into - I would get steady 45fps at Ultra and the RAM would work at 2866MHz (CPU was 54% @ 4.25GHz and GPU was 80+%). In all my testing, I made sure that temps are always around 53 Celsius.

 

I have done some further testing and the problem in fallout 4 seems to stem from the fact that I only have an HDD.

 

I would really appreciate is anyone can help me understand and hopefully solve my problem - I used to get locked 60fps with some low impact mods (so no idea about max fps) but I don't think this is a normal scenario.

it would be nice to know what resolution you are using and how many fps you get. my 1080ti is at 100% playing in the exterior with ultra settings at 3k res with around 40-50fps. your cpu is more than enough, ram is ok, your gpu will be ok up to 1440p and ultra settings. the problem is the gpu utilisation in your setup. it is weired. check energy magement presets for gpu and win 10 and change all to full power. if this is not the reason check your gpu driver or update it. gpu utilization definitely is too low and the reason seems to be not the cpu (if not running without a cooler). if you have HBM VRam 950Mhz seems to be ok.

If you set the game settings to Ultra, it could be that Shadow Draw distance is the culprit. It's heavily dependent on the CPU but it will still bottleneck even if your CPU seems to be in idle. Fallout 4 isn't properly multi-threaded and uses a single core for a lot of stuff (esp. rendering). FO4's major limits are draw calls because of DX11's driver overhead. Just a single mod that breaks PreCombined/PreVis will ruin your performance.

 

You may want to drop shadow draw distance down one stop (to high) and test it again. Esp. downtown that one setting has a huge impact on performance.

 

A HDD will slow down loading, but as soon as the cell and all assets are loaded into memory, the HDD shouldn't have an impact on your framerate (as long as you don't move to another cell that has to be loaded).

 

I haven't tried Boston natural surroundings yet, but even with a lot of 4k texture mods and other graphics heavy mods, I can keep my 60fps (most of the time) even downtown. But I also don't use an ENB as it created lots of problems for me like stuck mipmaps (textures stay blurry) and some performance problems here and there. You can easily test whether it's the ENB or not. Just rename or move the .dll of it and launch the game.

i would strongly suggest placing BostonFPSFixAio, very last in the load order, as any mod that breaks precombines will override this mod if placed lower then said mod.

 

thats where i have currently placed mine, and so far no issues, with it having maximum priority. 250 mods.
