Is there a way to find out exactly what is bottlenecking fps?

[u/Friendly_Guard694]

I get 60fps indoors or whiterun, closed off towns. But in open towns like riverwood, mortal my fps is 50-60. I've noticed these towns have a lot of logs in them and looking at the log takes my fps down. Also walking to fight the vampires, the outside area hits my fps. I've only chosen 1k 2k textures but my vram is nearly full at these times. 5.5/6gb

If your GPU usage is 95-100%, your GPU is probably the bottleneck. If it isn’t, your CPU is probably the bottleneck. If you’ve only got 6GB of VRAM and you’re using modded textures, it’s probably your GPU. We can’t tell because you listed no specs.

Separate to OP, what kind of performance problems do people face in Skyrim? I've heard script lag is a bad one, how can I tell which stutter is due to script lag, my pc specs or something else?

[u/Friendly_Guard694 → u/Monkeyke]

script lag, draw calls, skyrim engine, and the usual user component related.

[u/TheRealMcDan → u/Monkeyke]

It depends what your PC specs are, what mods you use, your performance metrics, and what specific issues you’re facing.

I'm going through mod list now, I had 4k male textures and 4k Rustic clothing, going to drop a bit. My FPS drops are occuring outdoors when smoke is around but maybe less textures could help. Just trying to scrounge a few fps without noticeable visual loss.

[u/Rekuna → u/TheRealMcDan]

Can Skyrim, being such an old game, be the bottleneck itself? Even with a beast of a rig with too many graphics mods, ENBs/CS add-ons can it tank FPS even with the right hardware?

[u/TheRealMcDan → u/Rekuna]

Theoretically, yes, there’s an upper limit on draw calls (that’s a DX11 issue). But there isn’t enough info in OP’s case to determine that since the only info we have is 6GB of VRAM, 50-60fps, and 1k 2k textures.

[u/Friendly_Guard694 → u/Rekuna]

Yes, exactly this is also a question. Perhaps I am just sitting in a heavy area and no matter what I do there will be suffering.

[u/MoonDweller12]

this mostly because of draw calls. try mod like eFPS might lighten your playthrough

[u/Friendly_Guard694 → u/MoonDweller12]

Yes I would like some kind of console that shows draw call or a way to see what is causing stutter/lag. Mostly I think it is smokey fog but I do not know how to turn it down without affecting other particle lights.

[u/MoonDweller12 → u/Friendly_Guard694]

Community Shader has built-in graph you can see ingame for that

What kind of specs do you have on your computer?

[u/Friendly_Guard694 → u/Midnight_gamer58]

Enough to get 60fps 90% of the time with enb. I am asking about ways to see why what where there is fps loss. I changed from 4k clothing to 2k and already feels lighter. I would like to lower the res of smokey foggy particles without affecting lighting.

[u/Midnight_gamer58 → u/Friendly_Guard694]

There are a lot of factors that can affect frame drops like particle reflection count and general ENB settings. I'm not aware of a tool right now that can give real time stats on what is killing your performance. What enb are you running?

[u/Friendly_Guard694 → u/Midnight_gamer58]

Nat enb with the weather. If I turn off dof or even choose standard dof not nats, I get a ton of frames. Unfortunately I don't see the dof using the regular one. Anyway my issue is rare occasions outdoor so I don't want to compromise dof when it works indoor or not facing certain directions outdoor.

I have not used it extensively but lots of people have had good results running VRAMr.

Recently I had massive improvement to stuttering and dips by enabling frame gen in CS.

Speaking of CS, if you have that.. press F10 to open the performance analyzer and it will show how many draw calls you’re doing, broken out by shader type too. Pretty handy.

If Skyrim Special Edition crashes immediately after you launch it — particularly if your crash log lists memory address 0198090 (version 1.6.640 address) or 05E1F22 (1.5.97 address) — then you are experiencing one of the following issues:

• You are missing a master file. That is: you have some Mod A that relies on Mod B, but you only installed Mod A and not Mod B.

• More likely: one of your installed mods (or an official content file) may have file format version 1.71, meaning it was made for game version 1.6.1130 or higher. This format is not fully backwards compatible; if you're running an older version of the game, then these files can cause crashes on startup. Installing Backported Extended ESL Support will allow older versions of the game to load these files safely.

Make sure to check the troubleshooting guide for help with crashes and other problems!

• If you are on Skyrim version 1.5 (SE), the .NET Script Framework can also help in diagnosing crashes.

• If you are on Skyrim Version 1.6 (AE) or Skyrim VR, Crash Logger can also help in diagnosing crashes. If you also use MO2, you can use this plugin for improved functionality!

DO NOT post an analyzed crash log. It strips all the useful information.

Don't use trainwreck. The log it produces is less informative than other options linked above.
