SSE FPS Stabilizer (by Shizof)

SSE FPS Stabilizer by Shizof

I'm sure everyone has at least heard of this mod by now. The default settings mainly alter TerrainManager LOD settings higher/lower as FPS increases/decreases, but it can be configured to dynamically adjust any INI setting higher/lower as the FPS increases/decreases. Below is the customized INI file that I am using with this for testing, which is geared toward higher-end hardware.

Interesting ... but further complicates display config, LOL. It could take us months to agree on optimal configs with this one in the mix. I don't want to offer every scenario or maintain those instructions in our guides. Maybe some suggestions is all or for the most common setup.

Remember, every time one of these mods is updated, we would need to spend a lot of time adjusting (and debating) the changes to our recommendations. PC envs are just too variable.

While not a deal-breaker, I'm thinking this could become a support nightmare for the STEP team.

I have noticed it does save SkyrimPrefs.ini settings. I don't really see any issue with this, however, as long as we use good settings. I think this is probably a good thing, as it will mean that when you reload an area, the settings will persist, and you won't need to wait for it to lower the settings upon reload.

I don't have a problem with it either personally. I was thinking that with this mod your 'baseline' configuration will become meaningless, as it can't be used as a reference point anymore for supporting users with performance issues.

If you're confident you can find a good set of settings for each LevelN that provides adequate performance for everybody, then that's great and I'm all for it.

I think it very possible that we will need multiple configs, such as low, medium, high. But, especially if you could test and advise your performance, that would be great.

@DoubleYou Thanks for providing a config file. I am using it as is and will report any findings when I find the time.

I don't know why but it doesn't touch mine, nor Skyrim.ini for that matter.

I tried your INI configuration. FYI, it looks like 'fBlockLevel2Distance:TerrainManager' is ignored. You can see it complain about 'setting not found' if you turn on logging in the mod's INI.

For example:

Switching to level 1 - Angle:324.719 - CurrentFPS:54.054
New setting (fBlockLevel0Distance:TerrainManager): 53248
New setting (fBlockLevel1Distance:TerrainManager): 159744
setting not found (fBlockLevel2Distance:TerrainManager) <----- HERE
New setting (fShadowDistance:Display): 8145
New setting (iShadowMapResolution:Display): 2048
New setting (fMeshLODLevel1FadeDist:Display): 10240
New setting (fMeshLODLevel2FadeDist:Display): 14480
New setting (fMeshLODLevel1FadeTreeDistance:Display): 10240
New setting (fMeshLODLevel1FadeTreeDistance:Display): 14480
New setting (fTreesMidLODSwitchDist:Display): 14480
New setting (fLODFadeOutMultActors:LOD): 11
New setting (fLODFadeOutMultItems:LOD): 4.5
New setting (fLODFadeOutMultObjects:LOD): 14

Interesting. It would seem that some settings may not be supported. I will have to make sure I enable the log as I test the different ones.

I think this mod is good for the console feature, but the dynamic INI settings seem to be only useful for testing purposes IMO. As a method of validating performance-impacting INI settings specifically. Using the log to verify what setting tweaks result in beneficial impact.

I would not run with this mod otherwise unless it is being used to resolve some nagging performance issues. And then it is likely still best to use it to seek out more appropriate INI values for key INI settings that impact performance. Maybe throttling this mod to only certain key settings to be dynamic would be best (e.g., terrainmanager), but I think it is highly experimental and would not recommend using it for Step as a blanket approach. The TargetFps setting should be set to a realistic value and NOT what you are using as a frame cap necessarily. My cap is set to 141, and I rarely get that outdoors but often indoors and always in menus. TargetFps for me would be something like 50-55, which is what I see often in game. I would rather have consistency of visuals than consistency of frames.

At the end of the day, I think it is best to set optimal static INI values as always. Seems like mileage will vary significantly, and troubleshooting/conflicts/obfuscation of legit issues will possibly be exacerbated by this mod.

Definitely a fun mod to use for testing/tweaking, but not as a blanket solution for Step, IMNSHO.

You evidently haven't enjoyed the pleasing effect of 8k shadows in interiors.

I'm revising my opinion a bit on this mod. If DY's settings are used and I set TargetFps to a reasonable value (50) based upon my actual FPS in game where I struggle (40 FPS in places on the tundra), then this mod does a good job keeping me near 50 FPS. In these lower-performance areas, I spend most of my time switching among Level5-9. Indoors and in town, I spend most of my time in Level0-2, depending. I don't notice any real degradation while playing, so that's a plus. And shadows indoors and in town ARE very nice with DY's settings. I haven't notice shadows are bad outdoors, and tree skinning seems fine.

This mod does not write to my Skyrim.ini or SkyrimPrefs.ini files, so it must be setting these INI values in memory.

I have my 'blank' SkyrimCustom.ini set to read only, so it is never used (and MO doesn't care in the least about this, as I have mentioned. This file does nothing at all for me that I can notice). I will test with it at some point, but I'm not motivated to do so without good reason (i.e., something is not working).

That has been the main goal I have had for this... make changes that are hardly perceptible but improve performance in bad areas. Plus, actually add extra detail that you otherwise couldn't enjoy. 

I think the only ini file that would be saved by the game would be SkyrimPrefs.ini and it would only happen on occasion. The mod itself doesn't save it; it merely is pointing out a vanilla game mechanic, mostly for saving Settings such as sound volume.

OT: As DY pointed out elsewhere, MO needs to write to SkyrimCustom.ini if you configure your MO profile to 'Use profile-specific Save Games'.

That must be right. Changes made by the mod are saved to the INI if a save of settings is triggered by something else (such as the user changing game options), but the mod itself doesn't trigger the save.

      Labyrinthian Shalidor's Maze Fixes by wSkeever
      Wiki Link
      This fixes a bunch of small layout glitches by repositioning objects and replacing meshes in the Shalidor's Maze area, and it adds sunlight.
      Install: if used with Assorted Mesh Fixes, they should overwrite it. There is an ESL plugin, which must be enabled.
      Conflicts: there is a minor conflict with Atlas Map Markers, which AMM wins using LOOT. It must be patched if sunlight is desired (see below). Otherwise no conflict with the current WIP STEP setup as far as I can tell.
      Before > After of one of the more noticeable fixes:

      Before > After of sunlight and shadows - only works if conflict with AMM is resolved:

      See Nexus page for more comparison screenshots.
