GTX 1660ti config

I thought I'd share my config file based on and as a high-end successor to my somewhat successful GTX 1050ti config. My .ini files are tailored for the GTX 1660ti GPU set to run the game on Ultra settings, with tweaked HBAO+ values, tweaked shadows, fixed sandboxing, ultra godrays fps loss and fake lights. My tweaks come with both a performance and visual fidelity increase. It is not a placebo, and these tweaks are well known and tested in the Bethesda modding community.

I have been modding various Bethesda games for over six years now, I understand that some of these tweaks might be trivial for seasonal users, but even then it can be convenient to have a drag and drop solution for veterans as well.

With this config my game runs perfectly at 60 fps with iPresentInterval (Vsync) enabled even in Boston inner city with the odd drops at my three identified "hot spots" (Namely: Garden terrace, Corvega assembly plant and USS Constitution).

It took me quite a while to figure out the perfect settings for my system, and this is the best performance to quality ratio I could come up with. It has no snake oil tweaks like ThreadedAI, only vanilla stuff and some tried and tested community approved tweaks. I currently run roughly 150 mods with this config and it plays nice without any stuttering/fps drops/crashing. If you don't have time to mess around with settings and ini tweaks then you can rely on this file, just drag and drop it and get playing/modding.

If you have any further questions about any particular tweaks or .ini settings just ask me in the comments.

Part 1: INI tweaks

My ini files now include a tweaked HBAO+ setup greatly increasing fidelity with no FPS loss. Texture streaming issues (stuck LOD) are also fixed. The Pip-boy display and power armor map are also fixed with .ini commands.

These are some of the added lines/tweaks in the config:

fDirShadowDistance=10000. 0000 - reduces shadow distance somewhat lower than High (High is 14000). I found that this is the biggest fps killer, and setting it to this amount doesn't produce any noticeable degradation in visuals. (for example Skyrim Special Edition which is an absolutely gorgeous game I run with a maxed out ENB has shadow distance set to 10000 on Ultra, and I never felt the need to increase it any higher)

fShadowDistance=10000. 0000

iDirShadowSplits=2

bEnableFileSelection=1 - enables modding basically

bInvalidateOlderFiles=1  - enables modding

sResourceDataDirsFinal=

SIntroSequence=0 - skips intro sequence simple as that.

iAutoSaveCount=16 - sets the max number of autosaves you can have, this is useful if you have a mod that enables autosave/save in survival mode
