Additional Comments

* The issue with blank books/notes does not appear for everyone.  Discussion on the Proton issue tracker suggests that it might be related to drivers and/or GPU.

• Go to your home folder and open "Documents"->"My Games"->"Skyrim"

• Open the "SkyrimPrefs.ini" file.

• Find the lines where you see "bFull Screen", "iSize H" and "iSize W"
  and change their values to your desired resolution.

This method is experimental presently(see associated bugs), so try at your own behest.

1. Install enb same way as in windows to game directory
2. Open `winecfg` and under libraries add "d3d9" and set it to "Native then builtin".
3. To set basic enb environment, run `winetricks --showbroken d3dcompiler_43`
4. Additional dll requirements change depending on the preset used, `winetricks d3dx9_43 d3dx9_36` should work fine for most presets.
   
5. Experiment with more dlls to get your preset working but avoid installing directx9, d3dx9_42 and d3d9 as they would do more harm then good.

Game getting stuck at load screen (Vivid Weathers ENB)

• This is caused by enbeffect.fx and enbeffect.fx.ini files, I replaced these with the one from Tetrachromatic ENB Ghost Preset to make it work.

Game getting stuck after/during load screen, ingame music keeps running(Multiple ENB Presets)

• Set `FixParallaxTerrain=false` in enblocal.ini

There is a black overlay over characters and objects(Tetrachromatic ENB Ghost Preset)

• This is a issue in subsurface scattering, set`EnableSubSurfaceScattering=false` in enbseries.ini to solve this. 
• Surprisingly, enabling ambient occlusion also corrects this, only set `EnableAmbientOcclusion=true` in enbseries.ini to have both ambient occlusion ans subsurface scattering working without issues.

Everything is black with only hud visible

• Set `FixTintGamma=false` in enblocal.ini

Audio

To fix crackling and choppy sound with Pulseaudio:

Possible fix 0:
run in some terminal:
while true; do pasuspender sleep 0.02; sleep 60; done
This finally prevents buffer underruns and the sound is perfect then.

Possible fix 1:
Make sure your realtime kit (rt-kit) is installed and functional so it can assign pulseaudio realtime priority. The kernel config CONFIG_RT_GROUP_SCHED needs to be off for this (see here).

Possible fix 2:
Setting SndQueueMax to 15 (default is 10), see here:
wiki.winehq.org/UsefulRegistryKeys

Possible fix 3:
Launch wine with an environment variable set:
PULSE_LATENCY_MSEC=50 wine steam.exe

Underwater view

If you cannot see underwater (water is solid green):
Edit SkyrimPrefs.ini in your 'My Games\Skyrim' directory and in the [Imagespace] section set bDoDepthOfField=0 and iRadialBlurLevel=0

This is a game bug, not a Wine issue!

Stuck at main screen

Some mods change the fonts in Skyrim and sometimes that ends in wine not showing up the menu of Skyrim. Simple fix is to remove fontconfig.txt in Data/Interface.

Remember, this is a Bethesda game, a few bugs happen for Windows users too, so blaming wine might not be justified. Please leave comments and bug reports, especially if things that used to work suddenly break.
