## Requirements

- bottles
- winetricks

## Steps

* create a new 32-bit bottles with any wine runner. wait for set up to finish.
* create a standalone by running `flatpak run --command=bottles-cli com.usebottles.bottles standalone -b [bottle name]`.
* run `source [bottle path, printed by the previous command]/standalone`.
* install deps with winetricks. `winetricks vcrun2005 dotnet48 corefonts`.
* configure the bottle.
  * enable DXVK in bottles. Sims 3 bottle > Settings > DXVK, pick any version.
  * enable the wayland driver if needed. `HKEY_CURRENT_USER > Software > Wine > Drivers`, new string value `Graphics` with the value `wayland,x11`.
  * set DPI if you're using fractional scaling. Settings > Advanced Display Settings > Screen Scaling. `96 * 1.25` (for 125%)
* install the game using the installer.

## Caveats

### game crashes on launch with no errors.

this is an issue with new Alder Lake+ CPUs from Intel. 
to fix, you must install this patch: https://modthesims.info/d/667734/intel-alder-lake-patch.html. 
don't forget to move all installer files into the prefix or it won't launch.

### high GPU usage

this is an issue with DXVK. the game can be installed and run without DXVK using wined3d, 
but on the wayland driver there's a problem with low gamma.

can be worked around by setting the following dxvk config (from here [github.com](https://github.com/doitsujin/dxvk/issues/4893):

```
d3d9.textureMemory = 1
d3d9.presentInterval = 1
d3d9.maxFrameRate = 60
d3d9.samplerAnisotropy = 16
```

to apply, create a file in the root of the bottle (where `drive_c` is), 
and in Settings > Environment Variables set `DXVK_CONFIG_FILE=` to the path to the file. 

what also can help is `dxvk-gplasync-v2.7-1`. after switching add `dxvk.enableAsync=true` to the dxvk config. 

### poor performance/stutters

this seems to be related to unroutable sims. to fix, install [nraas Overwatch](https://www.nraas.net/community/Overwatch). 
[nraas ErrorTrap](https://www.nraas.net/community/ErrorTrap) and [ld's Smooth Patch](https://modthesims.info/d/658759) are also a nice addition.

### can't launch the game due to "updates"

this happens on new wine builds (10.12+?) when using the Launcher 
and can be bypassed by launching the game directly via TS3(W).exe
