+### Reducing stuttering (Steam/Proton and Lutris/Wine)
+
+You may feel that the game stutters frequently during the first hour of play. This is normal, it's just DXVK having to compile shaders at draw time due not having a ready state cache. The more you play, the less stuttering there will be in the future.
+
+However if you don't want to wait you can try precompiled DXVK [_state cache_](https://github.com/doitsujin/dxvk#state-cache): [**Titanfall2.dxvk-cache**](https://github.com/begin-theadventure/dxvk-caches/blob/main/dxvk-caches/Titanfall/Titanfall%202/Titanfall2.dxvk-cache.md)
+
+Proton: extract and put it in `/path/to/steamapps/shadercache/1237970/DXVK_state_cache` default is `~/.local/share/..` or next to .exe if shader pre-caching is turned off.
+
+Wine: extract and put it next to game's .exe. Also remember to rename it if the .exe has a different name.
+
+There are also other (not necessary) tweaks as:

+_DXVK-_[_async_](https://github.com/Sporif/dxvk-async#improvements):
+
+Wine: download [**dxvk-async**](https://github.com/Sporif/dxvk-async/releases), extract and put it in `~/.local/share/lutris/runtime/dxvk` then type the name of the folder in `▲` ->  `Configure` -> `Runner Options` -> `DXVK version`, to enable add `DXVK_ASYNC 1` to `System Options` -> `Environment variables`

+Proton: can be used with [**Proton-GE**](https://github.com/GloriousEggroll/proton-ge-custom). Type `DXVK_ASYNC 1 %command%` under `Properties..` -> `LAUNCH OPTIONS`
