Release Day 2022.6.28

today is

Release Day!

It’s Release Day again!

Two more weeks of work have been done and it’s time to celebrate another release day!

This release brings many new features, performance improvements and bug fixes.


Ok now let’s get to the point. What’s new in this version?

Steam Proton Prefixes

After months, support for Steam Proton prefixes is finally available!

This new feature allows you to manage Proton prefixes created by Steam. This kind of prefix is not a common Wine prefix, it explicitly requires Proton and other arrangements. Once you enable support and restart Bottles, you will notice a new section in the bottles list, here all your Steam games running through Proton will appear. Clicking on one of these will take you to a limited bottle view that allows you to manage some features and settings of the prefix.

The game linked to the prefix is shown in the program list and instead of the play/stop button we are used to, there is a button to start it via Steam.

As mentioned above, this is limited prefix management since some features are entirely handled by Proton and/or Steam and altering them can cause irreparable problems. For example, it is not possible to change the runner, Bottles automatically identifies the version of Proton used by the prefix and every operation is performed using that.

The bottle generated by Bottles to handle this kind of prefix are temporary, meaning that it is recreated each time it is started. This one unlike the other bottles, consists of only the configuration file that is generated by parsing the launch options set on Steam. This choice was made to preserve consistency between Bottles and Steam, preventing the user from making changes that will be lost with the next boot.

Nowadays, it is not possible to apply changes to Steam’s launch options while it is running, which is why you need to restart Steam to apply them.

If you wish to try this feature and use Bottles’ Flatpak, remember to give Bottles the permissions to reach the Steam installation path and any external Steam libraries if configured.

We have many other plans for this feature in the near future e.g. allow changing the version of Proton (e.g. GE-Proton).

Although this feature has been tested for a long time, there may be bugs. Be sure to report them on our GitHub repository.

Epic Games Store Integration

With the previous version we began to implement a number of integrations with some software installed in the bottle. After Steam we moved on to Epic Games Store, once the feature is enabled just reload the programs screen of the bottle to list all the games that have been installed through Epic Games Store.

Unlike the integration with Steam, launching a game does not launch via Epic Games Store, as we have not been able to get positive results with the official method which, as of today, seems not to work anymore (we have feedback from other managers as well), we are working on a solution.

New Per Program Overrides

We have added new possibilities for overriding bottle settings per program.

These, as the title says, are program-related settings that override those set in the bottle, for example we can have DXVK active in the bottle and set an override to avoid using it with a program.

The following new overrides can now be set:

  • Current Working Directory
  • FSR
  • PulseAudio Latency
  • Virtual Desktop

EasyAntiCheat and Battleye Support

Our runtime has been updated and now provides the libraries needed to run EAC and Battleye, the two popular anticheats. Obviously the game developers must have enabled Linux support to run and the runner must support these (Caffe 7.10-1 has been updated with the necessary patches).

Although these have been implemented along the lines of the Steam implementation, they may not work properly and we ask that you report anomalies in our GitHub. It is important to point out that we as Valve itself, are not responsible for any bans.

Repository Update Feedback

Bottles on startup downloads the updated version of its repositories (about 20kb), which are essential for Bottles to function properly. For transparency we decided to include a small note in the loading view.

These repositories are essential and we are looking for a way to cache that does not prevent the user from receiving important updates.

Add Programs with bottles-cli

We have added a new option to bottles-cli which allows you to add programs to a bottle.

Check the following syntax:

❯ flatpak run --command="bottles-cli" com.usebottles.bottles add --help                            
usage: bottles-cli add [-h] -b BOTTLE -n NAME -p PATH [-l LAUNCH_OPTIONS] [--no-dxvk] [--no-vkd3d]

optional arguments:
  -h, --help            show this help message and exit
  -b BOTTLE, --bottle BOTTLE
                        Bottle name
  -n NAME, --name NAME  Program name
  -p PATH, --path PATH  Program path
  -l LAUNCH_OPTIONS, --launch-options LAUNCH_OPTIONS
                        Program launch options
  --no-dxvk             Disable DXVK for the program
  --no-vkd3d            Disable VKD3D for the program
  --no-dxvk-nvapi       Disable DXVK Nvapi for the program

This new option can be useful to third party programs for better integrating with Bottles.
