# [Bigscreen Beyond Driver](https://steamdb.info/app/2467050/)
You can get the "Bigscreen Beyond Driver" app from Steam working via Proton by following these instructions:
1. use a Proton version >=10 that has access to `PROTON_ENABLE_HIDRAW` env var; `Proton Experimental [bleeding-edge]` works well
2. set `PROTON_ENABLE_HIDRAW=0x35BD/0x0101 %command%` as your launch arg for the `Bigscreen Beyond Driver` under `Properties`
3. OPTIONAL: download/copy a SteamVR Windows install somewhere and when the driver is open, set the SteamVR path to where you placed the Windows install of SteamVR
The "Bigscreen Beyond Driver" and most of its features should be working fine after doing the above!
Note that currently firmware updates do not work.
## Download Windows SteamVR via SteamCMD
You can easily downlwad the Windows version of SteamVR via SteamCMD. To do this:
1. [Download SteamCMD](https://developer.valvesoftware.com/wiki/SteamCMD#Linux)
2. Run this command somewhere you can create directories (i.e., your home directory):
```sh
mkdir steamvr_win && steamcmd +@ShutdownOnFailedCommand 1 \
+@sSteamCmdForcePlatformType windows \
+force_install_dir $(realpath steamvr_win) \
+login anonymous \
+app_update 250820 validate \
+quit
```
This will:
- Create a directory in the current directory named `steamvr_win`
- Download and validate Windows SteamVR into it.
Note: your home directory is accessible under `Z:\home` by default in Proton.
## Easier Device Mode Swapping
You can also swap modes more easily without using the "Bigscreen Beyond Driver" if your device is set to 75hz mode via `XRT_COMPOSITOR_DESIRED_MODE` for an Enivison profile.
1. `XRT_COMPOSITOR_DESIRED_MODE=0` is the 75hz mode
2. `XRT_COMPOSITOR_DESIRED_MODE=1` is the 90hz mode
You can verify which modes are which by using a tool like `xrandr` with the HMD plugged in. The top two modes are the relevant ones used here and are listed in order, starting at an index of 0.
