So, my personal experience of the installation is been a bit complicated by the tutorials i’ve find on YT. Basically I was stuck in the part where after the installation you need to change the directory (or add a new shortcut) for the launcher. Many video didn’t explain that or use a previous version of the OS with slightly different interface. In the end i’ve found this great tutorial online and completed everything.

There is anything i should do (both on the device setting or in the Ubisoft setting) to improve the experience on my Steam Deck?

Btw. The download of the game (AC Origin) was superslow (9mb/s). Any way to fix that?
