ultimately its going to be a game of price to performance. Valves money into arm compatibility due to the steam frame helps with driver support, but ultimately whether arm for linux actually takes off for pc games solely relies on supporting the drivers for each major entry into the arm options.

also cant really trust nvidia to do it as much so dont expect the largest push to be based on the spark option. what it does is allow ayaneo and ayns to run linux instead of android for some of their devices
