A game issue in Elden Ring's case specifically. It suffered from bad shader compilation stutters (even up to 900ms in the initial area). Valve solved the issue on Steam Deck by distributing a precompiled shader cache with the game.

Shader compilation issues is another way of saying driver issues.

Other games running on same hardware and same drivers go around it one way or another.

Yes but Microsoft isn't fixing it, valve is. Support changes quality.
