Ak sa na obale hry nachádza štítok Optimized for Xbox Series X, znamená to, že hra využíva schopnosti hardvéru Xbox Series X, ktoré by neboli dostupné na Xbox One X alebo starších. Microsoft stanovil rozlíšenie 4K ako štandard v prípade Xbox Series X, rozlíšenie 1440p v prípade Xbox Series S. Za štandardné snímkovanie sa v prípade oboch konzol pokladá 60fps, vo výnimočných prípadoch môže byť nižšie (30fps) alebo až dvojnásobné (120fps).
Hry optimalizované pre konzoly Xbox Series X|S môžu takisto podporovať funkcie ako DirectX Ray Tracing, ktorý dodáva väčšiu živosť do grafiky aj zvuku. Už budúci rok (2021) budú hry môcť podporovať nielen zvukový štandard Dolby Atmos, ale aj obraz s vyšším rozsahom farieb Dolby Vision.
Viaceré z hier takisto podporujú funkciu Smart Delivery. Vďaka nej si stačí len raz kúpiť hru, a po vložení disku do mechaniky systém sám rozpozná, či má inštalovať verziu pre Xbox One alebo Xbox Series X. Netreba tak nakupovať dve rôzne verzie hier pre dve rôzne generácie konzol. Platí to však len pri hrách, ktoré sa rozhodnú túto funkciu využívať – napríklad Call of Duty: Black Ops Cold War ju nepodporuje.
V prípade hier zo spätnej kompatibility môžu hráči na oboch konzolách očakávať rýchlejšie načítavanie a automatické HDR, či funkciu Quick Resume, s ktorou je možné mať spustených na pozadí viacero hier naraz. V prípade Xbox Series X budú hry, ktoré sa dočkali vylepšení pre konzolu Xbox One X (2017–2020), podporovať aj vylepšenia z tejto konzoly. Xbox Series S bude podporovať iba verzie hier vyvinuté pre Xbox One (2013–2016) a Xbox One S (2016–trvá)
