GTA 6 is targeting 30 frames per second, supports ray tracing on the PS5 Pro, and will run on Xbox One through Xbox Cloud Gaming.
Frames per second is how many images a game draws each second. At 30, that is half the 60 fps many console games offer as a performance option. Ray tracing is a lighting technique that simulates how light bounces off surfaces, which produces more realistic reflections and shadows and takes a lot of processing power. The PS5 Pro is Sony's upgraded version of the PS5.
Xbox Cloud Gaming works differently from a normal install. The game runs on remote servers and the console receives a video stream, so the Xbox One, a 2013 design, only has to play back video rather than render the game itself.
Putting a 30 fps target next to ray tracing is a familiar console trade. Studios often spend hardware headroom on how a game looks instead of how fast it updates, and a sprawling open-world game is a natural candidate for that choice. The streaming route also gives the oldest Xbox in the family a way in that does not depend on its own chip.
What ray tracing covers on the PS5 Pro, whether reflections, shadows or something else, is still an open question.
