GTA 6 targets 30 FPS on all consoles, PS5 features detailed
Rockstar confirms every current-gen console version of Grand Theft Auto VI will run at 30 frames per second, with PS5 touted as the platform where it plays best.

Rockstar Games has shared the first official performance details for Grand Theft Auto VI, confirming that the open-world title targets 30 frames per second across all current-generation hardware. Players on Xbox Series S, Xbox Series X, the standard PlayStation 5, and the PS5 Pro will all experience the same frame rate cap.
The developer stated that the game was built from the ground up to push the platforms to their absolute limits, prioritizing the density and visual fidelity of the new state of Leonida. While Rockstar has not yet published specific resolution targets, the PS5 Pro is expected to offer the highest image clarity thanks to PlayStation Spectral Super Resolution, along with ray-traced shadows.
A marketing arrangement between Rockstar and Sony appears to be in place. The studio declared that the game plays best on PlayStation 5 consoles, citing fully integrated haptic feedback on the DualSense controller, improved spatial audio rendering via Tempest 3D Audio, and improved load times that are likely a minimal advantage.
Xbox consoles retain one distinct feature at launch. The title will be available through Xbox Cloud Gaming for console players, though the streaming support does not appear to extend to PCs or mobile devices at release. Both platforms will support Remote Play, allowing players to cast the game from their console to another device.
