GTA 6 uses PSSR upscaling and advanced ray tracing on PS5 Pro
A PlayStation France product page briefly listed PS5 Pro feature blurbs for GTA 6 on November 4 (PSSR "AI-enhanced resolution" and "advanced ray tracing"), then vanished. Screenshotted by @Pirat_Nation and written up by PC Guide, GTA BOOM and eTeknix. One of the blurbs reportedly described a Ghost of Yōtei item, so the text may be a template error. Sony and Rockstar have confirmed only the "PS5 Pro Enhanced" label, with no PSSR, resolution or frame-rate targets.
