Grand Theft Auto 5's PC RT enhancements hint at GTA 6 features

GTA 5 PC adds RT upgrades showing potential GTA 6 features, focusing on ray traced global illumination.

: Grand Theft Auto 5 on PC receives ray tracing upgrades, showcasing upcoming Grand Theft Auto 6 potential tech features. Ray traced global illumination significantly enhances visuals, transforming open-world lighting and shadows. These upgrades include RT reflections and complex BVH structures indicative of GTA 6 technologies. Optimizations hint these lighting features may be leveraged effectively in next-gen console systems.

Grand Theft Auto 5's PC version has incorporated Ray Tracing (RT) enhancements, comparable to current-generation console counterparts after nearly three years, hinting at prospective features of GTA 6. These upgrades, including ray traced global illumination (RTGI) and reflections, address lighting inconsistencies noted in older versions. Adrian Courrèges previously highlighted lighting management through real-time cubemaps similar to techniques in racing games, an underlying weakness remedied by more advanced RT features now available on PC.

Alex Battaglia, a video producer from Digital Foundry, describes the RT update as a transformative enhancement for GTA 5 PC, a game originally developed for Xbox 360 and PlayStation 3 architecture. Despite limitations due to its age, RTGI provides a major change, especially via bounce lighting significantly improving environmental detail and mood. What makes these changes notable is their selective material application, increasing computational demand with detailed BVH structures beyond console capabilities.

Battaglia suggests that work on these RT updates likely serves as technology previews for Grand Theft Auto 6, demonstrated in earlier trailers. This inference arises from the observation of comprehensive per-pixel RTGI that handles numerous light sources efficiently. Though typically such full-fledged ray tracing implementations are sparingly used in older games, Rockstar's investment in this aspect hints at ongoing refinement for GTA 6.

Performance tests using an NVIDIA RTX 4060 at 1440p in DLSS 3 quality mode with ultra RTGI and reflections indicate a steady 60fps, a promising sign for how this refined RT could balance visual fidelity and computational load in upcoming releases. Nonetheless, challenges remain as CPU limitations constrain such RT features achieving higher frame rates, emphasizing a potential focus on 30fps targets for consoles.

Despite attention to detail, particularly in managing textures and lighting effects, some aspects like light bounces in GTA 5 RTGI may see further optimization in GTA 6 using more modern techniques. These enhancements offer a glimpse into Rockstar's potential exploration of technology that could fortify the gaming experience without majorly hindering performance, hinting at the ambitious objectives for the next big release.
