Modder opens GTA portals connecting SA to GTA 3 and Vice City

The boundaries of gaming reality are constantly being redefined by creative modders, and one recent project has managed to shatter those boundaries, allowing players to literally jump between different eras of Grand Theft Auto.

This incredible feat is the brainchild of creator Dryxio, who has engineered a system that places the worlds of San Andreas, Vice City, and GTA 3 into a unified digital space. It’s not just a simple graphical overlay; it’s a meticulously crafted experience where jumping between these iconic installments is entirely interactive and seamless.

The demonstration showcases how Dryxio opened portals from familiar locations in San Andreas, such as Grove Street, leading players directly into the environments of Vice City or other areas within the GTA multiverse. The magic lies in the interactivity: using an assault rifle, players can shoot through these portals, interacting with NPCs visible on the other side, treating them like ordinary windows.

Stepping through a portal means more than just changing scenery; it shifts the player’s perspective to that of another protagonist—whether they become Tommy Vercetti or Claude—allowing for continuous gameplay within each installment.

The technical architecture behind this digital mashup is genuinely astonishing. Instead of running these games as separate applications, Dryxio managed to execute all three titles simultaneously inside the same process, sharing a single Direct3D device.

To achieve this level of real-time synchronization, the portals aren’t mere videos or captured windows. Instead, they are dynamic live GPU textures, allowing the engine running the other games to seamlessly take control. The system intelligently swaps which engine is in charge while keeping all game states running in tandem, creating a perfectly synchronized experience.

This technical marvel highlights the depth of what modding can achieve when pushing computational limits. While this particular modification is not yet publicly available, it sets an incredibly high bar for future creative endeavors within the gaming community. Dryxio has already established himself as a force in this space, having previously developed tools like map editors and aesthetic filters that enhance classic game experiences.

The ability to bring these distinct gaming eras into a single, cohesive environment is a testament to innovation, proving that imagination, combined with clever engineering, can truly unlock new dimensions for interactive storytelling.
