Proper Shaders Modernizes GTA San Andreas with Deferred Rendering

Published on May 14, 2026 | Translated from Spanish

The Proper Shaders mod, created by Junior_Djjr, transforms the lighting system of GTA San Andreas without relying on external filters like ReShade. Its new version introduces a complete deferred rendering pipeline, per-pixel lighting, and advanced dynamic shadows. This allows for the efficient management of hundreds of lights, completely renewing the visual appearance of Rockstar's classic.

A renewed night scene from GTA San Andreas: wet streets reflect neon lights and car headlights, with sharp dynamic shadows on textured buildings, under a dark sky without external filters.

Per-pixel lighting and shadows with Gaussian blur 🌟

The update incorporates volumetric light beams and ambient occlusion using SSAO and HBAO techniques. Shadows are smoothed with Gaussian blur, eliminating hard edges. Procedural texturing adds detail to surfaces without needing to manually replace textures. All of this works within the original engine, without external graphics patches, proving there is still room to squeeze performance out of the 2004 code.

Now CJ can see his own shadow without using a mirror 😂

The best part is that this mod doesn't require a quantum PC. While other modern games ask you to sell a kidney to see soft shadows, here you can achieve similar effects with hardware from a decade ago. Sure, your fan will spin like a helicopter taking off, but at least San Andreas no longer looks like a cardboard mockup lit by camping lanterns.
