Wccftech first reported the September 17 release, timed to the 13th anniversary of Grand Theft Auto V’s original September 17, 2013 launch. Razed’s public NaturalVision pages and the Cfx Marketplace listing independently confirm that NaturalVision Enhanced is a free visual overhaul for GTA V Enhanced designed to use its ray-tracing features, but they did not yet expose a dated September 17 changelog when checked. That leaves the extensive item-by-item claims — including real moon phases, upgraded emergency-light shadows, and map-wide LOD-light changes — attributed to Wccftech’s reporting and Razed’s release material rather than independently benchmarked results.
The update is nevertheless a useful marker for PC graphics modding. Rockstar’s Enhanced edition gave GTA V a ray-tracing baseline that its older PC release did not have, while NaturalVision Enhanced can now concentrate on how the game uses that lighting rather than attempting to simulate every effect through post-processing alone.
The key upgrade is more than a prettier night mode
Razed’s reported changes center on ray-traced global illumination, directional lighting, vehicle shading, contact shadows, and sky lighting. The stated addition of more ray-traced light bounce matters because indirect illumination is what prevents a scene from looking like it is lit only by a handful of visible lamps. It affects the color and brightness of shaded streets, interiors, underpasses, vehicles, and foliage — details screenshots often hide until a player starts moving through a scene.
GTA V Enhanced already added PC ray-tracing options, including ray-traced global illumination and reflections. RockstarIntel reported in June 2025 that Rockstar subsequently exposed settings for a second RTGI bounce and higher-resolution ray-traced reflections. NaturalVision Enhanced therefore has a more capable engine base than graphics mods built for GTA V Legacy, but that also means the mod’s visual gains stack on top of a rendering mode that is already among the heaviest in the game.
The update’s most credible visual payoff is likely to be in motion and at night rather than in static daytime comparisons. Retroreflective road signs and lane markings, improved siren illumination, stronger vehicle paint response, and revised LOD lights should make Los Santos’ roads read more naturally under headlights and emergency lighting. Those are incremental features individually, but they address the visual discontinuities that make an old game look old: a bright lamp with no believable spill, a sign that stays flat under headlights, or a distant city light that pops in rather than fading into view.
Moon phases and weather effects are simulation details, not a new renderer
The headline detail is the claim that the mod now uses real moon phases and improved moonlight, with rays and better interaction across surfaces and vehicles. It is an unusual feature for a GTA V visual package, but players should calibrate expectations. A physically modeled lunar cycle will change the appearance and timing of night scenes; it does not mean Los Santos is receiving astronomy-grade environmental simulation.
The more consequential additions may be the stated changes to water and weather. Wccftech reports upgraded underwater lighting, rain ripples on ocean water, subsurface scattering, more natural waves, and reworked volumetric clouds that reflect across surfaces. Subsurface scattering is a rendering method used to imitate the way light penetrates and diffuses through materials such as water, skin, leaves, wax, or thin fabric. In a game with bright coastal daylight and long sunset hours, that can improve the transition between opaque water, shallow water, foam, wet pavement, and vegetation.
Previous NaturalVision Enhanced releases show this work has been progressing in stages rather than arriving as a single rewrite. DSOGaming covered a May 2026 update that added physically based sky scattering, revised water shaders, altered vehicle paint shading, rain effects, and ray-traced mirror reflections for more than 70 stock vehicles. Razed’s own public Patreon page also lists a May update for both Enhanced and Evolved. The September update should be read as another pass on that technical direction, not the debut of NaturalVision Enhanced itself.
That distinction corrects a fuzzy part of the anniversary framing. NaturalVision Enhanced had been publicly available for GTA V Enhanced since 2025; September 17’s reported release is an update to an existing project. For players who already installed it, the immediate question is whether Razed provides a clean update path or requires removal of prior components. The public material reviewed for this story did not spell that out.
Enhanced and Legacy remain different mod targets
The version name is not cosmetic. NaturalVision Enhanced is for GTA V Enhanced, Rockstar’s newer PC edition, while NaturalVision Evolved remains the parallel project for GTA V Legacy. Installing the wrong package is an easy way to turn a visual upgrade into missing assets, incompatible plugins, broken shaders, or a game that will not launch.
Razed’s documentation describes NaturalVision as a project that changes game files, shaders, models, and textures without official development tools. Its Legacy installation guidance calls for a clean game folder, OpenIV, Script Hook V, and installation through a mods folder. It also notes that volumetric-cloud options can reduce frame rates and that optional performance settings trade lighting effects and draw distance for better performance.
That documentation is specifically for Evolved and should not be mistaken for a verified installation guide for the September Enhanced update. Still, it captures the operational reality that applies to any substantial GTA V graphics mod: installation is file-level modification, not a harmless preset toggle. Keep a backup or a separate copy of the game, document every modded file, and verify the exact game build supported by the release notes before updating.
The Cfx Marketplace product page labels NaturalVision Enhanced as a free GTAV Single Player package. Players should take that label literally. Do not assume compatibility with GTA Online, do not install it into a directory used for Online play, and do not expect anti-cheat restrictions to be irrelevant merely because the mod is visual. Razed’s Legacy documentation instructs users to disable BattlEye to run mods, which is a clear signal to isolate modded single-player use from an Online configuration.
HDR does not automatically mean a correct HDR image
The claimed addition of HDR support is potentially significant for Windows PC users with an HDR-capable display, but it is also the feature most likely to disappoint if the entire display chain is not configured correctly. HDR in a mod can mean anything from revised tone mapping to a real HDR output path, and the submitted release description does not identify supported display standards, Windows requirements, in-game calibration controls, peak-brightness behavior, or whether the feature expects the game’s own HDR settings to be enabled.
Until Razed publishes those details, users should not treat “HDR support” as proof of reference-quality HDR. A display set to HDR mode can make poorly mapped content look washed out, overly dim, or aggressively clipped in highlights. Screenshots are especially poor evidence here because most standard image-sharing workflows convert or tone-map HDR material back to SDR.
The safer approach is to establish a stable SDR baseline first: use the correct Enhanced build, confirm that ray tracing is working, and record frame rate and GPU memory usage in a consistent scene. Then enable HDR and any high-cost NaturalVision options one at a time. The specific combinations most likely to move performance are RTGI bounce count, high-resolution ray-traced reflections, volumetric clouds, water effects, resolution, and upscaling mode.
What PC players should expect from this release
NaturalVision Enhanced is a demonstration of why GTA V Enhanced matters on PC. A modder can now build around native ray-tracing hooks, then spend effort on material response, sky behavior, shadow quality, rain, fog, bloom, and local lighting instead of relying entirely on screen-space tricks. The mod’s reported heat haze, parallax road surfaces, physical street lighting, and upgraded character lighting are all attempts to make an aging world feel coherent under a modern lighting model.
But the release does not change the basic cost of that approach. Ray tracing is expensive, and a graphics mod that adds more lighting layers, volumetric effects, higher-quality reflections, and complex water shaders will not produce the same result on every PC. The public release material does not provide a GPU tier, VRAM target, tested resolutions, or a performance comparison against unmodded GTA V Enhanced. Anyone presenting it as a free visual upgrade with no hardware consequence is leaving out the one number most players need.
For GTA V Enhanced owners willing to maintain a dedicated single-player installation, the update looks like a substantial continuation of Razed’s work rather than a novelty anniversary patch. The immediate consequence is straightforward: expect Los Santos to demand more from the GPU in exchange for lighting and weather details Rockstar’s own Enhanced edition leaves on the table.
