Grand Theft Auto 4 RTX Remix Path Tracing V1.4.0 Released

Leave a comment

Modder ‘xoxor4d’ has released Update 1.4.0 of his amazing RTX Remix Path Tracing Mod for Grand Theft Auto 4. So, let’s see what this new version brings to the table.

Update 1.4.0 fully integrates the Numos – Atmospheric Sky System to the game. Players can enable it via the F4 menu. For those who don’t know, Numos is a special version that incorporates a physical atmosphere, volumetric clouds, and a new weather system. This version can change the game’s art style. The good news is that this is optional. So, if you don’t like the visual changes it makes, you can stick to the original version.

Moreover, Update 1.4.0 features the latest Remix Runtime, which should help with the CPU Bottleneck. As such, the game should now run a bit faster on your PC. Still, this latest version does not fully fix the CPU optimization issues.

Version 1.4.0 also improves the game’s lighting. The update increases the draw distance for roadside lights and makes volumetric lighting stronger. Emissive surfaces now use vertex colors by default. This lets building lights and other glowing surfaces display the correct color and brightness. The update also changes when lights turn on and off at night so they better match the game’s lighting system. On top of that, it includes several other lighting improvements.

And that’s not all. Thanks to the new Remix Runtime, raindrops will no longer stay on translucent surfaces after it stops raining. The New Remix Runtime fixes an issue where the sun/moon was rendered twice, and it fixes emissive lamp flickering. It also increases the precision of distant light (sun) rotation. As such, you’ll now have a smoother sun shadow movement.

You can go ahead and download the latest version of this RTX Remix Mod from here. I also recommend using the HD Texture Packs we’ve shared for it. You can download them from here, here, and here. At the end of the article, you can also find the complete changelog for Version 1.4.0.

If you want to play older games with Path Tracing, you should try these mods. For instance, you can find such mods for Black Mesa, Star Wars Republic Commando, Need for Speed Carbon, NFS: Underground, and Manhunt. You can also find more for BioShock, Morrowind, NFS: Underground 2, Star Wars Jedi Outcast, and Vampire: The Masquerade – Bloodlines.

And that’s not all. Modders have released demos for their Path Tracing Mods for Deus Ex, Mirror’s Edge, and Tomb Raider. And then we have the RTX Remix Mods for Painkiller and Left 4 Dead 2. Unreal Tournament 2004 and Unreal Gold have also gotten the path-traced treatment. Half-Life fans can also play the game with Full Ray Tracing/Path Tracing. A demo has also come out for a Path Tracing Mod for Duke Nukem 3D. Then we have the beta release of the Dark Souls 2 Path Tracing Mod. Lastly, you can download these amazing Path Tracing Mods for Doom, Doom 2, Quake, and Serious Sam. These last ones are among the best Path Tracing Mods you can find. So, don’t skip on them.

Have fun!
