First Update For Grand Theft Auto 4 RTX Remix Released

Leave a comment

Modder ‘xoxor4d’ has released the first update for his amazing RTX Remix Path Tracing Mod for Grand Theft Auto 4. So, let’s see what this first patch brings to the table.

For those who did not know, this RTX Remix enables real-time Path Tracing in GTA 4. This is a must-have mod for everyone who has a high-end GPU and wants to replay this classic GTA title.

The first patch fixes several visual problems. It removes strange visual glitches that appeared in front of glowing surfaces. It also fixes texture issues on the back lights of vehicles, which were caused by a blending problem.

Some bright white surfaces were missing their proper colors, and those are now corrected. Vehicle windows will now look clear and transparent by default, even without special settings. Also, the V-shaped sirens on police cars will finally show real spinning lights, just as they should.

This first update also adds a new option that stops certain indoor objects from disappearing when they shouldn’t. For example, Nico’s bedside lamp will now stay visible.

Glowing surfaces can now use UV animations, which means they can have simple moving light effects. The update also fixes the see-through funfair stairs and makes some glass textures properly transparent.

On top of that, rain has been added using a new particle system that follows the player around the map. There are now four types of rain: heavy rain and light rain for both day and night.

Those interested can download and install the update from the GitHub of GTA 4 RTX Remix.

I also recommend downloading this HD Texture Pack for GTA 4 RTX Remix. This mod will enhance a lot of the game’s low-quality textures. Right now, it does not cover the entire game. Still, it can make your game look way better than before. You can find a showcase video a couple of paragraphs below.

As I’ve said, this RTX Remix Path Tracing Mod can also be used to enjoy Vice City. You can do this by installing the Grand Theft Auto: Vice City Nextgen Edition Mod. Grand Theft Auto: Vice City Nextgen Edition is a free remaster of the classic GTA game. This project brought all the missions, the whole map, and content from the original game to the RAGE Engine.

Finally, you can find below the entire changelog for this first update of GTA 4 RTX Remix.

Stay tuned for more!
