In this video, I show you how to install the new RTX Remix graphics mod in GTA 4 (2025). My goal here is simple: get you better lighting, cleaner shadows, and a much more modern look in Liberty City without confusing steps. I go through what you need first (the basic mods) and then how to set up RTX Remix properly so the game can actually load it and you can see the visual changes. I also share the main takeaway: RTX Remix is all about improving the overall visuals—especially lighting and shadows—so if you’ve been playing vanilla GTA IV, the difference feels like a proper remaster vibe. I’m running it on my setup (RTX 3060 + Ryzen 5 3500X + 32GB RAM), and this guide is made to keep the installation easy and beginner-friendly. If you follow the same order I use—basic mods first, RTX Remix after—you’ll avoid most of the common install mistakes and get the mod working faster.
