Release 1.4.0

Changelog 1.4.0

• Fully integrates the Numos - Atmospheric Sky System which can be toggled via the F4 menu (see further down below)
• The updated Remix Runtime should help with the CPU Bottleneck. It does not fully fix it.

Remix Runtime:

• Rebased onto almost up-to-date version of the remix runtime
• A bunch Numos updates (by Remix Plus)
• Rasterized (original) Sky: fog now attenuates water reflections which blends the water and sky more nicely
• Fixed an issue where the sun/moon rendered twice
• Increased precision of distant light (sun) rotation - smoothing sun shadow movement
• Fixed emissive lamp flickering
• Fixed raindrops staying on translucent surfaces after it stopped raining

F4 Menu:

• Added a checkbox to quickly toggle between Physical Sky (Numos) and the Original Sky
• Added weather and time options to the Utility tab
• General F4 menu cleanup and slight restructuring
• Added an AntiCull toggle button to the Utility tab which disables all anti-culling tweaks. Useful if you want to take smaller remix captures
• Added a button to toggle a performance overlay showing a frame-graph, FPS and a stutter counter to the Utility tab

General:

• Fixed weather blending when using Numos
• Updated Numos weather presets
• Fixed dark rain particles
• Emissive surfaces now use vertex colors by default which now properly tint / dimm building lights and other emissive surfaces
• Changed on/off time for night time emissives to match game lights
• Updated DLSS + FG to 310.7.0 and tweaked bridge.conf
• Fixed invisible player / world on first spawn
• Added Discord Rich Presence - showing if player is on foot or in a vehicle + vehicle name and current area (and adds - RTX)
• Increased draw distance of roadside lights + volumetric strength (via new .img file in updates)
• More light tweaks and cleanup by Thundery_Dan
• Tweaked Commandline.txt and added tweaked stream.ini
• Limited game option sliders (Distance/Quality/Vehicle Density) to sane values. Can be disabled via the F4 menu
• Use 720p if initial resolution on first startup is below 720p - should fix first startup issues for some users
• Set GTAIV.exe to high priority on start
• Deleted unnecessary, loose Fusion Fix fork files
• Updated readme and credits

Installation:

Install using the installer:

1. Download GTAIV-Remix-CompatibilityMod-1.4.0.zip

2. Download GTAIV-Remix-CompMod-Installer.exe

3. Place both files in the same folder (no need to copy them to your game folder) and run GTAIV-Remix-CompMod-Installer.exe

4. Use the File Dialog to select your GTAIV.exe which is located in your GTAIV install folder

5. If this is your first time installing, the installer will ask if you want to install a custom Fork of FusionFix

   • Press YES - If you already have FusionFix installed, it's definitely recommended to install this because the original, unmodified version has a few incompatibilities with RTX Remix. If you do not have FusionFix installed, you are free to choose. It's not a requirement but highly recommended.

6. The installer will ask you if you want to download the required base-remix-mod.

   • Press YES - The CompMod will not function correctly without it - so make sure to install it.
   • Use the GIT install method (recommended) because its easier and faster to update to new versions (and uses less bandwidth)

7. The installer will ask you if you want to download the optional gta4-autopbr-mod.

   • This mod converts a bunch of game materials to approximated PBR-materials and makes the game less plasticy. It is entirely optional.

8. Make sure that you remove all custom launch arguments for GTAIV in Steam (if you have any set and use Steam to run the game)

Tip

You can re-run the installer at any time and choose to only check for remix-base-mod or AutoPBR updates.
If you've used the GIT installation method, it will do delta updates and pull the latest changes. The base mod is getting constant updates which are not coupled to Compatibility Mod releases.

OR Install manually (no need to do this if you've used the installer):

1. Download GTAIV-Remix-CompatibilityMod-1.4.0.zip

2. Open the zip and extract all files contained inside the GTAIV-Remix-CompatibilityMod folder into your GTAIV directory (next to the GTAIV.exe). Overwrite all when prompted.

3. If you want to use FusionFix or have it installed already, it's definitely recommended to install rtx-remix fork of it.
   You can find the files inside _installer_options/FusionFix_RTXRemixFork. Extract the plugins & update into your GTAIV directory and override any existing files.

4. Download gta4-rtx-base-mod

5. Extract the mods folder (inside of gta4-rtx-base-mod-master) into your rtx-remix folder so that the folder structure looks like this:

Edit: I've submitted the Installer to MS for manual review. If you get a false positive, download and use the Installer that shipped with 1.3.2: https://github.com/xoxor4d/gta4-rtx/releases/download/v1.3.2/GTAIV-Remix-CompMod-Installer.exe
