Gillian's GTA IV Setup Utility

Semi-automatically installs DXVK and launch options for your GTA IV installation (+extra). It automatically checks your hardware and what options should be available (aswell as setting defaults).

This version is a re-write of the now-deprecated Python version.

Usage

• Launch the tool.
• Select your game folder, the one that includes GTAIV.exe.
• Press Install DXVK, after which, press Setup launch options.
• If experienced, play around with the toggles. Defaults should be fine, however, as they're automatically tailored to your hardware.
• Done!

Features

• Automatically installing the best version of DXVK supported by your hardware by checking it's Vulkan capabilities.
• Automatically sets up your launch options, including monitor details and VRAM (VRAM not available for versions older than 1.0.8.0; have to paste options manually on 1.2)
• Accounting for multi-GPU setups, both during DXVK setup and setting up the launch options.
• Detects whether some features are unsupported by your hardware.
• Detects if ZolikaPatch and/or FusionFix are installed and edits their configuration files to be compatible with eachother.
• Properly enables/disables Borderless Fullscreen if using ZolikaPatch or FusionFix
• Warns the user if they have IVSDK .NET and DXVK installed at the same time as RTSS is enabled.
• Providing tips for what the launch options actually do. And not providing useless options.

Contribution

Contribution is highly welcome. I'm poorly experienced with C#, but this rewrite was needed for many reasons. And so, the current code is extremely clunky and works out of prayers.

Attribution

Following NuGet packages were used to create this app:

• ByteSize by Omar Khudeira - used to calculate and convert the VRAM correctly.
• Microsoft-WindowsAPICodePack-Shell by rpastric, contre, dahall - allows to create a Choose File dialogue box.
• NLog by Jarek Kowalski, Kim Chriestensen, Julian Verdurmen - used for logging.
• SharpZipLib by ICSharpCode - used for extracting a .tar.gz archive provided by DXVK.
• And Microsoft's official packages such as System.Management for convenience and functional code.

And these were used during development:

• ini-parser by Ricardo Amores Harnandes - was used to edit ZolikaPatch and FusionFix ini files, replaced later due to issues with it.
