    Project2DFX is a set of plugins for GTA III, Vice City, San Andreas, GTA IV: The Complete Edition, GTA Liberty City Stories and GTA Vice City Stories, which adds LOD corona effect to a game map, making LOD-world look a lot better.

  • Project2DFX: What it does it that it lights up the city at far distances (https://github.com/ThirteenAG/III.VC.SA.IV.Project2DFX/releases/tag/gtaiv).

  • dxvk

    Vulkan-based implementation of D3D9, D3D10 and D3D11 for Linux / Wine

  • If you have a GPU that supports DXVK (Basically it forces DXVK to run the game in Vulkan intsead of it's usual DirectX 9, which the DX9 version hates GTA IV and while GTA IV hates DX9 back) and has more than 2GB of VRAM (DirectX Vulkan), then I HIGHLY recommend it: https://github.com/doitsujin/dxvk/releases (Use this guide to install it: http://ant-sh.blogspot.com/2020/07/gta-4-stutter-choppiness-fix.html. If you want aliasing AND DXVK, use this guide: http://ant-sh.blogspot.com/2021/01/antialiasing-with-dxvk-and-gta-iv.html. If your GPU doesn't support Vulkan, use DxWrapper: https://github.com/elishacloud/dxwrapper/releases).

  • WorkOS
