xray-16 VS dxwrapper

Since you are on linux, someone remade the engine and there is a native port of it https://github.com/OpenXRay/xray-16 It works with luxtorpeda if you have the game on steam or know how to add a non Steam game and give it the id of the game then choose luxtorpeda as a compatibility tool

Yes. It's a based on a fork from Open X-ray.

So knowing that I can play Stalker COP with the use of OpenXRay/xray-16, I started searching for Anomaly engine source code.

Here, Xray 1.6, no need for scammy links

In the future it may be worth checking out OpenXray too - https://github.com/OpenXRay/xray-16

Then, download this and place the files inside the game directory (C:\Program Files\Maxis\SimCity Classic).

There's also dxwrapper that implements old DirectDraw/3D interfaces with newer D3D9 api for better compatibility with newer Windows versions:

FYI: The Space Bar re-release features Elisha Riedlinger's DxWrapper (https://github.com/elishacloud/dxwrapper), whose config file is otherwise stock with just FullScreen enabled. I strongly believe they didn't properly test it.

RTX Remix uses a custom d3d9.dll though so you additionally need another wrapper such as https://github.com/elishacloud/dxwrapper to customize which dll should be loaded since by default d3d8to9 uses the default system file which will result in translated calls not being redirected to the path tracer used by Remix.

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).
