DOOM-3-BFG VS RBDOOM-3-BFG

The Bethesda representative said that they do not publish which OSS libraries they use but that they comply with any notice requirements. I admit, the claim on my side is somewhat thin, but there is one third party library (Base64.cpp) in DOOM 3 BFG that requires notice and states:

Even idTech 3 used third party components as listed in the description here: https://github.com/id-Software/DOOM-3-BFG. Newer versions of idTech use Vulkan for rendering. For that, they are basically forced to included the header files of Vulkan which are licensed under Apache 2. So it has to be mentioned somewhere.

I guess you can still write valuable software, even more complex than most people can write, with simple (03) C++. Like Doom 3: https://github.com/id-Software/DOOM-3-BFG

> What you are describing

On the other hand, I believe what you are describing is the exact meaning of FUD. In that precise order: "in C++ they have serious consequences" is fear, "There are bugs in the code--probably in your code--right now" is uncertainty, and "Some might be CVEs" is doubt.

According to https://github.com/id-Software/DOOM-3-BFG

Doom 3 was released in 2004. The engine has come to be known as "Id Tech 4", and it's open source. Written mostly in C++, looks like.

Id Tech 4 is currently Open Source (GPL licensed)

I believe doom 3 source is published on github so people can have a look for themselves if they want.

Doom 3 is a perennial favorite for "most beautiful C++ codebase" lists [0]

RBDoom3bfg, same thing, but for the BFG edition.

On the other hand BFG edition supports 120Hz rendering and has some great gamepad support. However the "shoulder lamp" and some tweaked brighter lighting destroys the game's atmosphere IMO while some textures and lights appear worse. I'd still recommend it if you liked the original game, but perhaps also play it with RBDoomBFG and its GI datapak - it introduced PBR shaders and changes the lighting considerably, but the game wasn't designed for that so i'd recommend it only for a second playthrough (you can disable most of the effects but even then it still looks off). The official BFG edition is closer to the original Doom 3 but still has its own issues so unless you want 120Hz rendering and/or gamepad support, i'd still recommend the original (with Dhewm3). Also note that the original BFG edition doesn't allow you to skip cutscenes which is annoying for a second playthrough.

BFG has better out of the box support, but both versions are open source and as such the community has made source ports for both of them to the point they are essentially equivalent and you only pick the one with the features you want the most, last time I played was using BFG because RBDOOM3 added support for PBR so the game isn't so absurdly dark but your mileage may vary and may prefer dhewm3's more faithful experience using the original release
