dhewm3 VS vkDOOM3

The installation is different from what you might be used to from your typical mod. Download dhewm3_1.5.2_win32.zip from the githup page, unzip it, then copy, as instructed by the WHAT_TO_DO.txt files in the base and d3xp directories of the unzipped mod the .pk4 files from the game directory over (d3xp is only there if you installed the Resurrection of Evil add-on first). You can then uninstall the game from Steam.

I played through it with dhewm3 recently. Really enjoyed it.

There is a source port of Doom 3 if you want to play it on Linux or macOS.

if you are going to play it on PC, then get the original 2004 release, with the dhewm3 source port since it can get to widescreen easily and is friendlier on modern devices.

Why do you want to run old, buggy code through wine when you could use native dhewm3 to play the original (non-BFG) version of doom3 with Bugfixes, OpenAL audio and proper widescreen support? https://dhewm3.org/

for me go for the original Doom 3 + dhewm3 source port since the source port can get to widescreen easily and is friendlier on modern devices. BFG Edition aint that bad but its very easy and lacking other content that the original Doom 3 had (especially ROE) and it has less enemy count.

For me, it was "I Am Graphics And So Can You" [1] series, where author progresses from the similar concepts up to a working renderer for DOOM 3, linked in the intro of this article [2].

Many of the vulkan presentations Kronos has given talk about this (especially the older ones), though they are also light on examples. Best specific example was the ID tech guys porting doom 3 to vulkan (I believe this may be the repo? https://github.com/DustinHLand/vkDOOM3) which they have given talks about

People can look at what's involved in the various game engines that have source available, for example this seems to be the Doom3/vkDoom3 collision detection code (UE5 has a bunch if you search for "collision"), and it's not simple to handle it. That was before (2004) nvidia even started trying to do hair/fabric as bleeding edge tech demos (geforce 5 or 6 IIRC)

I'm not a graphics programmer, but I've found these two resources to be illuminating: "How hard is Vulkan really? from GDC 2018", and id's comments in 2016 that Xbox does not use the same code paths as desktop D3D. The fellow giving the first presentation converted Doom 3 to Vulkan by himself as a starter project while on parental leave.

O3DE, the open-sourced version of Amazon Lumberyard, could, if for some reason id Tech 4 with Vulkan couldn't.
