An Open-Source Doom 3 Engine Is Looking To Implement Vulkan Support

I played the game on my laptop, with a AMD A8 trinity, the bottleneck was the cpu on my pc (I know because of the rage benchmark) not the IO, because I have an SSD, maybe you used a hhd. Well I'm not very sure anyway.

Anyone who uses a SSD is quite fine. If you use a HDD the game chugs, no matter what GPU you use. That was my point. What frustrated me was that the game never took advantage of x64 ie, larger amounts of RAM. Ram is faster than an SSD. So the game devs had no excuse for it's hdd caching issues.

Well to be honest, my 780 GTX kind of did an average job with Rage. I have a friend who has an AMD GPU and it runs better on his system simply because he uses a SSD as his gaming drive. The game has limitations more with drive load I/O than with GPU. Before I had the 780 GTX, my old 460 GTX ran the game fine. I finished the game using the 460 GTX and by the time I upgraded, I had lost interest in the game because it was too short.

I liked the game, you can play it with wine. It won't run 2x faster because it has an adaptive loading technology for texture loading that keeps the fps at 60. You can only tast how good your pc is at unpacking/decompressing the textures, unfortunatly it's accelerated only with cuda, so Intel and Amd harware do have bad performance, also true on Windows.

There may be a point in the long run. DOOM 3 is a classic that will probably be played for long. Just like 3dfx died, opengl may die one day. Not tomorrow, but it may. Having a more modern API, even if it doesn't provide better performance, may help avoiding the need of emulation.

It is quite unlikely that workstation programs and 3D DCCs like Blender will switch to Vulkan, Khronos seems to say that OpenGL still has uses in many cases (like, for beginner programmers), too.

I had assumed it was just being done because it was a really cool thing to do

Would be nice with Vulkan and Wayland support.

Is there any point of this? Based on what croteam, Valve, RSI have said you need to properly refactor your engine to really get the benefit of Vulkan/ DX12. Do they have the resources to do that?

They'll probably wrap the whole thing in Vulkan translation layer, just like Croteam did (as a first step towards migration) with Talos Principle. A nice exercise you want to learn a thing of two about Vulkan and also something that looks good on a resume.

BFG Doom is not old and huge fun to play natively instead of using wine. Vulkan support would be way cool but hey how about SteamVR support. This game must be truly creepy in VR.

I loved to play RBDOOM-3-BFG natively and not with wine. BFG doom is not old and a Vulkan port would be way cool. How about SteamVR support? Hey man
that must be a shuddering experience...
