RBDOOM-3-BFG 1.5.0 replaces OpenGL with DX12, almost doubling performance

The modding team behind RBDOOM-3-BFG has released a new version of it that replaces OpenGL with DirectX 12 and Vulkan. According to the team, and in some really demanding scenes, DX12 can almost double the game’s performance.

As the team stated:

“This is actually one of the most demananding scenes in Doom 3 with many shadow casting point lights. DX12 is now almost twice as fast as OpenGL. Vulkan is still lacking behind but DX12 is the primary API for Windows users which are the vast majority.”

Alongside DX12, RBDOOM-3-BFG 1.5.0 adds support for NVIDIA’s TAA solution. This not only fixes geometric aliasing at the edges but also shader-based aliasing within the geometries like extreme specular highlights caused by the new PBR shaders.

RBDOOM-3-BFG 1.5.0 also brings an enhanced SSAO solution. This new SSAO gives most scenes a lot more depth.

It’s also worth noting that the previous versions of RBDOOM-3-BFG introduced PBR, Baked Global Illumination and TrenchBroom Mapping Support. Thus, I’ve added below a video that showcases these effects.
