According to a report from Golem.de (German language), with the upcoming Wolfenstein 2: The New Colossus game AMD Vega owners will have the advantage of FP16 shader support from a new version of the id Tech 6 engine. The game supports both DX12 and the Vulkan API, but the use of half-precision calculations – the scope of which has not been specified – will potentially offer higher frame-rates for AMD Vega users.
AMD provided some technical details about Wolfenstein 2 during their Threadripper/Vega tech day, and this new game includes “special optimizations” in the id Tech 6 game engine for AMD Vega hardware:
“For what exactly id Software (is using) FP16 instead of FP32, AMD did not say. These could post-processing effects, such as bloom. The performance should increase in the double-digit percentage range, (though) id Software did not want to comment on it.” (Translated from German.)
