Tom's Hardware posted a Final Fantasy XV performance analysis with 10 GPUs
A quote from the article:
Developed and published by Square Enix, Final Fantasy XV was first available for the PlayStation 4 and Xbox One consoles back in 2016. It only recently became an option for Windows gamers in March 2018. Was the wait worthwhile?Final Fantasy XV: Performance Analysis With 10 GPUs
For Final Fantasy XV: Windows Edition, the developer used an updated version of its multi-platform Luminous Studio engine. While it remains DirectX 11-compatible, a number of Nvidia-specific features are now part of the package, including Voxel Ambient Occlusion, HairWorks, ShadowWorks, Turf Effects, and Nvidia Flow.
This is incidentally one of the game's paradoxes. While it was conceived for eighth-gen consoles based on AMD graphics architectures, Final Fantasy XV: Windows Edition seems to be optimized for Nvidia GPUs. How does that affect performance comparisons in the real world? Our benchmark data should paint a pretty clear picture.
