That's not going to make any difference to my point though. Tekken 7, and Soul Caliber 6 (and actually most BandaiNamco) games on PC perform great with no shader comp stutter, that goes for fighting games in general. Which, if you understand the issue with UE4 PSO gathering for developers, makes sense because of how small scale fighting games are in comparison to most other games. Essentially with fighting games you have set arenas and characters, so it's easier to play with every character in every arena, and generate all your PSO data for compilation during loading.
Basically BandaiNamco have proven to me that they know how to properly do it.
