OsirisBlack's edit isn't clarification. That's just his interpretation, or "just the way he took it"
I dunno why y'all wanna act like people aren't allowed to have concerns about this lol.
Concerns are one thing, but this thread is heading towards FUD territory. All from overheard discussion by devs making no official statements, and the non-official statements themselves can be interpreted more than one way. In other words this isn't even a rumor of 'poor performance' in the way many are taking it. It's an interpretation of said rumor being taken to heart by many.
Here's my take on why
at this point there is no reason for concern:
1) While I'm not a game developer, I am a professional developer and do have a passing knowledge of game development. If this was a situation of devs talking among themselves, I would not interpret 'poor performance' in the layman way. Without the full context I'd actually assume it was meant as 'low performance' versus 'mid / high performance' in PC gamer-speak.
2) From a logical business standpoint, it is obviously not in Sony's best interest to alienate their mass market. It will be long time (if ever) that the PS4K would be the majority Sony console this gen. For that reason alone it doesn't make sense for them to move with a strategy that would subject a majority of their customers to poorly
playing games.
3) We have a long and well proven legacy of games being playable on different performing hardware with the PC side of things. And that is a with differing OS versions, differing processors, differing GPUs, differing RAM, differing drivers, etc. If that is tenable, the idea that it wouldn't be on a console with only 2 differing configurations, all using the same hardware family, and an SDK and drivers that are controlled by a single entity is a crazy leap.
