No he didn't. And the 1.39 is quite old.
April 2014. Not that old.
But you already decided who is at fault, despite no evidence. Rather only evidence showing its not GameWorls.
No, I read the thread and made conclusions on that basis. Erenhardt made a pretty good case, and the fact that the dev was working with Nvidia well prior to Oct 2nd 2015 certainly indicates that the 1.39 could have been an incremental step towards full implementation of GameWorks.
How long do you think it took them to integrate GameWorks into their existing product, anyway? It's not like they pushed the magic GameWorks button a few months ago and magically created new client software. It probably took them months, if not well over a year to get everything working right, and I expect that many of the "improvements" were patched in incrementally.
I mean, really, what else would have caused such a bias against AMD video cards? Have you ever seen anything like that where GameWorks wasn't involved? Do developers just have some uncanny knack for destroying performance on AMD's VLIW and/or GCN cards without doing anything much to Nvidia's?
The entire thread backfired on the OP and supporters due to poor research. Changing random events together
Sorry, it's not like he's been banned for spreading false information. The forumfolk haven't gotten out torches and chased him into his castle. Seems like he's doing okay, actually. There was some arguably off-topic banter about Frostbite but that was hardly a disaster.
At the end of the day, SOMETHING strange happened with that client software. GameWorks is a definite possibility. Again, if it isn't GameWorks, then what? You're the one cooking up some alternate theory explaining the changes in performance. Why don't YOU ask the developer?
