Sorry, I said I was done. But I couldn't let it go on the drive home. My fault. I apologize.
Thank you. That's a far better analogy that the silly car. So let's run with your example.
Can you tell me which games don't run as well as they used to? I've not seen that personally, but to be fair, I'm not playing super intensive games. My tastes are more along the lines of The Room, Forever Lost, solitaire, etc. They don't exactly tax the system if you catch my drift. I've not heard of games running slower. Can you give some examples? I'm not talking about slower to open. I'm not talking about the game not opening at a smooth 60fps. I'm looking for games that once loaded, don't run as well as they did prior to iOS 9. I've yet to see any reports of that happening.
By the way, I'm also not talking about games with bugs. I have one that won't run period since updating. I have another that runs WAY too fast (you can't read the dialog as it runs past multiple screens of text in like .1 second). Hell, I have a minesweeper clone that's hasn't run right since iOS 4 or 5. Those are clearly bugs in those apps where they need to be updated for iOS 9. I'm looking for examples of games where the OS is the culprit, not an actual bug in the game. Or to put it in terms of your video drivers again, I'm not looking for a single game that's having issues. If it's the new drivers causing issues, you'd expect to see symptoms in most/all of your games. If only one game had issues while all others benefitted, I wouldn't necessarily immediately blame the new drivers.
I've heard of TONS of cases of animations being slow, frames being dropped, things taking longer, TouchID slowing down, etc. But this is the first I'm hearing of slowdowns within the apps themselves.
You may or may not have examples. Honestly, I don't know. If you do, I'd love some to look into it more. If not, I come back to the fact that it's really just the bells & whistles that are having issues. There are no far-reaching, serious bugs that are affecting multiple apps that I've heard about. I accept that some people find these UI issues annoying. Personally, I don't. Neither point of view is more valid than the other. As long as my app loads and runs correctly, I don't really care if it took a second or two longer to open. I don't care if the opening animation was a smooth 60fps. Sure it's nice. But for me, I can look past it because it's the app I'm interested in. Beyond some odd UI issues, I've been happy with iOS 9. I find it more stable. I really like some of the new APIs. I haven't noticed any performance degradation in the apps I use. With most of the apps I use, I probably wouldn't notice a performance boost (I have a 6 Plus). If you don't find it acceptable, I'm ok with that. I do feel some folks are taking things too seriously and placing too much emphasis on what is fairly insignificant in the big picture. My opinion of course. I wouldn't think of switching phones over it and can't fathom the thought process behind that. I support those who would like to get things fixed. But I can't support those people who want to turn this into a major disaster. At worst, Apple looks a little foolish. I've been a programmer for over 25 years. I've learned as far back as college that the bells & whistles can turn something good into something great. The finishing details are important. But they delivered a fairly solid OS in my opinion. It would have been nice with those finishing touches. I don't know what happened. But it does seem to be a pattern with every major OS release. And next year I'll buy the 7. And probably the first month or two will be slightly rocky in areas. And then things will improve. And there will be more threads like this. There is every year.
