The more I think about it, the more I'm inclined to suspect that it is indeed a fact that 4K + full scene 8xSSAA is impossible on any currently available consumer GPU solution at playable framerates.
"Impossible" is a moving target.
Let me put it another way: what were you doing back in 2007 when the game first shipped? There's absolutely no way you had everything on "very high" without getting a single-digit framerate, unless you were running 320x240 on four 8800Us.
The problem is that you're trying to use this completely open-ended criteria. There's practically no limit to the resolution one can use, or the amount of AA one can pile on to a game.
Open-ended?
The resolution drop-down tops out at my monitor's max resolution.
The AA drop-down tops out at 16xQ.
Overall background AA options top out with the GPU/driver combination.
None of those are "open-ended".
The equivalent would be if I expanded my criteria to include all potential .ini modifications etc. You can't tell me, with a straight face, that playing a game with 4K + 8xSSAA is as realistic a proposition as playing a game with all it's in-game detail* settings configured to their maximum values
Realistic isn't up for debate - I think your settings are unrealistic but that's opinion, and not my point here.
What I'm saying is that some drop-downs you choose to not max out (e.g. AA), but others you do. So you too are reducing settings to get extra performance.
I think I had settled on 4xSGSSAA. I spend hours testing various AA schemes before I gave up on my first Haswell system (courtesy of Asus' z87 RTC bug), and now I'll have to do it all over again because I neglected to document the outcome.
4xSSSA? At what resolution? A single GTX780TI will slideshow at that setting at my in-game settings, much less your very_high_maxed_out settings.
*When I say 'details', I mean standard finite menu options like draw distances, physics, etc, excluding the potentially infinite realm of resolution and filtering. Sorry if this wasn't clear. I wouldn't call something like AA 'detail', as it doesn't add any new detail, but enhances existing detail (not to downplay it's importance). I guess one could argue semantics (eg. higher resolution can resolve finer, and arguably 'more', detail purely by virtue of having more lines) , but I've now outlined my use of the terminology.
Finite menu options? Like resolution and AA you mean? Or do those menu options grow infinitely long on your system when you click them in Crysis?
But I don't agree on the objects being negligible, and I don't know why you choose to compare that setting to SSAA, which is entirely GPU dependant. My last post was clearly relating to CPU dependant settings. You don't 'give up' CPU intensive detail for GPU intensive filtering.
There's a combined pool of performance made up of collective CPU and GPU performance. With the way you run your games, it's no wonder you have constant performance problems.
If Crytek had capped all settings to LOW we wouldn't even be having this conversation. That's why I think consoles and/or engines like Call of Duty suit you much better. The developers make the choice for you and don't allow unrealistic settings, so you can bask in the glow of seeing all sliders "maxed".
