I must add, I have not had much technical knowledge in regards to programming etc, so can't really understand the problem, but those games from them that I have played on my console, have all been very impressive....I think you're misunderstanding what optimsiation is. Optimisation is making the best use of your resources, and not necessarily doing most new-and-exciting things. A well optimised PS1 game can't do any of the modern technqiues, but it's still well optimsied because it's making great use of what the hardware is capable of. Crysis wasn't well optimised because the harwdare was underutilised relative to what it was possible of achieving. By all means make the claim that CryTek were focussing more on techniques and pushing game tech forwards than they were concerned with getting the best use of the hardware, but don't confuse the two. the fact that CryTek have been able to revisit their code and tune it much better to run on less capable hardware proves that it was not well optimised. If it had have been well optimised, the hardware running the game would have been maxxed out and lesser hardware wouldn't have been able to achieve the same results!
As for the argument with bigtabs, online interactions always seem more fraught when dealing with conflict. So don't worry about them. Looking at it for what it is saves a lot of angst.
I think he has a point. Optimized or not, I looked at Crysis through envious eyes for a reason.
