:-) I'm not a coder, so i can only go on comments made by those who worked on the hardware and from what i've read so far, i get the general impression that likes of:Rebellion, pretty much took Jaguar as far as they could go with Skyhammer....
ATD just wanted to finish contractual obligations and catch up with the market on PS1 development and Battlemorph was really the best you were going to see from them.
I.D? well Carmack+Taylor have expressed their views, Carmack, i'm sure if he went back and re-wrote Jaguar Doom code, could have game running in higher resolution mode than it did and get a faster frame rate from it.But it's a huge leap to assume even a cut down version of Quake was possible.
(Lee) WTR has been quoted as saying he had a better engine in the works for a planned Jaguar racing game, so again there i'd of expected better frame rates etc.
Hoverstrike SE CD which i believe was coded for GPU etc had an extra 3-5 frames per second squeezed out of the hardware.
So my personal viewpoint is whilst i'm sure there were areas of improvement in 3D still to be made, you were'nt going to be able to do what Atari had wanted and that was to compete again'st PS1/Saturn in terms of texture-mapped 3D games.
Hardware simply was'nt designed for that, it was more intended to take on the 3DO/CD32 and DSP based 3D games on SNES/MD
Concerns were raised early on by the limited Ram (but more would of pushed price up and that crippled the 3DO) as would of putting extra chips on cartridge or adding extra hardware to the CD Unit.
I'd of loved to have seen more games converted that the Jaguar hardware really was suited for, things like D.I.D's Inferno, TFX etc or Lucasarts bring X-Wing/Tie-Fighter to it.
Or something along the lines of an updated Hunter or Midwinter or Starglider 2 from the ST era, but trying to fully texture-map games like Supercross, when Atari themselves knew it'd cripple the frame rate, just smacked of Atari's desperation to stay in the limelight.
Sadly as 2D was seen as 'old hat' we never really got to see the Jaguar shine here either :-(.
A take on Turrican would of been superb and filled a massive whole in the Jag's line up, but again i question just who Atari would have found to develop it, what limits on cart size etc they'd of imposed.
I think the Jaguar (and CD32, 3DO etc) simply found themselves victims of a then rapidly changing market.My MD and MCd were by then really showing their age (MD soundchip could'nt handle the samples in SF2 etc, lack of colours made for poor FMV etc) so i was ready to move on, yet many were content to hold out and see just how Saturn+PS1 turned out and before Atari knew it, they were competing in a world where press alone was only concerned with how many texture-mapped polys your system could shift and with what fancy lighting effects etc.
It was in part a very shallow era.
I'm also firmly in the camp that Atari was right to scrap The Panther console as it, like the Konix Multisystem, whilst sounding fantastic on paper, would not of delivered on the hype had it become a reality.
It seemed starved of the Ram it so badly needed, Atari rumoured to be replacing the soundchip with a cheaper version etc.
And developers were NOT chomping at the bit to develop for it.
Mev Dinc (Hammerfist etc) was offered a chance, refused due to Atari's poor track record...
I've spoken to coders/MD's etc from likes of:
Argonaugt, Core Design, Audiogenic, Gremlin Graphics, Bitmap Bros, Domark, Ocean, US Gold etc etc
People never heard of it, no plans...titles they'd released on Lynx had bombed etc etc.Publishers simply very wary of Atari.
What could of been done with Jaguar though, is a debate i welcome.
I so wanted Dactyl Joust, Legions Of The Undead, Freelancer (though that seems to be based on mock up screens), Black Ice/White Noise, but Atari simply seemed content just to get titles out, with little/no concern for consumer and that often makes the system 1 hard to defend.
