The Reduced Quality is being Cleverly *Hidden* by Carmack For the Specific reason that it not make Nvidia hardware look bad. This is another case where Money Talks. Believe it.
In other words the overall Possible Quality that the game could show is being intentionally Crippled by soem tricky internal code in order to put the VASTE differences between Rendering Quality paths on an Even playing field. The whole thing is made possible becuase of Proprietary IQ reducing and Shortcut filled Extensions Nvidia coded for their Poorly performing hardware.
Thus it is at the same time A Blessing (For Nvidia users) and a Curse (For everyone else).
in cases like 5600 vs 9600 I see the quality diff being tremendous - but what about 5900 vs 9800? That gap wont be as large, will it? Especially with goodies turned on?
