It used to be - about 7-10 yrs ago - that you could say that if your computer cannot run the game, you are probably not a target market.
These days, when even cheapest of laptops ship with SM 2.0 cards, the only PCs you can find that can't run SM 2.0 are the ones that are kept as second/third computer at home - which means that in that household is still at least 1 computer able to run it.
I do, however, understand, your unwillingness to learn the shaders. They are not really that straightforward and debugging them is, by default, PITA - especially compared to FFP.
Long-term, you can't avoid shaders, really.
