yes, both offset mappings (high and ultra) uses the same method for offset BUT ultra mode also reconstruct the z vector (5-6 instructions).

3mood (all maxed) - no offset mapping
-------------------- G70 --------------------
Target: GeForce 7800 GTX (G70) :: Unified Compiler: v77.72
Cycles: 15.00 :: R Regs Used: 3 :: R Regs Max Index (0 based): 2
Pixel throughput (assuming 1 cycle texture lookup) 688.00 MP/s

3mood (all maxed) - normal offset map (high)
-------------------- G70 --------------------
Target: GeForce 7800 GTX (G70) :: Unified Compiler: v77.72
Cycles: 17.00 :: R Regs Used: 4 :: R Regs Max Index (0 based): 3
Pixel throughput (assuming 1 cycle texture lookup) 607.06 MP/s

3mood (all maxed) - normal offset mapping (ultra)
-------------------- G70 --------------------
Target: GeForce 7800 GTX (G70) :: Unified Compiler: v77.72
Cycles: 21.00 :: R Regs Used: 4 :: R Regs Max Index (0 based): 3
Pixel throughput (assuming 1 cycle texture lookup) 491.43 MP/s

3mood (all maxed) - normal offset mapping (super ultra)

3mood (all maxed) - relief mapping (NOTE! borked - texture coords didn't work with relief !!!!!!
-------------------- G70 --------------------
