I'm hearing that when the 9800GT series cards use DX10 they lose performance even if the game settings are the same with DX9 and DX10. I went from 31.8 fps to 36.79(You might as well say 36.8fps) When using high settings in Crysis with DX9 and DX10 with 2xAA. so I went from lower 30fps to upper 30fps. All in all it was like a 15 or more % increase. I hear that the 8800 series cards LOSE performance with DX10. Why is that. Maybe it has to do with the Radeon 4800 cards being made more up to date with DX10 requirements(I'm talking about DX10.1)?
