DX9 vs. DX10 – Multiplayer differences
Source: TotalCrysis.com 09/13/2007
"To shed some light into one of the most discussed topics regarding Crysis multiplayer I would like to explain you the differences between Crysis MP DX9 and DX10.
As for the DX9 version we won’t have physics and day and night cycle in-game. That means you won’t be able to shoot down trees and/or alter any other objects than vehicles on the map. Additionally the time of day setting doesn’t change dynamically. This is caused due to the tremendous server load such physics might cause on crowded gaming servers. Still you will be able to experience maps with different time of day settings since the maps can be altered in the Sandbox2 Editor.
Rather than providing the community partially working features we limit this for the DX10 version only. Due to the strong hardware available with DX10, server load is less and performance is increased. This ensures the pure physics and day and night cycle experience without any limitation.
Gamers with a DX10 card are able to play on DX9 servers, but with the limitation of the respective server. Vice versa it is not possible for gamers with DX9 cards to play on DX10 servers due to the limited features."
It seems like there will be pretty major differences between DX9 and DX10 in terms of eye candy.
