Crysis DirectX 9 & 10 MP Performance [Sep 13, 2007, 10:23 pm ET] – Share – Viewing Comments
Total Crysis offers an update on how
multiplayer will work in Crysis (thanks
Voodoo Extreme). A number of topics are covered, including how DirectX 9
servers will be limited compared to DirectX 10 servers, not because of software,
but hardware:
DX9 vs. DX10 – The endless question
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.
Considering several of the techs found in the Dx10 edition but not the Dx9 edition, such as alpha-to-coverage (basically anti-aliasing of foliage, shrubs, etc, one of the reasons it looks so crisp and clear,) we've been told is a Dx10 tech that's not in the Dx9 edition because it's not possible. An example of this is the Dx9/Dx10 comparison video found on gametrailers.com. You can see a very clear difference in the foliage and shrubbery between the two.
Thing is, Valve has introduced this same tech into the Source engine for Episode 2 because Ep2 takes place out in the natural world, not in the city. But whats this? The EP2 engine upgrade isn't a Dx10 only thing? Thats right.. for Valves game it seams, alpha-to-coverage is entirely possible in Dx9!
So yea, it's probably M$ heavily funding Crytek to put certain lovely new techs in the Dx10 version of the game to make it look a bunch better, when in reality, you they could be doing the same exact thing in Dx9.
Oh and the whole 'there is no day/night cycle because Dx9 hardware wouldn't be able to handle it in a multiplayer environment.' Who the f' do they think they are kidding here?
