Benchmark Results: DirectX 11 Versus DirectX 9 And 4x AA

by

With DirectX 11 taking a colossal performance toll, what happens when we combine it with 4x AA?

It looks like these new DirectX 11 cards are quite efficient when it comes to AA, as the results don't change all that much. Only the Radeon HD 5750 and 5770 really suffer, but 1920x1200 performance remains playable, if not ideal. The Radeon HD 5850 and 5870 cards continue to provide playable performance at 2560x1600, which is quite an accomplishment. Only the Radeon HD 5850 cards in CrossFire are able to provide the smoothest minimum and maximum FPS results, however.

TBH it plays better in DX9 than in DX11. Full settings in DX9 look fantastic at a high resolution whilst DX11 stutters at times.

Soon be a patch out we hope

have tried the game in both modes - simulation with the hardest settings and the arcade style... using Logitech wheel and the keyboard and the xbox controller - the game is just crap... it's not a simulator and it's not an arcade... just something in between for people wanting to look at cars rather than drive them... NFS Shift is much more realistic than this... Grid is much more enjoyable than this. I do realize it's rally racing versus normal racing games I have mentioned... but if you really want a proper rally game and don't care about the graphics - Colin McRae Rally 2 is the way to go...

The blur IS in fact caused by the postprocessing. The same goes for GRID - if you alter the engine with:
postprocessing "false" instead of "true" the game becomes beautiful and clear. With postprocessing enabled, GRID looks like someone smeared lard all over your monitor.
Now give me GRID 2 Codemasters :)

Its a Codemasters game and therefore utter crap for some reason. Never been able to place why they are so bad; but every thing from them is so boil in the bad processed factory trip. They have no finesse. I think there must be one manager high up that likes to put his stamp on things and is just an awful guy the poisons other peoples hard work.

I must assume that most of the people here have either not played Dirt 2 or simply hate off road titles so much they blindly won't even try getting into this beautiful and addictive game.

I'm personally not much of a fan of off road games and find the control of the cars in most of these games to much like sliding on ice than driving on gravel/mud/tarmac but I feel the handling in Dirt 2 is phenomenal for an off road title, well done Codemasters and the programmers and not forgetting the developers of such an awesome engine, Hurry up and bring out Grid 2!!!! :-)

I've played this in DX9 and DX11 modes and I love the water effects as well as the way the flags/banners flap around in the wind. I would not advise anyone to get a DX11 card just for this game though because it looks superb in DX9 too, just not quite as many bells and whistles.

Enjoy this game, I do! :-)

I have to agree with jkay69,this is a very addictive game and very nice to look at,iam more of a sim than arcade gamer,i love GTR Evolution,just waiting for Codemasters F1 title.Playing Dirt 2 with a G25 wheel brings the game to life,you feel more involved than playing with a pad or keyboard. There is a downside,but i think its more to do with drivers than the game,iam running two 4870`s in cross fire,now they are directx 10.1 cards,so i get to play the game in directx 9,i have also played it on a rig with a 5870 card,directx 11 and it runs really bad,it stutters and does not run smooth at all,so at the moment not alot to be said about directx 11 drivers.

Anyone looking a driving simulator... forget about your Gran Tourismos and GTRs... both are lawnmower simulators.

Get rFactor. Get a force feedback wheel. Get racing. :-)

Got rFactor,i did not think much of it tbh,its all about modding andyou have to put the mods in all the right folders,screw that for a game,ive played a little bit of f1 on there and i have to say the graphics where very good,but that game just does not float my boat sry.

Does this mean that the ATI HD 5850 is the best? I don't understand the comparison...

Can you force it to use the DX code path if you have a DX11 card? (In my case a 5850?)

I am sure that if your card supports DX11 then the game will automatically run in it,my bro has a 5870 and when i played his he could adjust settings that i could not and iam running 2x 4870 which are DX10.1,so that means mine automatically runs in DX9.
