How to chose DX11 In Games

[pcgamer]

I have the ATI 5770 so i can play games in DX11 or lower and wanted to know in Dirt 2 for example how do i chose which mode it runs in as my crysis game gives me a choice if i right click on it but DIRT 2 does not is there a way to chose which 1 in DIRT 2 ?

I think it's just automatic. Should run in dx11 with default settings. Maybe lowering settings from Ultra would make it run lower?

 

[Airbot]

BTW, Crysis doesn't use DX11. But maybe you weren't asking that..

nah just saying that crysis lets you chose from dx 9 or 10 from right clicking on it

No, unless the game has an option in settings, it will automatically use the DX level it requires.

So in my case will it automatically use DX11 then

DX 11 by default,

Toggling DX11 and DX9 Rendering


Obviously, the big feature in DiRT 2 is DirectX 11 support. But that doesn’t mean we always want to run in DX11 mode. Sometimes, we found it necessary to go back and forth between DX9 and DX11, especially for performance comparisons.

To do that, we edited the "hardware_settings_config.xml" file located in the "[..]\Documents\My Games\Dirt2\hardware_settings\" folder. In that configuration file, there is a field which reads "forcedx9=false". Simply change that option to "forcedx9=true", save the file, and the game will be in DX9 mode until you change it back.

I assume the game will change that to True by default if it doesn't detect a DX 11 capable card.

That depends if the game asks for it. If a game wants dx9 and you have a dx11 card it will use dx9. Or in some cases, like counter strike source, it shows dx9.0+ for your hardware/software. That game calls for dx9 unless set in advanced options.

First off...

6 - Speaking of DirectX 11 – Just because Windows 7 (and now Vista) is DX11 capable doesn’t mean your games automatically run in DX11 mode!!! In order to run in DX11 (or 10 for that matter) 3 things must happen:

1- The Windows must support the modes – Window 7 and Vista (DX10 & 11)
2- The game must support the Mode(s) - Games with DX11 Support, Games with DX10 Support
3- The video card must support the Mode(s) – ATI 5000 series cards, Nvidia GTX 470, 480 (more?)

If any one of those 3 requirements isn’t met the game defaults to the lowest DX mode possible - DX9 (or lower depending on the game).

Here's an example - You have Fallout 3 (DX10), Windows 7 (DX10 & 11) an ATI X1950 PRO or Nvidia GT 8400 (DX9 cards) - well….Fallout 3 will run in DX9 because the video cards are only capable of running in DX9 mode.

On the other hand, using Fallout 3 (DX10), If we have an ATI 5970 (DX11) and Window 7 (DX10 & 11), the game will run in DX10 mode because the game does not support DX11.

Now, if we have a game like Metro 2033 (DX11), Windows 7 (DX11), and an ATI 5970 (DX11), well…we have all the requirements met and the system will run in full DX11 mode!!!

On the other hand – say you are running a DX10 or 11 game and wish to run in DX 9 – some games like Crysis, Crysis Warhead, or Bioshock will let you by simply right-clicking the game’s .exe and choosing the mode you want to run in. See this post - Force DirectX 9?

So… To sum it up, unless ALL components are DX10 or 11, you are running in DX9 (or lower depending on the game) by default!!!


But my question is this... Can you not toggle from DX11 to 9 in Dirt2 like these games do as shown in this post??? - Force DirectX 9?

Yeah, I read the article, just saying.

Because the game gives the option. Directx is backwards compatible software.

To be specific about my question - Can you not toggle from DX11 to 9 in Dirt2 like these games do as shown in this post??? - Force DirectX 9?

I'm asking why Dirt2 can't be forced in a lower DX mode like the games I spoke about here - Force DirectX 9? In short why does it need to be done by hack.

 

[stormy13]

Some games do and some don't. BFBC2 is another that doesn't but you can make the change in the settings.ini located in "C:\Users\Your Name\Documents\BFBC2" Just locate the following line,

DxVersion=auto

and change it from auto to DX9, DX10 or DX11 depending on which you want to force. Auto will only run at the level the video card supports.

In regards to Dirt 2 unlike BFBC2 which comes with support for all three versions, Dirt 2 only supports DX 9 and DX 11. May be one reason the devs left the option out of the in game settings.

 

[sygnus21]

Yeah, I gather that DX11 will become default as more and more games and hardware is released. Looking at it from that perspective, I guess I can see why the initial games had a simpler option as there weren't too many DX10 capable systems, and it was also an easier way to show off the differences between the two Modes.

Maybe

Because it requires it. That be like trying to play Shattered Horizon in dx9. It NEEDS dx11 or it does not work.

You obviously aren't getting my question, nor reading my posts.

At any rate stormy did and thus answered the question.

Thanks


Now I'm not sure what you mean here...

...But a DX11 game can be played in a lower (DX9 or 10) mode. It might not be as pretty as DX11 but it will play.

As you've pointed out, DirectX is backwards compatible

 

[stormy13]

DX 10 actually,

Shattered Horizon

Considering when that game came out it couldn't possibly have been DX 11 only if no other reason than Nvidia didn't have any DX 11 cards out.

 

[sygnus21]

PS I just read this, so don't shoot me...

Please, make Shattered Horizon work on XP!

Sorry, it just isn't feasible. The game engine is fully designed around DirectX 10 and it would require a complete engine re-write to make the game to use DirectX 9. Additionally, no DirectX 9 level video card would have the needed performance to run the visuals acceptably even at low settings, so chances are that if you are using a PC that was purchased back when Vista wasn't available, it doesn't have the hardware to run the game anyway. OS upgrade (or a computer upgrade) is the only option. Sorry.

I guess they made this game to specifically only run in at least DX10 mode. That's interesting.

Game looks interesting BTW.

 

[Heroxoot]

You have proven my point. I got it wrong, it needs bleh vista, but it still needs dx10 to run. It gets what DX it wants or nothing. Some games can run in different dx modes, others cannot. Some games like valve games get advanced options where you can use a command such as -dxlevel 80 which sets dx8. Point is, it uses what it wants. You have asked if there was a way to run dirt2 in dx11? If it wants DX9 thats what its going to use. Blame the programmers for not taking advantage. I cannot understand what you are getting at. If it can switch then it has an option. Find it and use it.

Edit: dirt2 should do it automatically.

I don't have a problem admitting when I'm wrong, I have a problem being told I said something that I did not say!!!
