direct3D acceleration is not available in Windows 7

same problem i have it ......but as updated relates to regedit......it was not succesful ....plz help what to do

"At first I had windows XP 32 bit on my computer, and after installing Tomb Raider (2013) I was able to run it... I'm using ATI Radeon HD 5450."

Interesting. I suppose that as XP only has DX9 the game couldn't force DX11.

Also unusual for a game to default for what are effectively high or ultra settings as most

games will go for settings below the capabilities of the card they detect.

• If you used the configuration files (or saves in some cases) that were in your User folder on XP 

(if there were any),  after upgrading to Win7 64bit they would have also been a potential source

of the problem.

Anyway - Maybe because system set-ups vary so much, it's not uncommon for games fixes that

are not necessary for some to work for others.

Another example is putting a Direct X file in a games install folder.

Maybe I missed it before you used the link tool, but I didn't see the part below -

About this text from Wiki page: Manually set the aspect ratio to that of your monitors.

Before I found this Wiki page I tried to set every possible resolution manually, but the problem was still there.

I know that my post is not the exact answer to the question, but I thought that maybe it will help.

About the question on beeing able to access the games graphics settings before this error:

This Tomb Raider opens like this: I click on a shortcut to the game and a window opens. This window has 4 (or 5) options: Play, Options, ... So I acces the options before I enter the game.

At first I couldn't acces the game graphics settings (everytime I clicked on options, the menu crashed).  After googling a bit I found one poste, where someone was giving a link to a page where I could copy and save the text in a text editor and save it as *.reg. After I launched this reg file, I could open the options window, but I was still recieving the "failed to initialize Direct3D with curent settings" message when I clicked the play button.

So after I did what I describe in my first post here, I was able to run the game for the first time on win 7.

At first I had windows XP 32 bit on my computer, and after installing Tomb Raider (2013) I was able to run it (and never got "failed to initialize Direct3D with curent settings" message). But I thoutgh that since a 64 bit OS would use more RAM I formated my HDD and installed win 7. And then this problem appearred (updating my graphics card drivers didn't do anything).

I'm using ATI Radeon HD 5450.

I've fixed the link now (I guess this is what you ment with it being incomplete).

I don't have the game but would not have thought it would enable DX11 setting automatically

(especially if the game detects a DX9 or DX10 card).

Normally you would have an option to select some settings that use DX10 or 11, which would not be available when using a card that is not compatible, or to use a DX10 or 11  .exe .

But Tomb Raider (2013) does seem to have a lot of issues, so I guess it should not come

as a surprise that it would.

• It also looks like DX11 effects are causing problems with Nvidia cards though (which seem to have

a lot of  general issues since driver versions 310.90 & 314.22  with series 400 & 500 cards).

"failed to initialize Direct3D with curent settings."

Also from Wiki page-

"Fix for "Failed to Initialize Direct3D with current settings":

Manually set the *aspect ratio* to that of your monitors (ex: 1920x1080=16:9, 1920x1200=16:10) - "

Interesting bug that....  The fix you posted is for forcing both 'custom resolution' and  DX9.

-Not the same message, or issue, as the OP though.

Were you able to access the games graphics settings before this error, or was this the first time

you launched the game ?

What graphics card are you using ?

btw - your link is not be broken, just incomplete.
