I have the Steam version of Deus Ex and even though I followed the instructions in the readme to the letter it's not working. Is this something to do with the Steam version or did I miss something?

Are you sure you got all the "path" lines BEFORE the regular ones? The game is going to find the first texture matching the one it looks for and just go for that. You want it to find the NV Textures first.

Yep I put Paths=..\NVTextures\*.utx before Paths=..\Textures\*.utx.

What renderer are you using and what are the settings for it (found in deusex.ini?

I hate to ask, but did you change the exe? The Steam exe changes a vital file or two apparently.

I'm using Directx10 and I replaces the default exe with Deus Exe. Where are these settings you are talking about?

If you could go to DeusEx.ini and copy down the code in the D3D10Drv.D3D10RenderDevice section.

Also, when launching Deus Ex did you go to options and change the render to d3d10 before pressing play?

[D3D10Drv.D3D10RenderDevice]
DetailTextures=True

And yes I did.

Have you got this runtime installed? http://www.microsoft.com/download/en/details.aspx?displaylang=en&id=5555

Also in the "Configure" part of the Kentie launcher have you set the game to run in 32 bits?

When I try installing that it says I have a newer version on my computer. Also yes it's in 32 bit mode.

That DetailTextures setting has nothing too do with New Vision. The renderer should just use the new textures automatically. It was the older renderers, specifically the OpenGL one that required a setting changed if I remember correctly.

Now, when you say, not working; do you mean it crashes upon launch or you can open the game and play it fine but the HD Textures don't show up?

I had the same problem, but after looking around I discovered that the deus ex exe was using a different .ini file that was not in the Deus Ex system folder. It was using one found in <Drive Letter>:\Users\<Username>\Documents\Deus Ex\System. Once I altered the deusex.ini in there as described it worked

Shit. That's the second time the replacement .exe has caught me out.

TheGoonerKid is right. In the Documents Folder, Go to DeusEx\System\DeusEx.ini and do the changes in there instead.

That's all in the readme though... so... you guys *do* read those... RIGHT?

Nope because New Vision hasn't finished downloading yet.
And the fix was quite simple if you know how Deus Ex works.
