Have a look at dlls/wined3d/state.c, state_fillmode().
However, you're likely to run into two problems:
1) The game doesn't necessarily clear the color buffer and just re-render every pixel.
You'll have to change swapchain_present to clear the back buffer, otherwise you'll
just get a colorful mess of old lines and new lines.
2) Render-to-texture: In modern games it is common to render everything to one or more
textures, and then draw the texture onto the back buffer with one or more post-processing
draws. You'll somehow have to figure out the post processing draws and make them
non-wireframe, otherwise you'll end up with a mostly empty screen.
Point 2 also makes point 1 more difficult to solve. You'll have to find the
intermediate render targets, clear them, and also find a proper clear color that produces
a "good" result with the post processing shaders.
Also, Aaryaman's information is also pretty accurate: There may be external programs,
and if you are dealing with an online game expect to be booted from the game pretty
quickly because of attempted cheating...
Re performance: Wireframe mode will only fix games that are limited by fragment
processing. If you're CPU bound (which is the case in Wine most of the time without
CSMT) you'll gain absolutely nothing. Also vertex processing limted setups won't
improve, but those are fairly rare. If you're truly fragment processing limited
lowering the resolution should help...

You'd probably have to hack into the game to
change the rasterizer state to wireframe mode. Many game trainers (basically memory hacks
which are used for cheating) offer D3D hooks which allow you to *switch on* wireframe
mode, but that depends on the DX version too. AFAIK many DX9 onwards games have trainers
like this available. Anyways, wined3d as it is right now can't decide the rasterizer
state of any game by itself. wined3d will merely do what the game tells it to do, so
you'll have to modify the game itself (via methods like the one described above), or
if you have the source-code of the game, then change its default rasterizer state. fwiw, I
don't advocate the former method as it's basically cheating in-game.

Hi all, I know it may sound idiot as I have zero knowledge on 3d
graphics but is it possible to make wined3d to not add textures to
things resulting in a sort of wireframe renderer?
The long and uninteresting background:
I used to play a game called X-moto in 300Mhz Celeron Linux computer,
in its standard rendering mode it was impossible to play the game due
to low fps, but it had an awesome wireframe mode that played smoothly.
So if this could be achieved globally by wined3d we could play new
games on old computers (my overly noob conclusion about all this).
Thanks in advance for any reply,
