Messed-up mesh rendering on every SteamPipe Source game, when running on DX9

This problem has been haunting me for quite some years... yea...

It started waaaay back in the TF2 Halloween 2010 update. It ran perfectly fine before, but what happened since then is, when I tried to run on DX9, everything was messed up. Crazy colors, messed-up model rendering, crazy textures...

The solution was to downgrade to DX81 based-rendering, which was quite a downgrade in graphical quality.

The console was spammed with errors that referenced "messed-up mesh rendering", and told me to build shaderapixdx9 in debug mode, which is something I cant quite do.

"ERROR: failed to create vertex decl for vertex format 51483! You'll probably see messed-up mesh rendering - to diagnose, build shaderapidx9.dll in debug!"

And now, this rendering problem is haunting me again, happening in every SteamPipe Source game.

Heres a Half-Life 2 screenshot:

Whats really sad is that it ran perfectly fine before on DX9, much like TF2 used to run pretty well before the Halloween 2010 update.

Here is a TF2 video for further reference:

Thats it... I kinda dont want to be stuck in DX81 mode forever, especially when it ran perfectly fine before...
