I stole code for loading .tga from the ATI demo I used ealier. But it still took quite a while to implement, so I really regret that I didn't try PIX earlier.
I didn't know PIX and I guess I shied away because of that. Too bad.
Once I got it up and running, I must say that Im impressed. I can easily see myself getting addicted to it
It does not look like there is anything wrong with the D3DX-loading of the .tga. My ATI-imported code didn't solve the problem either, so I expected that. But what can it be then?
I made a collage of the PIX session I ran. If you are interested in something not shown, let me know. I am also uploading my .PixRun file, if anyone is interested. It is created by the latest DX-SDK (june 2010 - had to download it especially for this, as the DX I run on had an ancient version (DX SDK June 2005).
Here is the PIXRun-file (zipped):
