On fixed pipeline the thing is ugly. On shaders it is horribly slow.
Then it is buggy, the physics are horribly broken, and some default stuff are way beyond broken.
Back then, torque was kinda expensive, they used source access as selling point, but there was a internal joke in the community that the source was available because without it was impossible to do anything. You just plainly needed the source to do even things seen in official samples.
Also when I used it the documentation was so bad that you did better by not reading it and going by trial and error.
