[ltp] Radeon PCI works faster, but without TCL ;-)

[André Wyrwa]

Hi,

browsing the DRI pages again, i fiddled a bit with the environment
variables and found that setting R200_NO_TCL results in rates above 500
fps. I even got 600 fps once.

But, of course disabling TCL results in some ugly effects, mostly
objects touching the border of their visual getting deleted (best case)
or loosing parts of them (very very ugly).

I'd very much welcome any explanation what might be the problem with
TCL, and maybe about what i could do to get both, high fps and TCL, if
anyone has some idea about it.

And thanks a lot for all the help and comments so far,
Andre.
