Well, nothing really specific. Just figured if I could turn it on with no
loss of performance, where would the harm be? (I know it uses slightly more
memory, but whatever)
Although as of late I am playing Half-life 2 and Painkiller...... both of
which are Direct3D, and both suffer very little from tearing, however.....
if it could be done, I'd do it.
