I had upgraded to breath a little more life in the 6 year old Mac so my boys were not hampered by using the slower machine in their duels with Dad, who gets first dibs on the fast machine upstairs (its unfortunate that they could often beat me with that ancient machine - but we needn't talk about that).
So when I had installed the new cards and found that playing TT was jittery beyond belief, while other games seemed much faster (as one would expect with a faster processor and video card) i cried out to my TT friends.
Great responses from NUTS, Roo, BC and Rx and also Azazel (yes he watches over all of us) who pointed me to the Utility below that I could specifically fine tune for TT to get best performance from it.
It works much better now and much better than before the upgrades, so it was not money thrown away.
Now when the new imacs come out we will get the whole Swift posse playing at once.
Again many thanks for the suggestions and help!
