Jason,

Vert sync on = Stutters

Vert sync off = No stutters

Sli tick box makes no difference.

Why then even with a camouflaging your thinly veiled pejorative (you may have to look that one up ) I still don't see it helping your argument.

Let's not make this personal, or take it to PM if your feelings were hurt.

Roger that, Ricardo

HD4870X2 and the strobe effect is back for me even with the drivers that I used to get it to go away with the last upgrade.

It seems with every upgrade this strobing comes back and I need to remove and reinstall drivers until I get one that gets rid of this strobe effect. Which in effect causes me to lose interest in the sim and when I finally load it again I find I need to update and go thru this strobe bug removal process. Not blaming RoF or ATI but seriously someone has dropped the ball once too often for me, not compulsed to buy a new kite to fly in this strobed arena.

What to do ...

I find I get bad stutters while zoomed in on trees, and flying near buildings on the winter terrain more so than the other terrains...
