Hi Guys, I had to go back to Catalyst 3.7 from 3.9. Catalyst 3.9 was dogging down the graphics as well as sound. I'm getting much better and more fluid frame rates as well as more reliable sound. No Texture glitches and no sound cutouts anymore, no popping speech, gone. I'm getting frame rates between 35 to 50 in the cockpit. Much slower with the mirror's on though, but Oh Well............BTW, I have hardware acceleration turned all the way, 44k sampling rate.
