Finally decided to dive back into flight simming after about a year away. Currently running FS2004 on the following system:Dell 8250 PIV 3.06 with hyperthreadingATI Radeon 9700 Pro with Catalyst 4.3sAudigy 2 Sound with latest driversWindows XP ProDirectX 9.0bMS Force Feedback 2I've spent a good part of this weekend searching Avsim for FS2004 tweaks and have managed to improve system performance (FPS) quite repectibly but am still plagued with the dreaded sound stutter whenever ATC starts to say anything. Very distracting :(One of the tweaks I read is to turn down sound card acceleration from full to basic... but this did not correct the problem. Besides when you're running the latest sound card with the latest driver it sure does seem strange to reduce acceleration to try and improve sound performance.Is there anything else out there that some of you have stumbled upon that corrects this disturbing performance problem?TIA for any suggestions/advice!Doug

I had the same problem, go to the AVC control panel, if you are using DirectSound for the output device change it to wave, or vice versa

Hi Doug,Turn down the acceleration in DirectX not the sound card. If you have used DirectX to do this, then pardon me for misunderstanding. If you have not turned down DirectX, then from the Start Menu, click on Run, and keyin dxdiag. Go to the Sound page and you'll see the acceleration slider near the bottom of the page. R

>I had the same problem, go to the AVC control panel, if you>are using DirectSound for the output device change it to wave,>or vice versaThanks all for the responses.Sorry I wasn't clear when I presented the problem. The ATC I'm refering to is the default ATC in FS2004. I don't do any of the online ATC at this stage. I already reduced the DirectX sound acceleration in increments and was not able to correct the stutter at any of the reduced positions. At this stage I'm not sure what the solution is. If having one of the very the best sound cards available (IMHO) along with the latest drivers won't do the trick, maybe there isn't a solution and I need to learn to live with it.Anyone else out there with a good idea?TIA... Doug

Hey Doug,There's also a slider in the Sound page of FS9's Options menu. I don't remember how it is labled or what it does but have you slid that one? If not, try it. I had this problem in FS2002 and FS9 and the DirectX slider fixed them both. R-
