To further my original post, I have now in the past 2 days tried Windows XP SP3, Windows 7 Ultimate x64, and Windows XP X64. BY FAR, Windows XP X64 seems to be the most stable, with the least cpu usage.
CPU Useage in WinXP X32 was around 15-20% CPU Useage in Win7 X64 was above 35-40% CPU Useage in WinXP X64 was no greater than 10% Are there any tweaks or registry tweaks for Windows XP X64 for firewire? I remember reading something about a registry setting to do in XP to stabilize firewire communications or something? Anyways I figured some of you may be interested in these results - so on my near new system, the winner is XP X64 by a mile. 73 VK3LAJ Anthony -----Original Message----- From: Anthony [mailto:anth...@consultexcel.com.au] Sent: Monday, 1 February 2010 4:20 PM To: 'FlexRadio@flex-radio.biz' Subject: Audio tear/scratchy audio Hi All, When i first got my Flex 3000 i was running Windows 7 X64. This seemed to work flawlessly out of the box. I went back to XP after i could not get some programs running that i needed but found that compared to Win7, XP really sucks. So i went BACK to Win7 (without any hardware changes) and i am getting crappy audio out of PowerSDR 1.18.3. It starts off ok but then after a few minutes it gets scratchy and seems to get worse. If i turn VAC on or off the problem goes away and then re-occurs a few minutes later. My system is a dual core 3.2Ghz intel box with 4gb ram.. Anyone have any ideas?
