<p>Hello</p>

<p>Could an on-board sound card impact on fps instead of a PCI sound card?</p>

<p>I have my fs sound definitions set to% R P 0det52 flying over detailed areas, with a lot of communications going on (default fs ATC), my fps drops.</p>

<p>All system drivers are up to date, I’ve my hard drive de-fragmented and optimized, run ACA2005, corrected all DXT3 textures that didn't have alpha channels with dxtfix, etc.</p>

<p>My current hardware specs:</p>

<p>Asrock 4 core dual sata2, with 2 Gb DDR2 RAM,  INTEL CORE2 QUAD CORE Q6600, ATI 5700 HD</p>

<p>My current fs9 software:</p>

<p>REX (texture only), ASE (weather engine), Mytraffic 2006, Shoot (speech recognition program), FDC, enb series</p>

<p>It worth’s buying a Asus Xonar DG 5.1 PCI (cheapest)?</p>

<p>Thanks</p>

<p> </p>

Not sure what the clock speed is on the CPU you listed. That could be an issue here, no matter how many cores it has since FS9 will only use one core in any case. I had a quad core AMD CPU which ran at around 2.4 Ghz, but I've gotten much better FS9 performance from my newer Intel dual core CPU which has a clock speed of 3.0 Ghz.

 

Also, 2 Gb of RAM isn't a whole lot on a Windows system these days, let alone one that's running FS9 (or FSX, for that matter). You might consider doubling that to 4 Gb of RAM. That could also help.

 

I also noted that you didn't mention your OS. FS9 should run optimally on WinXP or newer OS. You also mention running a speech recognition program ("Shoot"). Is that running when you run FS9? If so, why? It seems to me that that kind of software could use up a lot of CPU clock cycles, and FS9 (or any of its addons I've ever heard of) can't use vocal input anyway. You might try turning that off before running FS9. A good rule of thumb is never to have any other software running when you run FS9 unless you really need it or it contributes to your FS9 experience, as FS9 can be a real CPU hog and any other software which is using CPU cycles while its running can slow you down.

 

Based on the data provided, I would think that your onboard sound chip is probably the least of your issues. I haven't used a dedicated sound card in years, and I suspect that few people running FS9 probably do so. There's just no real benefit to be gained from it unless you are a musician or composer and need the extra features a dedicated sound card can provide for those reasons.

 

Hope some of that helps. Good luck.

Fully agree, I've used both onboard and dedicated on different machines over the years. For several generations now, playing simple looped wav files concurrently and/or in sequence is not heavy lifting for onboard sound technology.

It really seams like the CPU can’t handle all the instructions.

I’ll have to lower fs9 settings in order to have good fps.

Thanks for your replies!
