Re: Performance of the new RSPdx

Dale Elshoff WB8CJW <dale.elshoff@...>

Hi Mike, can you provide any suggestions of how to reduce/eliminate freeze problems and improve pc performance?  I don't think stepping back to Windows 8 would be easy or necessarily productive but I'm willing to try about anything that has worked for others.  Maybe you know of a utility that would optimize the system.  I've used IO-Bit products, CCleaner, MalwareBytes from time to time.  Avast anti-virus probably knocks the performance way down but have to put up with that or something these days.

SDR Console rev. I'm using is v3.0.19.  Any idea what it means when the volume slider track is red?  Seems to occur in any FM mode regardless of the level set in the App volume and device preferences.  Still red with SDRC stopped.

I use Thunderbird for email and Firefox for the browser but it is usually not running.  If I play a solitaire game with SDR Console running the audio gets badly chopped up.

I have set SDRC to a higher priority.  Maybe that will help.  Also increased to max the program audio buffers with no noticeable difference.

There are 291 services - not all are running or enabled.  I wish there was a "removal tool" to clean some of that junk up.

Maybe the sdrplay_apiService.exe causes problems.  I have no way to gauge that.

Maybe its time for a Win10 reset. 😮 Yikes!  I hate to even think of it.  It was a royal pain getting the Microsoft validation to go through after Win7 then to get the sound working.  Most performance gained will be drained relatively fast according to various web references.

Any comments are welcome.


P.S. After bumping up the SDR Console and the SDRPlay API priority I have had no program crash or audio dropouts even running my Spider Solitaire and doing multiple shuffles that really hacked things up.

I used SDR Console at first but now I find SDRUno is more stable on my old I5, 8GB, 2.4GHz. laptop.  My pc is under powered for SDRC running the RSPdx even though cpu usage is lower it would often crash or lock-up often requiring a complete reboot to recover then it would run for a while and randomly lock-up, especially listening to FM broadcast or if some change were made to a menu item - gain, etc.  I would prefer to use SDRC but I need to upgrade my computer at some point before I can.


Dale, I'm not sure I agree with your opening line.  The latest SDR Console 3.0.20 test kit (along with 3.0.19 previously for that matter) runs without crashing or lockups on my "old" 2013 HP Pavilion g6. This PC cannot be upgraded to Win10 so it's running 8.1.  It is an 1.5GHz AMD A6-3420M with Radeon HD graphics and 8Gig memory.  Along with SDR Console, I'm generally running VSPE, a VAC, CSVUserlistBrowser and Audacity at the same time. 

Not trying to start an argument, but you may have an opportunity to resolve your crashes and lock-ups before the expense of upgrading.
