I know I need a better laptop but for now ……..

I have an older Acer Aspire One with 1.5 Gb RAM, running two displays.
I am trying to run SDRuno V1.22 or V1.23 on a SDRPlay RSP2, N3FJP'c AC Log, Omnirig, VSPE and a Winkeyer (I gave up trying to add CW Skimmer in also) for the upcoming Field day.
I am hoping to show off what a SDRPlay receiver can do to the new club I joined.

(Believe it or not, I managed to get everything (except CW Skimmer) linked up and talking together).
The transceiver is an ICOM-735. It may be old but it has a full RF receive output on the back so it is realy easy to connect my RSP2 to it.

My hope is to find a combinations of settings that will run good enough for Field Day.
As it stands (default settings) SDRuno load hovers about 36-39% and system loads hovers around 89-94%.
As you can guess, the setup stutters a lot.

If I mute SDRuno, enable the transceivers audio and just use SDRuno to spot signals it kind of works for me.
It would be 200% better if I could use the SDRuno audio output (If it didn't stutter).

Any suggestions for SDRuno settings to help to lower the system load?
I tried HDSDR but for the little bit of system load gain (It still studders) I seemed to be giving up too much functions that SDRuno offers.

Hi John,

You obtain the smallest load on the PC system by keeping the value in the SR window to 2 (minimum bandwith) and the highest value possible in the Decimation window.

Since you wish to run a contest, where a system stop would make you lose a lot of time, please be aware that prolonged system overload may lead to API failure. If this happens you would have to de-install and then re-install the RDSuno software as explained in my post:
