Hi everyone again.
To answer several posts in one:
1. We'll try to release it before the ARRL DX CW contest? (19 Feb), at least share it with testers.
2. Adapting new firmware for ESDR2 may take a month or even more, at this point it's a waste of time.
3. As far as I know ESDR3 works way faster than ESDR2 and requires fewer CPU resources.
So the issue described by Bob KD8CGH might be in the API used for ESDR3 display or overall CPU load with other third-party software.
It's not normal and should be addressed closer to the release of ESDR3 1.0.

As far as third party and other apps running, I have done several videos of V3 there posted on YouTube and a few within the EESDR site as well

As far as apps and third-party software running when doing most of those videos included SDC, a logger (LogHX 5M contest, Swiss log, Log4OM or AClog) my Outlook email a web browser and at times those alongside a digital mode and more importantly OBS studio have been running on the same PC and with 2 or 3 monitors. Using Vulkan I see a slightly less resource loading and a better overall framerate compared to DX11. DX12 may prove better then DX11 but at this point it hasn't been implemented yet in V3. in any of those videos I never had a lagging experience in V3 when showing adjustments or going over settings and using the rig.


I also have use NVidia Graphics card an older 1050Ti have not experienced that- Curious as to which Graphic card Bob is running? and what driver
One thing I have noticed is the Studio drivers for NVidia are less resource intensive then the gamming driver (Go Figure).

Also performing a CLEAN DRIVER install may fix that issue- NVidia Drivers and updates are horrible!

Thanks everyone

I updated the drivers for the NVIDIA MX150 using the gaming choice and ran many tests with only SDR3 running. Top take aways:

ExpertSDR3 uses about 27% CPU, 26% RAM, 8 Mbps Ethernet (156 k sampling) AND 22% of GPU0 - the Intel UHD - it doesn't use GPU1, the NVIDIA MX150.
I see the same behavior with all three API choices.
SDR3 is slow to start and displays "not responding" in the window title bar
When I touch a slider the app freezes for a few seconds, then the slider moves freely until I touch another widget, after which the slider starts over with another freeze.
The sliders move as expected using the mouse scroll wheel.
On exiting SDR3 and the launcher an SDR3 task is left behind that has to be cleared by the task manager before SDR3 can be restarted.

By comparison, SDR Console, which performs the same functions for the Hermes Lite 2, uses 17% CPU, 25% RAM, 15 Mbps Ethernet (192 kHz band width) and does use 14% of GPU1, the NVIDIA card

Seems high, what are the full system specs? EVEN for the HERMES your system resources are high
as example and this is with a lot of other stuff running as well as you can see in the snapshot

EESDRV3runningplusothers.jpg


Two monitors as well at 2560X1440 and EESDR sample rate is maxed

EESDR3SampleRate312.jpg


System is AMD Ryzen5 3600 6core 32GB ram System drive and drive for EESDR is a Samsung 970 M.2 SSD- video 1050Ti operating system as shown below

BOB, looking the specs on the Intel processor I see it's a MOBILE processor. So is this a SFF desktop or perhaps a laptop?

My guess given what I know about your system so far is you may have a LOT of DRIVE CACHING going on and a slow performance hard drive bottlenecking some of it,

I'm going to assume its a standard rotational drive most likely a 5400 RPM and perhaps part of the problem?
can you share the hard drive and the ram speed info? Just trying to help figure out what may be going on

Thanks. Yes it is a laptop and I have an external monitor attached. It does have a hard drive. After loading SDR3 there is almost no disk activity.

I'll go out to the shack later and get the specs. Meantime, the big difference that jumped out at me was that SDR3 is not using the NVIDIA GPU and SDR Console is. Although SDR2 also doesn't use the NVIDIA and runs well.

Based on your comment I also did a "clean" install of the NVIDIA drivers.

Disable the INTEL UDH and then everything will use the GeForce- Also You mentioned you installed the gaming drivers, personally from what I have experienced the Studio Drivers seem to give better performance for these applications.

Also do you know what TYPE of hard drive is in it,
I can tell you if it's a standard rotational platter Drive switching to an SSD will make a big improvement!
not only in loading of the applications and operating system but in overall system performance

Another possibility maybe your AV, what AV product are you using? Some like Norton and McAFEE are very bad resource hogs!

NVIDIA doesn't release a Studio driver for the MX150.

I'm just using Windows 10 AV.

Again - there is very little disk activity while SDR3 is running.

I'm concerned about disabling the on mainboard graphics and winding up with an unusable, bricked laptop.

SRDC and my image processing software use the NVIDIA, so it is accessible and usable for apps that call it.

Big SDR3 items are freezing when I touch a slider and leaving a zombie SDR3 background task after exiting both windows.

The slider problem seems to be one of focus. After SDR3 unfreezes the slider moves as expected until I touch something else. BTW - only the SDR3 display freezes, the audio receive continues and other apps are unaffected. The GPU use goes to near zero while the SDR3 display is frozen. Since the network and compute intensive decoding and everything else continues to work that suggests to me it's a UI problem and not any resource limitation.

More experiments.

I loaded SDR3 on another Win 10, I7 laptop. On exiting SDR3 also leaves a zombie process behind on this machine too.

SDR3 does not freeze when you touch a slider on this second laptop. So there is some difference that causes the problem on the original laptop. Unfortunately the original laptop is my ham shack computer so I would like to find a solution.

Uninstalling and reloading SDR3 on the original laptop does not help. It still exhibits the same display freezing.

I found that you can control individual apps from the NVIDIA control panel. I forced SDR3 to use the MX-150 rather than let it decide. Task manager now shows that it uses the MX-150 GPU, but SDR3 still exhibits the display freeze when a slider is touched.

Hi,
Quick update : Only one modification helps to fix the audio pops issue : modify the registry (related to UDP packet)
Thanks for that. 73

Glad you got it working well.
That wasn't enough for my case and I had to also back off the sampling.

Where can I find instructions for this registry mod?

Here is the info I used from N8SDR

https://eesdr.com/en/forum-en/other-questions/9085-possible-help-for-those-experiencing-audio-drop-out-on-windows-10-systems#18348

I think changing the sample rate made the biggest difference for me.
