Should I just get a full-blown computer with a high-end video card to get around those problems? I already have the latest video drivers, so there's nothing I can do there. My wifi router is a Cisco e4200v2 so it's not that old and has decent bandwidth, so I don't think that is the problem.
If you search on my call sign you'll find a couple of lengthy threads about video performance issues associated with the 4000 series embedded graphics adapters that are built into many (not all) models of CPU's, both desktop and mobile. The most recent Intel drivers, dated since last September, show pretty good success in running SmartSDR. You can find the links to the Intel driver site in the previous threads. A recurring problem that a lot of people are having is that many OEM vendor sites, including Microsoft, HP, Dell, etc., roll back drivers, often to the version that was originally shipped with the PC/laptop. You have to go to the Intel website and download the latest Intel 4000 series graphics adapter drivers. If you use a vendor update site they will most likely roll your driver back to an earlier version. It doesn't matter which version of the 4000 series your system uses (4200, 4400, 4600, etc.) they all use the same download.
My high-end Sony laptop only started running SmartSDR some of the time since I installed the most recent video driver. Before that it would only run a couple of seconds and then crash. I have no problem running SmartSDR on Core i7-4770K machines with NVIDIA 760 video adapters.
We use the Surface in the games room attached to a projector - mainly to watch movies and Sky News (UK). But I do use it to display SmartSDR on the big screen too.
I have the same tablet, the Microsoft Surface 2 that was given to me at a Microsoft event last year. The Video drivers I use are from the Intel site and I have seen similar issues trying to run more than two pan adapters on this little thing. No so much choppy audio (I port through DAX), but more latency in the display.
I found that if I connect the surface via a USB/Ethernet adapter and eliminate the Wifi - the issue never arises.
Another thing you could look at is the QoS settings on your Router (if it has those) - I never bothered as it was easier to just plug it into the house network. But may be worth a try to see if you can up the QoS settings to give your surface a fixed IP using DHCP and then give it the highest priority on the network.
Flex is aware of the problems and is making slow progress. If more people are having performance problems, they may prioritize this work higher!
That isn't the case. We know you are crazy :-)
SmartSDR, when run on a reasonable PC platform with an adequate graphics adapter (using good drivers) will perform very well. I agree, a high-end gaming PC is a bit over kill unless you plan to crunch SETI data sets while chasing DX.
So far (knock on wood) no problems at all. Brought up a JT65 decode too. Maybe Intel finally fixed the problems that were affecting SmartSDR?
If anyone else happens to try this new driver, I'd be interested to see if it works better for you too. Hopefully it doesnt stop working as soon as I submit this post. :-)
Here's a link to the driver. https://downloadcenter.intel.com/Detail_Desc.aspx?agr=Y&ProdId=3718&DwnldID=23644&ProductFamily=Grap...

Edit: over an hour later, still no problems at all.
Edit #2: I'm declaring this bug resolved. SmartSDR (and the Intel drivers) haven't been this rock solid since I bought it. I'll give it 24 hours "just in case" but if nothing blows up, I'll probably post a new thread with this info just to catch the attention of everyone who has a 4000 series chipset. Tim - If you happen to see this and would prefer me to do something different, let me know. Feel free to shoot me an email or post here. This is awesome!! I love technology (sometimes lol).
You are a braver man than I should have been. The beta HD Graphics driver that brought success to your system comes with the following caveats and warnings, among others:
1. "This beta graphics driver provides support for two games: "TITANFALL" and "Thief". Do not update to this driver if you do not plan to play either of of these games."
2. "Intel does not recommend installing these beta drivers in systems used for mission critical operations or where productivity of any kind is a concern."
3. "These beta drivers are provided "as is" and are not supported by Intel Technical Support."
My high-end Sony laptop which will not yet run SmartSDR in a stable manner is a machine that I use daily on business matters. After some consideration and much trepidation I did a full backup of the laptop using StorageCraft and then I created a restore point.
Next I installed the Intel Beta HD Graphics driver. When the installation was finished I had no video on the laptop screen. I had a blank black screen. I plugged an HDMI monitor into the HDMI port to see if by chance their was video on that port. No joy. I used the function keys to change the monitor selection. Still, no joy. After numerous attempts all I had after Windows 7 Pro loaded was a blank black screen. Finally, I booted into Safe Mode and did a Restore to the restore point that I created before I started this process.
I am happy that you appear to have success with the beta driver. For all of the rest of us considerable caution is in order. I would caution that others at least do a Restore Point before installing the beta driver so you have an easy exit ramp to get out of the situation if it doesn't work.
I definitely agree with you that a restore point and backup should always be performed before any update, especially if it is a critical machine. All software updates (both beta and non-beta) come with risk that the user must be willing to accept before installing it. Most of the time updates run smooth, other times they break in unexpected ways.
There's also a new driver (non-beta) that came out in late January, I believe. I skipped over that one though since it was an older build number.

I'm running the January Intel driver. It is stable for all other purposes but it will only run SmartSDR for a short period of time before hanging. On the Sony laptop that is a big improvement because the earlier drivers would freeze in 1 or 2 seconds. Clearly, Intel is on the right path. In the meantime I continue to take the safe and easy road of running SmartSDR on high-end systems with fairly high-performance graphics adapters. When Intel finally fixes their drivers then my high-end systems will be overkill for running SmartSDR but that is not their intended purpose. They are intended to be used as skimmers monitoring all bands, etc. This is going to be fun. Multiple high-end computers connected to a FLEX-6700 radio server.
