Low FPS with AVC

[AndreasBR]

Hello everyone,

we´re using remote boost internally so far. Here we use the "old" codec, bacause bandwidth is not an issue. Now we´re testing over WAN where we connect via VPN into our facility and then RGS onto the Z4. Here we´re testing with AVC, but the refresh rates are very erratic and in total never at min 25 FPS (What we need). Using the old codec we get stable 25 FPS (set in the min Refresh setting) solidly. We tried with HP velocity and without. Same problem. And under statistics we can´t see any values for velocity. I think this i probably connected to using a VPN.

What could be the bottleneck for the low refresh rates with AVC? The encoding is set to GPU and the graphics adapter is a P4000. This should be suffiecient, or? At least we don´t see too high loads on it when remoting. Roughly 25% GPU load. 

We also tested it against a HpZ840 with dual 12 Cores 128GB Ram and another P4000 (not sure about the exact model right now) Same dropping in refresh rates. 

Tools used on the senders are Adobe CC and Avid Media Composer.

Receivers are a variety of HP Elitebooks.

Any help would be great.

When you say old codec, are you referring to HP3 or Lossless?  Have you checked to see if maybe through your VPN connection that bandwidth is not being throttled down?  What are network conditions on the end user side?  Any speed tests done during a connection.  If possible, it can be helpful to pin the Receiver Tool bar so you can see both bandwidth and fps at the same time.  There is a Remote Boost configuration guide which has a section on performance tuning.  I have attached it here.  Will reach out to you on private message to gather more details, logs.

Hi Kelly,

we´re using HP3 as "non AVC" codec. I checked the bandwith and yes, there is a throtteling, but would this not rather be a problem for the higher bit rate HP3 than the AVC?

We´re monitoring the bandwidth and FPS via the Tool bar. 

I retested it with another, smaller Z4. Here we have stable Playback Rates of 25FPS with AVC enabled. The difference though is that this Z4 is in headless mode. The standard EOID ZRemote boost seems to be using,  is simulating one 16:9 monitor.

This would be one difference compared to the other Z4 and another Z840 which both show the same low refresh rates. 

All three senders are in different subnets on our campus. 

I checked the GPU load on the problematic Z4 right now and it was running at max 21% with AVC enabled. So I would not assume the GPU to be the throttle. 

I´ll answer to your PM too.
