I've been experiencing some random drop frames when using full screen playback. 

I have two graphics cards in my PC. One is GTX 1070, other one is AMD RX 580. 

My footage is encoded in DNXHR SQ. I've tried transferring it to an SSD, to iron out the data speed bottleneck possibility.

The only card I get dropped frames on is the GTX 1070. As I said, completely random. Never in the same spot. I'm also using the driver version Avid has recommended for these cards.

Tried doing full screen on the AMD RX 580 and I get screen tearing (although no dropped frames). I've read in the last update that Avid supposedly fixed this issue. Not for me though. :))

Another thing I've tried was to connect a BM UltraStudio 3G through TB3. Playback is silky smooth in this case, never dropped a single frame.

I'd really like to have the option to use both of my screens for bin real estate, but also use one of them for full screen playback when I need it.

The output card gives me great results but I'm losing the screen real estate and I don't have a third monitor.

Anyone had issues like this before? I wonder if there's a fix for this, either the GTX or the AMD.

Thanks!

Hello, 

I have a couple of things you could try. 

Firstly, Have you tried another version of Avid Media Composer? It could be a very specific bug/issue with your driver version and that version of MC. I would try to go back to an old version, something like Media Composer 2018 just for the sake of troubleshooting. 

If that doesn't work, Go to the Avid Console Terminal and punch in "FSP Locked". That should lock the full screen video output to the monitors vsync. Try it, and let us know how it goes. "FSP Unlocked" is the command to undo that. 

Good Luck!

Thanks, Philip!

One thing I did was set "Wait for Vertical Refresh" to always on in AMD settings and I got no more tearing. I've done this in the past but had no effect. Don't know why it worked this time.

Then I went and turned it to "Off, unless app specifies" and getting tearing again.

Then turned FSP Locked on, still getting tearing.

Turned "Wait for Vertical Refresh" back on, no more tearing.

Still puzzled by why the Nvidia card can't get smooth playback at all. It's not constantly dropping frames, just here and there and it's not one or two frames, it's 4-6, pretty noticeable and annoying.

Fun fact, not that it's something anyone would do but having the full screen display connected to the AMD card and the other one to the GTX, the drivers sort of crash while playing with full screen on. The way it crashes is that the record monitor on the display with the UI goes black, then back on, etc. The full screen display also flashes black. Of course, putting both displays on the same card fixes it.

I haven't tried installing MC 2018 yet since I'm in the middle of a project and I have limited time to troubleshoot.

Thanks for your help, Philip!

No worries at all!

I think another issue is the fact that you have two GPU's from two different manufacturers, running one avid media composer system. It could be just confusing something. These systems are complicated, there are like millions of reasons why it might not work as expected. 

So just to confirm, have you got the AMD card to work? 

Yeah definitely not ideal to have GPUs from two manufacturers. I will try with the GTX alone for testing sake but I'm pretty confident i'll get the same results.

Yes, the AMD card works just fine for my needs.

Off topic : To get into more details, the reason I have AMD and Nvidia GPUs in the same unit is because I also run a OSX on this, a Vanilla install using OpenCore. This basically installs OSX natively without changing any of the system files and is more stable than ever.

As you probably know, OSX is only compatible with AMD cards at this point and Nvidia driver updates have stopped after High Sierra.

As we're talking about playback here, what I've generally noticed as a difference between OSX and Windows, no matter if we're talking about hackintosh or real macs, on OSX it has a longer delay between the moment you hit the play button and the moment it plays, no matter what.

I've tried testing on several different macs, on different versions of avid, with different storage, etc etc. Results are consistent with macs and I never get that snappy feeling I get on Windows. Do you get the same experience?

Oh I see.

As a student, I've never been able to afford a MAC system, so have always been on windows. I used to use the full screen playback feature out of my Nividia GTX 1650, but I ran out of HDMI/DP out ports on my GPU, so in addition to that I now have a Decklink Mini IO card plugged into a couple of monitors (and hopefully scopes soon). I get no lag whatsoever with either the decklink card, or when I was monitoring through my GTX.

The only experience I have with MAC is when I go into post houses or at my university, and these systems almost always have a I/O box anyway.
