Thanks for all the answers. I'm on tour atm, not near a projector before tomorrow.
R5 tied it's frame rate to the GPU's refresh rate as well.
There's nothing new here.
Not for me, R6:11fps, R5:90fps on the same hardware setup.
I tried that, in this Intel Radeon dialog where you profile each software. It had no visible effect. Framerate remained super low, yet there is massive tearing either way. Seems I got the worst of both worlds.
Also, If you monitor or projector can only do 30 or 60, what advantage is rendering or pushing out anything past that? The output device physically can't use any of that.
a) See my second post with the Atomos. Huge issue, as the slowest device pulls down everything else.
b) Whenever a clip is triggered the framerate briefly falls below the ideal 30 or 60. This stutter is visible and could be avoided with Res running faster. Of course not at the price of screen tearing...
Sounds like a driver issue to me.
Brand new laptop, everything was as uptodate as Dell Updater knows.
I bypassed the Dell Updater by now and manually clean-installed the latest available drivers, will see tomorrow, but I don't expect any improvement. Just a belly feeling.
I don't use AMD so I can't offer any advice on that stuff. For me nVidia has been rock solid.
My old XPS15 has an Nvidia card inside, a 750gtx. Drivers are uptodate, yet I have the same problem, just not as bad. (Framerate falls to around 20fps with two external projectors connected.)
For starters I don't get why the issue only occurs with projectors in live situations, but not with the two monitors in my studio. Everything running at 60Hz. Shouldn't make any difference, no?
Seems I'm cursed.
Zoltan, yes, you are right, there is still a Intel GPU on board. The strange thing is, when I run Resolume both GPUs go up (in Win10's Task Manager -> Performance view). Intel GPU goes to around 30%, Radeon GPU to whatever the workload happens in Resolume. With no external displays attached, no frame rate limitation set and a few clips running, I can drive the Radeon GPU up to 98% while having some 100something fps.
I use a TB3 dual HDMI adapter, it runs through the Intel GPU and I have to configure it accordingly.
Maybe that's the cause? You configure it via the "Intel HD Graphics Control Panel", right? There doesn't seem to be much in there. Vertical Sync can be set to "Use Driver Settings" .. but what are the driver settings? It doesn't say.
