话题: Slight freezes on MacBook Pro
I’m using a 2022 M1 MacBook Pro with the latest stable of VDJ. The last couple of weeks I’ve noticed that both on my Mac and on my Denon Prime 4 screen everything freezes for about a second (the music keeps playing). It happens very randomly when browsing, or when doing nothing apart from the song playing. The only thing that has changed is that I’ve updated to the latest MacOS Ventura. Has anyone else experienced this?
I’ve closed any programs that are running, turned off. Wi-Fi, turned off Bluetooth.

Controllers - Denon MC7000, Denon MC6000 Mk2.

Still an issue though Les. Several people have reported this now and I definitely experienced it during tearing.

@Adion?

I think I’ve solved it.
Things I tried that didn’t work:
Changed various FPS for skin and video
Changed cables
Tried Virtual DJ 2021
Tried different skins

This is the thing that appears to have fixed it (fingers crossed). I went into the display settings of the Mac and turned off Pro Motion and set it to 60hz.
It’s been fine now for 3 hours.

Could the engineers do a bit of testing around this for future releases?
Many thanks!

Weird one as Les has the same 120hz display but no issues.

Yeh, but after experimenting I found that having my videoFPS set at 120 is a lot smoother than 30 or 60 FPS.

As I posted in another thread I set the skin fps to 0 and that seemed to help. Not sure if that uses the display native refresh rate or not.

Here is that demo again;

Demo of 14" M1 MacBook Pro

Running a music video on VDJ and several other programs at the same time.
You will notice that the scrolling text is moving across the screen smoothly.

It was suggested many years ago by Don Moir (TellyVisuals) to set the videoFPS at either the screen refresh rate or multiples of it, that's why I tried 120 FPS and it works for me.

I had tried putting the skin fps to 0 and the issue still occurred. My video fps was always at either 30 or 60 when I was trying different things so was always a factor of 120. The thing with ProMotion is that the refresh rate is always changing to suit the need. ProMotion means that the refresh rate is constantly changing. Maybe this variable refresh rate was causing the issue?

It's a possibility. If it works now then great.

I got a gaming laptop with both 165hz and 60hz but I just set it to 60 as the smother screen display makes no difference to me whatsoever.

The Mac variable rate may indeed be the problem. Maybe Adion could chime in here.

Another night without the issue, I’m convinced it’s to do with ProMotion.

Good morning. I too have experienced this issue after the Ventura Mac OS upgrade. I also use a prime 4 and did the latest firmware at the same time. Prior to both these changes everything was rock solid. I have made the adjustment mentioned here about the pro scrolling of the display and will report back after tonight’s gig. Fingers crossed.

Hi Dennis - did it work?
