Fusion 9.0.2 laggy interface after recent Windows 10 update

#1

Post by BigRoyNL » Thu Dec 20, 2018 12:48 am

We were noticing some machines started lagging in Fusion lately, where playback and moving around in the flow with nodes became laggy. It would stutter and appear as a jagged motion. Currently we are thinking this might be due to a recent Windows 10 update since around the times these machines got updated these things started to get noticed.

The machines vary in specifications, but some run 4x GTX 1080ti GPUs and a Threadripper CPU and others are dual core HP workstations with a single Nvidia GPU (like GTX 980 or alike). So I am unsure this related to a specific machine setup.

We were wondering if others have been seeing some recent speed changes in Fusion 9 on Windows 10? And maybe know how to solve (or debug) this issue?

Does Fusion recognize your Graphics Cards correctly?
If not, this might help: viewtopic.php?f=16&t=2690&p=20796&hilit=opencl#p20796

Investigated this - but the GPU was listed correctly and picked correctly. Also tried to explicitly pick one, no luck or changes. The lagging remain.

Any other ideas that could be worth investigating?

The lag is also present while just moving around the "Flow" editor with a single node in it, it stutters as you move around.

There is viewtopic.php?f=16&t=735 and viewtopic.php?f=16&t=1466 that you could try?

I haven't seen any lag issues with recent OS updates myself...

Ahoy there,
Me have a Threadripper as well. I had lags that would spike on my CPU almost randomly. It magically disappeared after a few days. Someone suggested that windows is still updating in the background. I was skeptical but it did disappear after 2 or 3 days.

Somehow we're still facing this issue on multiple machines now. Anyone else getting this on Win 10?

Maybe we should try and somehow reset Fusion preferences or get it to run in a debug mode to figure out what the hell is going on. Ideas?

Same here.

The problem appears even when I just hover the mouse over the menus. This occurs with Nvidia and AMD graphics cards.

The most recent Windows Update was the first to support the "Dark Mode" properly, both in the windows interface and in supported apps.
So they have indeed altered the way windows interacts with the application's interfaces.
Maybe this is the cause of the lagging.

I have already tried to turn off the dark mode, but it had no effect.

There's some activity with a proposed solution in a similar topic on the BMD forum: https://forum.blackmagicdesign.com/view ... ad#p466971

Not sure if it's the same lag you're experiencing.

Amazingly it solved the problem for me!
Thanks SecondMan

The question now is why...

UI lag

#10

Post by eski » Wed Feb 13, 2019 7:00 am

Just reformatted my computer and having this weird bug.

The UI is extremely slow! When dragging nodes around it will not follow the mouse one to one but skip frames and jerk around. Feel like this is happening all around windows actually but it's very clear when working in Fusion. I have already updated all drivers that I can think off. Never seen this kind of bug before, feels like the computer is working in the background and it is reflecting on the UI. The mouse is smooth when not dragging anything in Fusion but the moment i hold something down to move it will start lagging.

It's really frustrating to work like this, need it fixed. Does anyone got any tips? :?:

Merged with similar topic - there have been a few reports of lag in Fusion, hope you find a solution for your case up here?

Ah, I searched for this before posting, honestly... but this post just got past me.

Anyway, deleting the folder worked like charm... buuuuuut after working all day it gradually got worse again, so now it's back to the same lagging way. Really weird bug huh.. :|

Odd indeed! So what inside that folder causes the lag?

Maybe copy the contents before deleting it and then dissect what's in there...?

We had it recently, and it was the Fusion.prefs file causing the lag. We also have a situation where a drive that is mapped in the OS but can't actually be accessed (it's a RAID that's rebuilding) causes the issue. When we disconnect the drive through Windows Explorer the lag vanishes. I haven't been able to narrow it down any further than that or do any kind of systematic testing.

The question is, what is it in the fusion.prefs that is making this happen. Can't find anything obvious in the file that would be doing it..
