I started to see that also in 16, but less aggravating.

here is the video https://www.dropbox.com/s/gn9f9gtn2ucd6o1/DaVinci%20Resolve%20Studio%20-%2001_helene_doomed%202020-12-20%2008-54-37.mp4?dl=0

the piece is a 3 minutes music video, a single clip with cuts and color. it take seconds to simply switch pages.

I have been seeing longer than usual times when switching to a new page in Studio 17 for Windows.

I thought perhaps my older hardware was the cause.

17b6 does not improve the issue.

I think I am seeing improvement in Beta 6. Going to Fusion is slow, but the other pages do seem to load faster for me now.

Switching pages is no more than a half second for any of my projects in R17 on Mac Mojave.

Do you happen to have a graphics tablet connected to the computer (like a Wacom or a Huion) ? I have a Huion tablet and if I open Resolve with the tablet connected to the computer, tab switching and even opening settings, the inspector etc is much slower compared to when it's not connected.

Thanks, yes i have a Wacom, i will try to uninstall it and check.

I've been having this issue as well with all the 17betas. I can confirm, disconnecting a wacom and starting resolve and then reconnecting the wacom makes a staggeringly better experince in switching tabs.

I'll keep trying different approaches, and maybe a new wacom driver, but this is a dramatic improvement in performance from a gui perspective.

On my machine (Resolve is installed in a VHDX on HDD, so disc access is quite slow compared to production systems) with Resolve 17b18 (and Wacom 6.3.39 drivers):

Startup with Wacom Intuos Pro disconnected (from start of the log up to 1st «Flushing GPU Buffers»):
about 47 Seconds.

about 26 Seconds.

Measuring the page-switching time is inaccurate. Especially the Fusion page needs some extra time after being drawn onto the screen until it accepts the Shift+6 for switching to the Color page. After opening the "Age of Airplanes" example from the beginner's guide into the Media page, I did nothing but switching pages manually as fast as possible. Measure is the difference between the "Main view page is changed to ..."-entries in the log, then in the %APPDATA%\Blackmagic Design\DaVinci Resolve\Support\logs directory (requires Windows-Subsystem for Linux, or a Linux- or a OSX-machine, respectively)

Code: Select all

cat ResolveDebug.txt | sed -n -e '/Main view page/p'

Page-switching time with Wacom Intuos Pro disconnected to USB:
from about 1 to about 3 Seconds.

Page-switching time with Wacom Intuos Pro disconnected from USB:
from about 1 to about 3 Seconds.

Page-switching time with Wacom Intuos Pro reconnected to USB after being disconnected for startup:
from about 1 to about 3 Seconds.

Conclusion: Disconnecting the Tablet speeds up the startup, but has no significant influence on the page-switching time.

For me, starting up Resolve with the Huion tablet connected, tab switching takes 1-3 seconds and other options like project settings and inspector take 0.5-1.5 seconds.

Starting Resolve with the tablet disconnected, everything is pretty much instantaneous (possibly the fusion page could occasionally take a bit longer).

I can confirm that for me unpluging wacom intous BT S solve this BIG lag.
I am using DR Studio 16.2.7 on Win 10 Pro.
