Davinci Resolve Studio is suddenly super laggy

Hello,
Two days ago I was putting together a project (wedding film) within Davinci Resolve Studio 17 (latest update installed).
Everything worked fine.
Then yesterday I wanted to continue the project but the entire program is suddenly super slow. There is almost a constant delay between me clicking on things in the program and the program reacting like 5-10 seconds later.
I have scoured the web looking for answers but couldn't find anything that could solve my problem.
I updated to my latest nvidia driver (studio 462), I even downgraded as far as 430 but they both don't seem to work.
I also tried updating my normal windows updates. Nothing seems to work and it's driving me insane!
I have a deadline for this wedding which I intend to keep!

I also already sent an email to Blackmagic support to see if they know anything.

Anyone else facing this issue or having any idea on how to solve it?

Try, un install the GPU driver
Do a complete new install, not update, of the current GPU driver for ur GPU.

Hi Peter,
I tried that as well but to no avail. I used the recommended DDU uninstaller method. So first uninstall all nvidia drivers and then cleanly install the current ip-to-date driver within safe mode...

Time to generate and post logs as per the fAQs

I have the same problem. Mine started yesterday out of the blue, while I was working on a project. It just started happening for seemingly no reason.

You didn't provide your system details, as per FAQ recommendations, so im guessing you are on Windows and it did an update that messed up your GPU driver.
so,

Davinci Resolve Studio 17.2.1 Build 12

PS: As I post this, Davinci Resolve seems to work fine again... I'll keep an eye on this forum and report back if the problem comes back or stays away. I'm curious if there is anything you can find in the logs.

Thanks for the help!

Update: Just now it was experiencing the same problem again. I noticed that my speed editor was not connected as the lights were not on. I exited the program and reconnected the speed editor and restarted Davinci, simultaneously pressing buttons to make sure the red lights on the keyboard were on. Now it seems Davinci Resolve is working smoothly again.

Could it be that the failure to connect to the speed editor might be slowing the program down?

Yes it is the speed editor that is causing this problem. I have the same problem too.

Is there a way to properly "Do a complete new install, not update, of the current GPU driver for ur GPU."?

When you install the NVIDIA VGA Studio Driver, there is a checkbox in the installer to do a "clean install". Is that what you mean Peter?

Hi Csaba,

Refer to this link for a clear explanation: https://crinrict.com/blog/2019/02/clean ... r-ddu.html

The only thing you need to do differently is download the latest driver first and install that in Safe Mode after you did the uninstall. Only connect to the internet after you installed it or disable automatic Windows driver updates.

If Google search "Clean GPU driver install DDU Windows 10" you'll find plenty of articles!
