Davinci runs slow

[Rick Van den berg]

thanks for the replies, i tried some things like changing the debayer settings, but its still slow. i guess i gotto get an Nvidia card then. i understand why this is, but its still kinda frustrating since applications like apple color and speedgrade all work just fine..

Apple Color was never really a real time app and Speedgrade is using different technology, so comparing Apple to Resolve is like comparing apples to… well you know:-)

Hello. I’m using DaVinci Resolve Lite on a Mac running on Lion 10.7.5 (my Mac can’t be upgraded to Mountain Lion unfortunately), I’ve got 2 x 3 GHz Dual-Core Intel Xeon processors, 16GB of RAM, and two graphics cards, one for my monitors, which is an NVIDIA GeForce 7300 GT 256 MB and an ATI Radeon HD 5770 for DaVinci. I know most of you agree that it’s not good enough for Resolve, the thing is I bought it specifically for it when it was still Resolve 8 and it was said to be supported by Resolve. And it worked fine.

I’m now using Resolve 9.1.3 and it was still working fine until halfway through a 3 minute project. One second it was fine, and the next it was running extremely slowly. Any change now takes 3-5 seconds to appear, moving a window is painfully slow… I’m now on another project and it’s still running just as slow. I’ve updated all the drivers, and I don’t know what else to change. If it’s just the graphics cards that can’t handle it then fine, but why was it working fine until recently? Nothing changed in between, I don’t understand.

Any ideas?

Hello Erline,

Did you find a solution to this problem of the project suddenly running slow on you? I have hit this brick wall also and can’t figure out why. I have tried freeing up space on my drives, though that doesn’t seem to be the issue.

Software was running flawlessly until this morning – nothing apparently had changed.

Hope you can shed some light on this!

Best,
Tom

Found a solution…

Somehow it seems the project I was working on became corrupt. So I started a new project, copied across the grades using the COLOURSWAP options and now I am working back at normal realtime speeds again.

Best,
Tom

Hello Tom,

No, I haven’t found a solution. And it’s not just this project, Resolve in general is painfully slow (I have to wait between 5 and 20 seconds for any change to appear, even with one single node and only adjusting the gain for instance). I tried creating a new project, with different footage, updating drivers, reinstalling DaVinci etc… No luck.

I have decided to buy a new computer, which I won’t be able to do for another few months, but I think my old MacPro has to be part of the problem, although it doesn’t explain why it was running fine and changed all of a sudden, halfway through the day.

Sorry I can’t help you.
