    Hi guys

    I know this has probably already been asked a thousand times, and I’ve been scrubbing through old posts and articles. However, nothing seems to work properly and i’m still learning so excuse my ignorance.

    So the issue is, I’m experiencing very slow playback in resolve. Usually the machine gives an average of 19/20 fps (not ideal but ok), and lately the average is about 10/15fps, bordering on 5/10 fps for heavily graded shots…

    I don’t understand what’s going on, I’ve tried tweaking the system and resolve preferences, project settings, everything, and the playback always comes back much more slow than it used to.

    Here’s what I’m working with:

    Mac OSX 10.9.4
    2x 2,66 GHz 6-Core Intel Xeon
    8GB 1333 MHz DDR3
    ATI Radeon HD 5770 1024 MB

    And resolve is working with Quadro 4000

    Is it the ram? The driver? Do you think there’s any solution that doesn’t involve upgrading the RAM/Graphics cards? My main issue here is that while not perfect, the playback was at least better than this and more acceptable, and it only had lag in very heavily graded shots, while now it’s basically like this in every shot.

    Thanks in advance!

    I have found recently I get pretty poor performance on my mobile rig with that card in resolve when splitting. So I went back to my GT120 and Q4000. I’m locked into mountain Lion though and have a boatload more ram.

    The published config guides, on our support web site, have the answers. The GPU is low power and the system ram too little to start.

    What Peter said of course, but let me also remind folks that Quadros are weak on Cuda cores. The GTX gaming cards work better for Resolve.

    Quadros are for 3D graphics/VFX.

    Y’all be cool,

    So, as I imagined, no solution besides upgrading my hardware right?

    Also, Peter, looking at the configs I figured my machine was too weak to start with, what had me asking was mostly deviated from the sudden drop on performance.

    Thanks anyway!

    Did the issue start with 11? In other words, it was better in 10?

    Maybe a OS X update started the issue?

    Did we mention you want to probably have the latest Nvidea Web Driver and Cuda. Also some BMD Desktop versions work better than other depending on your particular setup. Assuming you have BMD Desktop.

    Hang in there,

    The issue came up with 11, however I wasn’t grading on this machine with 10, and when I asked around in my facility, no one knew if this was a problem with 10.

    I do have Web Driver and Cuda up to date, and there hasn’t been an OSX update.

    I followed your advice and playback is slightly better now, after I messed around with BMD Desktop, and a couple more settings in Resolve. It’s not ideal, but at least is workable until we can upgrade!

    Thank you for your help!
