Mac OS-X 10.8.3

[Simon Blackledge]

Got a Mac Pro 3.1 running Resolve in a room with a GT120 and a GTX285

gfx card popped in a vfx macpro so popped the GT120 in to keep em going to replacement comes.

Resolve is now running better. Where I used to get 23/24 fps with DPX am getting 25 properly now.

Single 285.

Ordered a GTX670 FTW which will go in 3,1 then the vfx guy can have the 285.

Juan.
I’m running 10.8.2 on Mac 4.1 with GT120 and GTX570 3GB. On FCP 7.0.3 I run Baselight Editions, Twixtor and even Neat Video among other with absolutely ZERO problems. Never EVER I had even one dropped frame. Your account of dropped frames as a result of simply use GT120 makes no sense, as FCP doesn’t use ANY GPU acceleration. Of coarse your GT120 may have a problem, but it doesn’t mean, that ALL GT120 do.
Sorry, but your “facts” are old wives’ tale not based in fact.

I tried to remove GT120 and use just GTX 570 3GB. As a result Resolve’s performance dropped down considerably in comparison to just a single GTX 570.

My facts, are based on personal experience and convos with engineers at Apple. I’m glad the combo is working for you. I also use the gt120 for gui one of our boxes, but we’ve stopped using said box for FCP. It just wouldn’t play through a sequence.

I wonder, do you do tape mastering from FCP? Do you have dropped frame warning on playback enabled?

I’ve seen it first hand where an fcp install on a box with gt120 gui wouldn’t playback without dropping frames, switched out gpu, 0 dropped frames.

I’m well aware FCP doesn’t use GPU computational acceleration. But it does use openGL and the graphics buffer to draw the frame on your screen, which is why fcp requires Quartz Extreme. So there is a reason for it. I’m sure a software fix could be implemented, but I wouldn’t hold my breath for one, considering the card’s age.

BTW, it’s not just me:

And of course there are plenty of people who can’t figure out why their system is dropping frames, all of whom have the gt120, here is one such case. But these pop up all the time in the FCP forum.

Did you enable “Use optimized display mode durring playback” as is recommended for single card configs?

That’s interesting. Many other people have had a different experience. I wonder what the difference is.
FCP 7 isn’t officially supported on Mountain Lion, so it makes sense that there will be various issues, which Apple won’t fix.
In any case, once BMD qualifies the 7750 and 10.8.3, that card will probably be much more powerful than the GT120 for other apps.

I had problems with the GT120+DavinciV9+Prores: https://forums.creativecow.net/thread/277/22659

If I change anything (using davinciV9, or pulling out the GT120, or using any other file format), it works.

I am thrilled that I upgraded to 2 gtx 580 classified ultra in a DIY cyclone expansion chassis for render. Put my 480 in for the GUI and did the After Effects and Premiere fix, WOW! GUI flys and AE renders are really speeded up, not to mention Resolve FLYS, makes a huge difference on 90 min shows with multiple nodes and NR at 1 or 2.

Anyone want my 120, will be ebaying soon, after this thread I’ll get $10 and shipping!

By the way, the Cyclone folks are great, pre sale and post sale! Also nice you can buy the components. I had an old ATX case and a new power supply and only had to buy the back plane, interface card and cable.

MacVidCards was great as always.

Before updating to 10.8.3 and the new CUDA driver, I had some choppy playback problem with my config:
GT120 and GTX570 export was fine but not real time playback.
Now with the update, I get full playback with that kind of nodes (just for testing):

out of my C300 file
which was never possible even with 2 or 3 simple node stuff before.

I’m using resolve to transcode Ikonoskop cinemaDNGs to MXF DNxHD 1080p 36 8 bits at edit house request.
I was on 10.8.2, and stupidly updated to 10.8.3, and now I swear I’m running much slower. Anyone no any way to revert or what I’m possibly doing wrong? I don’t have timemachine on. I’m running on average 10-18fps. I was getting realtime and faster (24fps and up) playback. I’m on a job currently, and this is screwing me, so any help asap would me very much appreciated.

Also, I noticed and not sure if it makes a difference, but under preferences it only displays my 570 as gpu. Says nothing about ati radeon as gui, but my mac recognizes it. To make it work, I’m running external power to it.
