v9 performance drop :(

[Dean Manion]

I’m seeing a significant performance drop with dynamics. I used to be able to play through iris fixes just fine and now it drops to a ridiculous stutter no matter what I do. It makes it untenable for screening anything. Any kind of key framed adjustment slows to a stutter. Very frustrating.

Mario,

Would it be possible for you to send us an export of your project from Resolve 9.0.1? You can send the exported file to davincihelp (at) blackmagicdesign (dot) com.

Thanks,
Anish

DPX Render Benchmarks – V8 vs V9

I use Resolve Lite to consolidate our various projects, converting Alexa ProRes 444 to 10Bit DPX.

Version 8
Averaging 35-42 FPS

Version 9
Averaging 15-17 FPS

Regarding Pauls post, I did a test here to see what differences occurred. This was on a 5,1 MacPro with dual 2.4Ghz 6 core Xeon CPUs. 12 GB of RAM. OS X 10.8.2. CUDA 5.0.24. A single GTX570 graphics card. DeckLink HD Extreme 3D+. Using a ProRes422HQ HD source file. One node with a Primary correction. HD timeline. Rendering to a ProRes422HQ file in HD.

Render Speed Results:
V9 Beta 1: 76 FPS
V9 Beta 2: 76 FPS
V9 Beta 3: 76 FPS
V9 Release: 76 FPS
V9.0.1: 76 FPS

I also ran the Standard Candle 82 test with all the above versions. There were no performance differences between any of the versions.
All Node tests realtime 24 FPS except 12 nodes, which was 14 FPS.
NR4 = realtime 24 FPS. NR3 = 21.5 FPS. NR2 = 10.5 FPS. NR1 = 3FPS.

Regarding Mario and Anish’s comments, it doesn’t look like we’ve received a project export to examine yet.

wow Dwaine. That is incredible performance with just the one gtx 570.
I had to run my system that way while my cubix was in for repair and I was getting mid 30’s on prores 1080 render on an almost identical system (although my storage is an external 8 drive sas getting about 650MB read/write) – I assume you had local storage on the mac pro…

on another note, I just did my first supervised job with a single long file cut up or “notched” at the edits, :60 tv spot. normally i have edited original source media or media managed projects with separate clips for all shots.
I had dismal performance on my full blown mac system with 3gpu. barely could play 23.98 1080 prores realtime.
is this normal behavior? does resolve not like media handled this way? (ie it was a self contained movie in FCP, one clip cut at the edits, and xml sent to resolve, only 60 seconds long – basically a “pre conforming flat media to EDL” type of workflow)
It seems I’ve done this in the past, but this was kooky bad.

Edit.. Maybe I was seeing the new “window tab open” bug?

Im in the middle of project so I cannot revert back to v9 but issue is not in single project.
All projects, old or newly created ones are much slower.

One thing we may not be factoring in is the 10.7.5 OSX BUG.

when i updated i carefully read the config requirements, and updated to 10.7.5, which was a BIG mistake, because the Spotlight indexing was severely broken on that build, meaning that if your system started indexing, it would NEVER stop, using precious CPU resources for nothing.

I reported this to Apple who promised a quick fix.

THIS MORNING Oct 5th they released a 10.7.5 PATCH which has fixed the problem, so now i hope my system will be more responsive.

Did a test using Resolve 8.2.2 and the Standard Candle Test 82 using the same hardware and software as mentioned in my earlier post about V9 version testing. All my results in 8.2.2 were identical to the V9 results.

While I had 8.2.2 loaded, I also repeated the render speed test that I performed on all the V9 versions above. There was a big difference here. Instead of the 76 FPS render rates of V9, I got 25 FPS render rates in V8.2.2. Many people have commented about improved V9 render speeds, and that certainly is true on this hardware.

I was having a nightmare of a time with performance loss –
32 gb ram, gtx titan gpu, amd phenom 6core – but then like an idiot I realized that I had the ‘Proxy on the Fly’ selection check-boxed.
I believe this writes cached files of the media as it plays to theoretically allow for faster playback later on. The problem is that it has to constantly re-write if you are still working on a project, so rather than just reading the media, fps was caught up on writing it as well.
Check to see if ‘Proxy on the Fly’ is selected. If it is, try de-selecting and see how your performance increases. I was working on a 5k feature shot on Epic. Performance was down to 8-12 fps with only five or so nodes and an alpha on each clip. Unchecked ‘Proxy on the Fly’ brought my Red playback up to 20fps instantly.
