Decreased performance with 8.2 install

[Juan Salvo]

Running lion. No difference.

[Ola Haldor voll]

I’m on Lion 10.7.2
No difference in performance here.

Have you filled up your hard drive? Is RAM filled up? If you haven’t, try a complete shutdown and restart the computer.

I find that shutting off the computer completely solves most problems rather than a reboot. But that only happens once or twice a month.

yep

More or less the same problem, here in Holland.

Harddrive A has OSX 10.6.8 and Resolve 8.1 and plays back 18 nodes at 25 fpm (1080p)
Harddrive B has OSX 10.7.3 and Resolve 8.2 and plays back 6 nodes at max 22 fpm.

Both systems have this AGPM. kext thingy removed, the only difference is that i accidentally (?) updated my cuda driver at harddrive B (os 10.7.3). Harddrive A has still cuda driver 4.0.50.

I tried to change systems and versions because in OSX 10.6.8 Resolve always crashed when i wanted to render to anykind of DNX code.

answers and explanations are more than welcome

(I would have bought the dongle if someone could guarantee that it would resolve all problems)

Perhaps the newest nvidia drivers and update Duda will help?

Your dual boot setup does leave the question though as to whether the 8.2 update itself is causing the issue in Snow Leopard. It would be interesting to see what happens if you updated the 8.1 snow leopard install to 8.2. I don’t want you to wreck your system though. Two other things we do have in common is the removal of the power management next and the graphics card – I’m using a flashed 470 as well. I have another partition set up with Lion I may try it there and see what happens.

Thanks for the feedback….

Hey Chris

Seems we have a similar problem. Cause I can’t mess with my old system ( to much going on there ), I uninstalled resolve 8.2 on systemdrive B (osx 10.7.3) and installed resolve 8.1.? . This gave me the same slow performance 6 nodes realtime instead of 18 ( i also had some memory/database problems with the memory banks (command 1/2/3etc) , but i didn’t look into that – probably an uninstall/install issue).

I have last fridays cuda driver on systemdrive B. And i would like to try to go back to an older driver version (4.0.50 preferably) , but i don’t know how (yet)

all the best

Hey Chris

Try to zap your pram (cmd.alt.P.R). To my surprise the realtime performance went up from 6 nodes to 11/12. This with system 10.7.3 and resolve 8.1 . I didn’t reinstall resolve 8.2 yet, (i’am not an install hobbyist)
It’s not as good as the 18 nodes i get with system 10.6.8 and resolve 8.1, but this could cover 90 percent of what i need. So it’s a step.

Why it works i don’t know, but i thought if Lion memorises all this windows positions it might as well do the same with power management. -but it’s a big ???, maybe it’s just luck-

are you saying that on 10.6.8 on the same machine you get 5-6 nodes more than on 10.7.3 ????

That is what I saw, yes. It was not a very scientific test, but anyway. I had like 5-6 more nodes playing back in realtime with 10.6.8 + resolve 8.1 than with 10.7.3 and Resolve 8.1. The only difference was that in the snow leopard version i had cuda 4.0.50 (from memory) and in the lion set up i had the latest cuda driver (well, last fridays).

I’am talking Resolve Lite, xdcam ex 1080p /25 fps macpro 4.1/2.26 gig /8 core/ nvidia gtx 120/470)

the strange thing was that i doubled the realtime playback nodes after zapping the pram -in the Lion setup-
though it came from only 6 nodes rt playback.

I have repeated the results a few times (4-8), but to draw solid conclusions i should do some more tests in some other configurations , – keying, bluring,sharpening whatever-

[Gabriele Turchi]

well…,
i thought you had a dual boot (lion and snow leopard and you were running the same project on both to obtain the results..)

that would be a precise test …otherwise if is based on memory not sharing the same exact footage and project nodes…who knows …

ps: about the PRAM : i read that help the render speed as well … i am wondering WHY the Pram gets filled up using resolve …maybe it’s something that the BMD team should have a look at it (or maybe is a OSX and Cuda usage issue ..)
