Serious lag in LP9/X in Yosemite

UPDATE!

Lag is still there BUT it's totally workable now.

I can work with this:) Happy enough.

Thanks for the update(s) ab!

Hi Andy, I tried you via your website but the email bounced!

re Logic Pro lagging in Yosemite.

I have an early Mac Pro with similar spec and just upgraded from Snow Leopard running Logic 9 to get Logic X and Complete Kontrol, which required a later OS (only Yosemite available now from Apple).

Logic X unuseable after a few plug-ins. Logic 9 slows down until I reboot.

Has your new graphics card really worked? Easy to install?

I can call you if it’s easier to speak…

Thanks!

Yep. My email has found its way on to an american junk mail list. I've taken it offline until I can figure out where thousands of "buy garage door" "shop at macy's" ads are coming from!! ahh modern life.

Yes, what I say is true. The £35 card has worked to a limited extent.

Previously the lag was over 10 seconds… completely unusable after a few tracks of 8Dio. No way I would have a client over in that state.

So. After the GT610 install.

There's still lag. But it's actually workable lag. It's just noticeable on NI plug ins.

The GT610 is also a cheap card, which took <5 mins to install in my old Mac Pro tower.
And even if it hadn't worked, £35 was a far better risk before even considering a new mac and days of re-loading samplebanks and plug ins!!

It's a 2009 Quad 2.6 with 16Gb Ram, 3x SSD's (samplebanks and system) and the GT610 so she's only just scraping by with Logic 9 on Yosemite but enough to get me through the next few films scores. Just remember to compress any video to an iphone size in quicktime to save vRam.

Thanks Andy. Before I take the plunge with that new graphics card, can I just check we have had the same lag issue on our early MacPro, please?

Mine is that since installing Yosemite, Logic Pro 9 (I gave up on Logic X first) slows down progressively over time, such that it gets slower at responding to qwerty keyboard commands and eventually unworkable. Increasingly I have to stop the music first to make any adjustment via mouse or command. The computer is struggling with the Logic programme, unlike in Snow Leopard which I could load endlessly. The only way to refresh speed in Logic is to quit and reopen, which I now do hourly. Is this the same symptom you had, and why would a new graphics card be the answer?

Thanks!

D. Yes we have the same issue.

After a while, if a session is playing, sometimes it takes over 10 seconds or far more to register a command. It's "unworkable". Volume, EQ, Transport all suffer a massive lag until it eventually takes a while to actually stop playing after pressing stop.

The cheap video card only relieved the problem but didn't completely solve it. It's now worklable and I can work on this system for a while longer.

I can now work for hours and with very little lag after a while but generally it's far, far better and even clients dont notice.

5 Instances of 8Dio/Kontakt however will tax it but i've not had to restart since installing the new card.

Summary:

My theory is that the 1.5 2gb video ram and faster processing on the newer card takes most of the heavy lifting from the CPU. That pesky Cpu#8 is now taxed less quickly.

Yosemite seems to be graphics heavy. A default GTX120 supplied in the 2008-09 macs will not do the job post-mavericks and should be thrown away.

It was a risk, but it was only a £30 risk, which, sure is food for a week but it's nothing in comparison to a new PC so it was a better call than saving for a new computer just yet. I had to upgrade because I depend on certain NI stuff.

Your other option is downgrading back one system, which might solve your problem.

I can't be of any other help, i'm afraid we're mainly on our own these days but this solution helped me in the meantime. I do still bounce down to stems not just to save processing and final mixdown but also to maintain performance when string arranging (heaviest plug ins I use).

Hi all / Andy

So I have fitted a Nividia Geforce GT 610 with 2 gb. First surprise is that there is no Mac Driver. The makers have told me that it is not Mac compatible, and that I should have bought a GTX 285 for Mac or a GTX 680 for Mac. Did you never run a driver, Andy? Both my screens are working fine, though I am still experiencing the same issues in Logic Pro of gradual slowdown and unresponsiveness, until I quit Logic and reopen.

I also notice that the Kontakt memory server v 1.4.2 in Yosemite no longer purges properly, even after quitting Logic, until I shut down my computer. Though I still have 20 gb spare RAM so that should be enough!

Something is gobbling processing power or memory until Logic grinds to a halt. Any ideas anyone?

Thanks

The Kontakt memory server should be disabled (not used) in all recent versions of osx. The OS handles all memory management. Disable then reboot the machine and try running Logic.

Hi Andy

I fitted a Nividia Geforce GT 610 with 2 gb. Is this what you fitted?

There is no Mac driver, the makers have told me that it is not Mac compatible, and that I should have bought a GTX 285 for Mac or a GTX 680 for Mac. Screens are working but Logic is still lagging like before, which they said could be down to it not being intended for a Mac.

What exactly is your graphics card spec, please?

Thanks
