What FL version you are using?
Your CPU are intel or AMD?
Windows XP, Vista or 7?
10.0.9
Intel
Win 7 64-bit thru OSX Mountain Lion bootcamp

Uh oh, bootcamp rings a "ding ding ding" button. It's rarely supported as well.

Supported by....certain soundcards, or..? I've heard of quite a few producers using Bootcamp for FL.

Bootcamp is (afaik) just a boot manager. Once you boot into Windows, it's Windows. Running FLStudio, Vegas, Camtasia, all kinds of Win stuff on my MacBook. Actually runs better there than on my Dell laptop.

Even have a VSL 22 and driver instaled on it, whose drivers operate (for the dsp) at the kernel level or something. Works fine.

No, by support iirc bootcamp isn't supported by FL. Could be wrong. Certainly not suggesting that bootcamp can't run things. Anyways, I'm just confusing people so I'll bow out.

Hey Hibidy, I wasn't disagreeing with your comment re: support. I was only saying that booting into Windows there is no different than running Windows on a Win machine, on an Intel mac.

I rarely even boot my MacBook into OSX anymore, mostly because some of the Mac software I own (like Studio One) won't even launch on the version of OSX it has and I have no desire to upgrade OSX on it.

Thanks H.

I know in Ableton Live if one CPU core is at 90% and the other three are at 20% then the CPU meter in Live is shown as 90%. Live tries to run each track on it's own core or virtual core. Maybe FL is the same.

Bought a Focusrite 2i2 soundcard.
Reinstalled FL Studio.
Ran DPC latency checker, at about 500u - 1000u.
Ran Apple Hardware Check, came back fine.

Still same problem.

If I press one key from an init Massive patch, I get about 25% CPU. Nexus goes up to 99% if I press a triad in quarter note lengths. I have tried everything. Please help if you can. Thank you.

500u - 1000u seconds is bad news. Unplayably bad news. A good i7 Win7 DAW, should have DPC latency values under 100us and rarely over 150us.

Something is either:

a) wacked with you Win install on boot camp.
or
b) you have a bad mac (sick mac?)
or
c) horrible luck

To eliminate a variable, have you booted into OSX and installed the 2i2 and tested it with another DAW? If you still have horrible CPU usage and audio dropouts it would point to a hardware issue. If not, it would point to a bootcamp/Winuhs issue.

Have you tried turning off non-essential devices when in Winders to see if something is hogging the bus? Turn off WiFi, for example.

What is the buffer size you've set in FL? What happens if you use a really large buffer? What happens when you triple buffer? Have you tried using a fixed buffer size from the processing panel for each instrument? If so, what happens.

My guess is either a hosed driver or bad buss mojo (and not in a good way).

You gotta get the DPC latency under 500 at the very worst. 250 really. Sure seems like a driver/bus issue, which is no fun to hunt down.

Happy troubleshooting. Or at least bearable troubleshooting. And don't pull your hair out. You might need it later.

Shot in the dark. Does the mac have a bios? (can't remember) I just wonder if maybe speed stepping or similar is doing something.

I also thing you should try reaper (because the demo is uncrippled) and see what happens, but I'm with mandolarian, that is way too high.

I just noticed this, "max" isn't any better than too low. I can't read the whole thread but you have tried several buffer sizes, right? Try 512 for stars and see if there is any change.

Thanks for your replies.

Reaper gives me about 200u.

For the Focusrite USB 2.0 Audio Driver, I can only go up to 10ms in the buffer screen when I press "Show ASIO panel." Equals out to 442smp.

tried disabling wifi.

tried triple buffer.

fixed size buffers is selected by default, didn't change anything.

no idea about the bios thing. :/

So...the 200us DPC Latency in Reaper, was it in OSX or Windows?

Windows. Tried Ableton in OSX with the Focusrite and everything was fine as well.
