So I have a problem with CPU usage on my Macbook Pro. Starting WL7 in 32-bit mode, no files open and no plugins, uses about 13% CPU, which I think is fine.
Starting WL7 in 64-bit mode, same as above, CPU is about 35%. With a file open, no plugins, CPU usage creeps swiftly up to 80% and stays there. Really annoying, as the fan then spins up to keep the machine cool.
I’m using the internal audio only, and buffer size is 1024 samples (the buffer size seems to make no difference at all).
Any ideas what’s going on, or anything I might be able to check? I already cleared the preferences and restarted.
I have Cubase 6.5 on the same machine. It runs with exactly the same processor load whether I’m running in 32 or 64 bit.
My specs are Wavelab 7.2.1 (build 600). Macbook Pro is a late 2011 15", OSX Lion 10.7.4, 2.5 GHz Intel Core i7, 16 GB RAM.
‘About Wavelab’ says “Session optimized for CPU: Unknown CPU (y8)” when running in 32 or 64 bit modes.
Thanks in advance,
