Where's the 64bit sticky thread? Right here, that's where

caleb82,

Kudos for doing such a test! It would have been better to use several instances of the plugin, and then replicate with several DIFFERENT plugins, but then this is really just verifying what one would expect, anyway.

Shocking to see the percentage difference. That's higher than I expected.

Now here's a thought:

What if you are running 30-40 32-bit plugins? Does the total cpu usage go up by that same percentage? You imply this, but we don't know this. Perhaps there is a chunck of cpu-power allocated for the "bridging" mechnism itself, and then all additional plugins give a very low additional hit. I doubt it, but it's possible.

One has to be very careful as to what conclusions are drawn from minimal data.
--------

What I'm dying to see is a similar test but of XP32 vs Win7-64.

Yup, and thanks for the reply.

I thought of exactly that point myself, and if noone else does it before me, I'm going to do just that. Maybe tomorrow, maybe it'll take one or two days, have to wait and see if time works for or against me.

just about to try windows 7 64 bit and was wondering...

... if you run reaper 32bit in win7 64 with over 4 gig of ram, is reaper allowed to use the same amount it can with the 3 gig switch being that it is "LMA aware"?

I know it is limited still but is it limited to 2 gig or about 2.7 / 3.2?

thanks

found this:

Each 32-bit program is assigned a 4 GB virtual
memory address space in the WOW64 subsystem - with no requirement for the OS
which is still running in the 8 TB of virtual memory address space it gets.
So, if your 32-bit program is written to take advantage of >2GB of memory
(using the LARGEMEMORYADDRESSAWARE compiler switch), it will automatically
see a full 4GB.

Happy dance!

Thanks for that! If that works then thats good enough for me as i can use 32bit reaper and my 32bit plugs and squeeze out 4 gig. I hope this is the case? Anyone actually tried it though?

Thanks much! I was a little confused before this thread, but now I have a great mp3.
