That Renoise and all my VSTi plugins work fine on a 64-bit CPU with 32-bit emulation. 
I’m running an Athlon FX-53 overclocked to 2.52GHz and playing a song the CPU usage is usually under 10%. 
so you say you’re running a CPU being worth around 820EUR? - ok, you should really get something for your money, but i don’t think the actual performance you get justifies the high price.
and oh, you’re playing the wrong songs apparently 
but grats on your new rig, should be fun nonetheless.
No, I didn’t buy that just for Renoise. 
I’m also a big gamer, I run SETI and I start a 2-year programming course in college in September so I thought it would be good to have a 64-bit CPU ready for XP-64 & Longhorn.
It’s a lot of money but I don’t plan on upgrading again for a long, long time.
I’ll go for one of those pretty soon m8! 
So, is THIS the side effect that 64 bit has on Renoise?
Drastically lowering cpu usage?
Sounds SO sweet
sorry, I had to LOL at this 
a faster CPU won’t turn you into a better coder. The viceversa is quite true 
richard, would you mind me sending you some kind of a “test-tune” for benchmarking purposes?
would be quite interesting (at least for me) to see how your little sucker compares to my P4 3,5Ghz in terms of CPU load with a specific tune.
so if you got the time, please let me know so i can send you that sample
what’s the purpose of getting such an expensive CPU as it will be cheaper when you’ll get your hands on XP-64 ?
i’d like to know how it would react to my renoise tunes though 
i read on the register the other day that Athlon64 prices are down up 30% this week. i’m all over a 64-bit cpu… as soon as i buy a new car… 
allright, will do so tomorrow
Looking forward to it, be warned though - I’ve come above P4s overclocked to 4.2GHz in benchmarks so far. 
hehe, you sure will smoke my 2.8@3.5 P4 HT, would be a shame if your 700EUR+ CPU wouldn’t do so with my 180EUR counterpart.
all i wanna know is to what extend it will perform better, so here we go 
>> download test tune << [755kb / RAR]
everybody else interested in comparing, post your CPU load with this tune and your system specs here.
cpu load: jumping between 80.8 - 81.2%
system: P4 2.8@3.5Ghz, 250mhz FSB, 1024MB PC500 DDR 1:1, Radeon9700pro, P4C800-E DLX
I did a quick test now and there are some factors you can control for changing the results. For example:
With discop shown:
Processing buffer size 1024: 60%
Processing buffer size 128: 70%
With track scopes shown:
Processing buffer size 1024: 62%
Processing buffer size 128: 72%
Also the window size has a certain effect. And then I guess ASIO contra DX is a difference. And then the big factor: samplerate.
@11k I have 17%
@48k I have 77%
@96k I cannot even play the song
I’m wonder where problem is, keith.
On my Athlon 2500+ it runs without lacks at 22 khz.
@johan
ouch, yes you’re right.
forgot about all these factors.
so my values rely on the following settings:
track scopes = shown
pattern follow = enabled
samplerate = 48khz
processingbuffersize = 512
device type = ASIO (powered by “ASIO4ALL driver”)
latency = 15ms
window size = fullscreen (1024x768)
soundcard = soundmax integrated audio (onboard) using s/pdif coax-out.
CPU Load measured by renoise in the upper right corner = 80.8-81.2%
what’s your system spec, johan?
pump it up for 48khz. hehe 
Pretty insane test tune. On my Athlon 2400+ it uses 100% and sounds like my hat if it was high 
<-- imagine fitting a hat on this dude and you know what i mean.
Latency: 11ms
Frequency: 44khz
Buffer: 512
Soundcard: Terratec EWX 24/96
PC: P4 3ghz FSB800 with 1024MB RAM, Windows XP
Scree: 102476816b, both windowed and fullscreen
Max CPU Load: 92%
Plays almost flawlessy
(sucking soundcard I got)
Just to clarify: You use 10024x768x16 in fullscreen? That’s why I did now. Soo… here goes…
75%
on an Athlon 64bit 3400+ (2200MHz)
1.5Gb RAM
SCSI drives
Sound blaster AudioPCI (some old crappy card)
DirectX @ any latency (doesn’t affect CPU for me)
Win 2000
I’m at work now so I don’t know FSB and RAM type. And I have no possibility to try ASIO. I’m not sure I even dare to try this at home…
The value is taken from Renoise’ CPU meter, not from the task manager.
