i have installed renoise at windows 7 as well with ubuntu studio 11.10 and 12.04…
when i playback the demo track (beatslughter something) in windows my cpu stays under 20 % but in linux, no matter wich version i use the cpu goes up to 50 %
how does it comes? are there any tweaks in linux to optimise, like disabling background services and so on?
Funny thing tough i only experience this diffrents in cpu usage with an AMD CPU (E-450) wich has the internal Radeon HD Chip, with an Intel i3 Core the CPU usage is in linux and windows the same…
Under Windows the Renoise CPU indicator shows about 20 %, but the CPU indicator of W7 itself (ctrl+alt+del / taskmanager) shows only 5 % CPU but sometimes when somethoing mayor happens inside the track it goes shortly up to 40 % then back to 5 to 10 %… Even when the CPU indicator of W7 shows 40 % renoise shows 20%
In Linux, the CPU graph as well as the CPU indicator inside of Renoise show constant about 40 to 60 %
Overall it seems that under Windows 7 you get better CPU ussage? I am using Ubuntu Studio 12.04… this behaivor as mentioned is only with the AMD CPU Laptop…
I have tried about 10 diffrent PC`s with about 5 diffrent Audio Interface each since Suse 11 / Ubuntu Studio 9 I am well impressed how much especially ubuntu has developed… and i used to have a webserver with Suse which was running well…
But i am realy tired of always dongle around about 2 weeks to 2 month for every single bit, which is just a mousecllick in windows. Also the so called low latencies of linux are more a dream and far far away from realaty… Linux eats up much more Cpu and latencies are anyway at abou 70 ms and still get Xruns, cracks and Pops in Sound…
I am tired of the Windows Logo but Linux is far away from beeing a good, fast an stable solution for professional audio production, even if renoise works very well on linux…
i dont even blame the linux programmer guys… because i see, the problem is the lack of support from the hardware manufactors, there is a huge lack of support for good and fast device drivers… firewire / ffado works quit well, and if you have an intel machine with nvidia grafik you might could give linux a try… but for me… i do need a running machine, i can sit on and make sound, no machine i boot up and nothing works, well linux works… but with always xruns, which means you get cracks and plops in sound if you are using an external audio interface
Linux runs so bad on an AMD with ATi Graphics… sliders and faders within renoise are lagging when you move them, its a shame, as mentioned, on intel works much smother… so do i need to buy another new pc now? i dont think so… i use windows, gives me less headak
