Slow response of SFP 3.1c windows PC related?

zoofar · Post by **zoofar** » Mon May 12, 2003 3:10 am

Hi.
I have a PowerPulsar system with;
P3 650MHz
512 Mb SDRAM (100MHz)
PCI bus operating at 100MHz
MSI Motherboard w. VIA (yes, I know...)
GeForce3 (32Mb(?) ) Ti200 AGP (256 Mb aparture in BIOS)
Relatively new Western Digital HDD (-02) , don't know spec's.
A16 Ultra connected w. 2 Z-links
Windows XP pro. No service packs installed.
Direct X 9

My problem lies in slow windows response to operations in SFP 3.1c environment. My guess is that this is normal considering computer spec, but just to be shure...
When using 2448 Mixer and all 16 ins/outs of A16 Ultra, 1 MasterVerbClassic, 2 MasterVerbs, response of mixer faders( really everything editable in SFP) starts getting kind of slow. I don't mean deadish slow, just slow enough to be very annoying. Guessing maybe 50ms to as much as 300ms from click to response of faders.
Also when switching between window-sets, drawing of new window-set seems to indicate that SFP windows have been written in poorly composed Java-code (maybe they have...or maybe I should just by a new computer and s-up

).

Does this seem normal?
If so - any tips for optimizing?
Any thoughts on minimum reqs for PC (and/or MAC) to get rid of this "fader latency"?

some/many on planetz can tell you way better about this problem.
just my experience on my Mac: if I'm working on a heavy (Cubase) song, this 'knob latency' in SFP happens as well.
So there is PCI and or CPU involved I guess.

Hi Zoofar, welcome to Planet Z.
I had these problems running relatively small projects on a P3 500 and W98 a year or so ago. I had a cheap old graphics card(16 MB) and upgraded to Matrox 550. Then I upgraded to WinXP and followed a lot of the tweaks mentioned in the Tips and Tricks section of this Forum. My problems disappeared. The major tweaks that helped were the 'setting your memory usage to performance', 'getting rid of startup items','getting rid of messenger' and a clean install( groan

). But one thing that really helped was installing the Intel application accelerator which you can get from intel's website. Try these out and see what happens.

this behavior sounds about right.w/the via latency patch,and some tweaking things might improve a little.......a faster computer w/lots of memory and a good video card would be the best solution,of course...

Hello Zoofar,

What you are experiencing is pretty much the way it is.
Curiously the behaviour seems to change depending on which version of software you use. I've found, since SFP, the response is a lot slower and I'm on a P1.8gHz!
Whereas versions 2.04a - 3.01 were very responsive on the exact same computer (no delay when adjusting faders and knobs etc). Changing the video card to a Ti4200 didn't help either so I'm back on the g450.
It's an annoyance more than anything else. Maybe the next version will see some improvements.
However, as long as audio streams are not interrupted by graphic updates, I don't care too much!

WinXP is much better with the service pack 1 installed.
Just a little side note!
Cheers

SORRY, I didn't think the thing was getting through! Then I look and there's five of them.

i've experienced no slowdowns from sfp.

Hello!

The slowdowns I have experienced with the SFP have to do with the menus and not with the faders etc...
By the way, if you have a Matrox G550 graphics card, make sure that u have set the maximum colour bit depth on both screens. I have found that SFP is MUCH more responsive than running at a lower bit-depth.

bassdude · Post by **bassdude** » Fri May 16, 2003 6:07 pm

Well I'll be.... It was the bit depth. I changed it to 32Bit Tru Color and the whole thing is a lot zippier.

Originally in the earlier days, it was suggested to always select 16Bit colour depth. Maybe SFP was optimised for 32bit.

There is still a little bit of lag with the faders. But it is much better now. Thanks Rodos for mentioning that!

I'm definitely staying with the G450 now as it has 2 vga connectors which means no pokey DVI adapters. Much tidier.

Todays craphic cards are apparently designed to work at its best at maximum capacity, in this case 32 bit.
Don't ask me why or how but so i've heard.
Just thought i'd mention it to emphasize rhodos´tip.

saturday night's allright for carlsberg!
