anyone have no slow down on pulsar graphic when dsp is mostly utilized?
and CPU still at 6~10%

I'm using an old ATI Rage 128, and Pulsar graphics are very slow when I'm running all my DSP's (7) and Cubase/Battery. (on a P3 1Ghz, 256 MB RAM)
It makes switching between mixer views and synths a pain. It's probably the most annoying thing about Pulsar!
So yes if people don't ahve this problem, please tell me which videocard should I get?

thats a bit weird... I get a slowdown on high-cpu (this is normal), but not with full DSP's.. I've tried using a Matrox G400 and a Supergrace GeForce2 MX400 64mb. Both behave very similarly.

Word has it that the new 3.1 software has a slicker GUI. But in any case high DSP usage should not be causing a graphical slowdown, going by my experience anyway (I've set up several Pulsar systems for people).

peace

Well, maybe it's jsut because heavy DSP usage usually goes hand in hand with lots of different devices on screen so that may be slowing the interface down, rather than the DSP usage.

The only time I notice a slow down with the system or the graphics is when I am using a lot of PCI intensive things... full sampler, a few reverbs, a bunch of delays. This pushes the PCI bus.

Usually in normal projects, I don't experience this.

Remember unlike other solutions, this stuff happens with ZERO LATENCY and therefore puts a larger strain on your system's bus, which can effect the graphic card's ability to redraw the screen. Try using some outboard gear to take some of the PCI traffic, or pray for a generation 3 board with onboard ram that can be added to your current system. :wink:

I have the same Ati card, and have no problems at all. The graphics are really fast, no matter what synths I have running.

What colour depth/resolution are you running Dxl? That could be the cause of the slowness.

I've been wondering about this too.
Do you think it would be technically possible for, say, Pulsar II to make use of RAM on a future expansion card connected via sync plate?

i have a geforce card.ran the dsp meter to the end last night (12 dsp's) lots o plugs in logic, 27 tracks,no slowdown.

The fact that the UI is sluggish has nothing to do with PCI traffic when you have an AGP card. The AGP bus, altough part of the PCI PNP enumeration, is wired directly to the north bridge, and doesn't affect the transfers on the PCI bus (south bridge), so, sorry to be blunt, but that's total BS.

I think the sluggish UI is just BAD programming, and tons of wrappers, plain and simple. I would trade anytime a bunch of 'fla flas' for speed. As for zero latency, nothing to do with it also. I have an OASYS PCI board, the UI is *VERY* fast, the audio meters are extremely responsive too...

I also have a Korg Oasys and sure the UI is faster but its also plain, boring and ugly. I much prefer the look of the Pulsar stuff, to each their own.

About AGP cards not being effected because they don't share the PCI bus: well obviously the AGP uses the AGP bus connected to the MCH & the PCI bus is connected to the ICH2 hub. Try it yourself: load 10 masterVerbs and watch the graphics slow down, compared, to say, 2 masterVerbs. There is a correlation and that is all I am trying to say. Remember the Oasys can only use it's onboard memory: makes it better behaved, but also a limitation. Just as CW uses main memory and is therefore ("only") limited by the PCI bus.

About poorly coded graphics library: so you're a coding guru that got a peak at the code, huh? But really: i don't think it's poorly coded, but simply not using hardware acceleration. Have you coded alpha-blending before that was cross-platform and anywhere near as fast as the Creamware GUI without using hardware-specific acceleration? :smile: I have and it's quite tricky.

None of this is to say I wouldn't mind it being faster. I would like it faster. But it's far from too slow (on my machines at least) and definitely usable. I don't sit around all day dragging devices around screen timing them. I load the devices, assign midi controllers, and use them.

mmm... it seems my drivers were just a bit out of date. I updated them and now it's better. Damn drivers!

ok i get the conclusion
they optimized for Matrox from V1~v2
but they add optimizitation for Gforce in V3
but i do experience faster graphic tho
please optimize for more.

i have slow down graphic when useing more DSP
i have KyroII for my video card
which it's performance is almost about the same as Gforce2Pro.

geforce2 mx something....i don't really care about the video card.i just got a fast one w/ 32mb o.b.
