Title: Spark 1.7 uses much more CPU than before
Post by: anykeystudio on July 29, 2013, 10:17:06 am

I installed the new Spark 1.7 (LE) on my quad 2.8 intel with 4 GB ram and it uses up to 50% of CPU power alone. I haven't updated or installed anything else beside the Spark update. I am using Live 8.3. Now Spark is my most CPU hungry VST, beating previous champ the u-he Diva by far.

According to the 1.7 update log it says that I more economic on CPU, it turn out to be the opposite. Anyone else experienced this?

Nope, runs about the same with me. Intel i5-3210M, 2.5ghz, around 20 and 25% depending the kit/fx

I had one kit that uses almost 50%. Most kits uses 20% even if I am not playing any sounds. This was lower before (1.6.1), where spark wasn't noticeable in that way.

Other observations about the CPU consumption in 1.7 ?

Hi there,

could you guys provide a bit more detail about the operating conditions when these high consumptions occurred? Were you in standalone or plugin mode, which kit were you using, etc.

Cheers,

Toby

Oh and of course, your OS

Hi, I am using Win 7 64bit (SP1). And I am running SparkLE in Live 8.3. Version 1.6.1 of  Spark only used about 5-8 % of CPU, but now its constant at 20%, even when not playing any other instrument and samples from Spark. Some kit, with long samples consumes even more, up to 50%. I will find out which kit this was later.

PS. Will also add my Desktop specs.

Chers.

Here what I found when doing some more testing of Spark 1.7 in Live 8.4.1 32 bit. The CPU load is read from the Windows task manager. This is only a indication and no thoroughly test.

• Clean project with only Spark not playing any sound, consumes around 5-10% CPU
• Playing a kit (Electro Shock) with has automations, consumes around 10-20% CPU
• Inactivate the Spark Vst, the CPU load drops to 1-8%. Only Live with no effect or instrument

The new kit/Instrument browser is slow to open, it takes 5-8 sec after I pressed Select-Kit before the browser opens.

Intel Q9550 Processor, 4 Gb Ram, Intel SSD Drive, Windows 7 Ultimate 64 bit.

Hi anykeystudio,

I will relay the CPU information to my colleague who looked into the issue for v1.7
You said that you were pressing select + kit to get the browser to open; you don't need to press select, just the kit button. I don't think that will speed things up but I just wanted to let you know!
Do you have a large number of user projects? That may be why the browser is slow to appear.

No, only the default projects/kits/inst. in 1.7.
