Performance problems w/ DP 8, Win 10
Posted: Tue May 03, 2016 9:22 pm
Hello all, so recently I've been having performance problems in DP 8 when playing a very reasonable number of virtual instruments. This problem cropped up a few weeks ago, persisted for a few days, went away, came back for a few days, and vanished again this afternoon. I'm skeptical about how long this will last though so I'm hoping I can fix this for good somehow.
I haven't installed anything, software wise, since the problem arose. I did add more RAM to the PC after the problem first arose, but that doesn't seem to have helped.
The problem manifests itself as performance slowing down when the music gets very dense and a lot of virtual instruments are playing, to the point where the processing bar in DP is red, the interface is slow to respond, audible stutters, gaps, and then finally the warning dialog about performance pops up. During this time, the Windows Task Manager shows DP using 50% of the CPU. It's a 4-core CPU, so it seems to be maxing out 2 cores. When the problem isn't happening, the same place in the music will play back flawlessly, with the processing bar bouncing around around in the low green, and the Windows Task Manager showing DP using 30-40% of the CPU.
(I'm not sure how much I trust the Windows 10 Task Manager though.)
The problem can come and go without warning... it was stuttering like mad when I opened it earlier today, and when I came back this evening, it's working fine. I didn't even *restart* the computer during that time, just re-opened DP.
There are 3 virtual instruments: two instances of Kontakt 5 with about 20 instruments loaded between them, and one instance of EW Play, with just a few instruments loaded. There are no other plugins in use.
I've tried all kinds of things:
-Compacting the project, saving, re-saving, going back to versions saved before the problem arose, trashing preferences folder
-Turning on and off record for any or all tracks, trying to put the virtual instruments into and out of 'interactive' mode
-Using Windows Audio or ASIO as the hardware driver
-Turning off my MIDI keyboard
-Optimizing hard drives
-Adding RAM to the system
...nothing seems to help, it just comes and goes as it pleases. Has anyone experienced anything like this? Any ideas, before I nuke C: and re-install Windows? Thanks!
