I’ve had some real problems running C7 having had a really good experience with C6.5 with the same hardware and same setup. I can only get a reasonably stable project with latency of 12ms+ - this is reported in VST setup as 24/36ms (presumably this is the overall round trip latency) but the CPU bar is still hovering around 30 - 50% with occasional spikes and stutters if I do something rash like resize a window or scroll across. Even with the highest possible buffer settings, the CPU meter is still 20 - 30% and moving around.
I can’t use Ozone 5 anymore, which is my favourite mastering plugin as this completely screws the performance, regardless of buffer settings.
Interestingly, a few weeks ago I reinstalled Windows 8 (previously it was over a Win 7 installation) but this may well have left the old prefs behind from C6 / C6.5 somewhere. ‘Refresh Windows without affecting your files’ seemed like such a helpful feature until I realised (afterwards!) that this meant that every single non-Windows piece of software would be removed. AAAAAAARGH!!! Even this (unintentionally) radical action didn’t improve things, but at least I got rid of some of the more irritating Sony software.
What do I need to get rid of to wipe out these old prefs in case these are causing the issue? I’ve tried disabling Wi-Fi and/or Bluetooth, rolled graphics drivers backwards and forwards, played with swapfile settings, graphics settings, power profiles (all settings max performance), C3/C6 in and out of the Bios and all sorts of stuff but nothing seems to improve performance. It’s driving me nuts!
If someone could give me a clue on eliminating old prefs or any other ideas, I’d be really grateful. C7 is such a cracking version but this is really frustrating - surely it should work pretty well on my hardware?
