After updating to the build 1709 of W10, I feel that Opus has become less responsive. At least one other program also seems slower. Other programs are alright.
I wonder if it could be the new Exploit protection. I saw "5 system overrides" set for Opus. I deleted them and rebooted, but this did not help. (Maybe these were left-overs from when I tested EMET 5.5 once - unsure if they are enable by default.)
If anybody is experimenting something similar, post here and let's try to find the culprit.
Currently I'm trying Opus 12 and I feel it's work properly without any slow response / performance on my computer. Maybe some antivirus or other program which running the background cause this issues.
Changing the exploit protection settings did not work, so I am back at 12.6 and the issue seems to be gone. Not only that, but the other program also is back at being as responsive as it was.
Makes me think that the cause of the issue is the 12.7 version (not version 1709, as previously considered).
I had a problem with Opus and the latest Windows 10 build. At times it was like wading through treacle.
I eventually found that the problem was thumbnail generation. I use use thousands of thumbnails of all descriptions on my system. A bug in Windows 10 helpfully ditches them when the thumbnail cache is full - and the limit ir around 350 mbytes ( that's window's thumbnail cache not the Opus one). Sometimes all my eps and PDF thumbnails were re-building every couple of hours.
If you use many thumbnails that get stored in the Window's cache, it may be worth investigating.
Now I have fixed that problem I have to say that the latest Windows 10 and Opus worth crisply and with lightning speed.
But, there again, it could as Monty Python would say be "Something completely Different"
If you have a problem (or, as it sounds like, two problems) you're better off reporting them properly and letting us help you debug them. If you just give up and go back to an earlier version whatever the problem is will never be found and fixed, and you'll be stuck on the earlier version indefinitely.
I had a similar issue and it turned out that Windows would try to reinstall some driver repeatedly in the background. Around every other boot everything became sluggish and Start menu & taskbar were acting up. In the end I've resolved the issue by disabling the
