Does anyone have Lurssen Mastering Console plugin + Windows 11? Strange things in Cakewalk after latest win update.

Hi everyone.

I've used this plugin on at least 3 dozen of projects without the issue I am experiencing now.  Last time (without issues) about 2 month ago. Before  24H2 update.  Yesterday, while I had a project  opened with this plugin, I've noticed that my mouse pointer got super slow.  About half slower than what it should be. It took me a while to find the culprit. First I disabled all plugins, pointer returned to normal. Then I deleted plugins one by one, until I reached Lurssen.  As soon as it was gone, life returned to normal. 

To re-test my find, I updated plugin to latest version,  re-launched Cakewalk. Opened a new blank project and inserted  Lurssen (VST3). Moused slowed down.  Lurssen has zero effect on mouse when opened in Reaper.   Nothing spiking in Task Manager. Plenty of resources. I've used plugin successfully on current machine for about a year. Only started acting up after Win update.  Also,  seems there is no delay inside the Cakewalk itself, but severely noticed if program is minimized and you just mouse around desktop. This pointer slowdown doesn't happen when using Reaper.

Simple steps to reproduce: Pre-requisite Win11 24H2

Open Cakewalk > Blank project

Load Lurssen (VST3)

Minimize Cakewalk > Move mouse pointer around Desktop. Lag usually kicks in in about 10-15 seconds.

 

Thanks.

I've not used this plugin before now to know how it behaved before the most recent Windows update. It doesn't appear to have any effect on my mouse pointer or UI reponsiveness in general, but it is a major CPU hog with an 8ms lookahead buffer that requires quadrupling my normal ASIO buffer to get smooth playback in even the simplest project that normally shows virtually no activity in the Perf Meter. The audio engine drops out immediately with a nasty glitch otherwise. Enabling Plugin Load Balancing also helps somewhat.

David,

Thank you for giving this a shot! I don't have a problem with audio at all or with mouse inside of Cakewalk.  Mouse slows when I minimize Cakewalk (no audio playing).  

Just one weird "brand new" side effect with this particular plugin.  Never seen this anomaly with any other plugins.  It feels like it is conflicting with some particular resources that mouse needs.  Who knows. Well,  good thing it's isolated.
