The lags do happen, and I've already been through support. The only way I got a definite improvement was a clean reinstall of windows 10. This gave a massive improvement from the problems I'd been having.
With that said, Objectdock DOES have issues with Windows 10. Lag does remain intermittently, also, if using Windows Explorer to preview your open folders, among the thumbnails generated of these, you'll get a blank thumbnail. Think this may have to do with some Windows apps but its there nonetheless. This is reproducible on every machine I've tried OD on running Windows 10.
The guys need to do a little more QA testing. They have have admitted there is an issue for some users but to date I still haven't seen any updates. Objectdock itself hasn't been updated with any new features in a long time and I think its understandable that some may wonder if things are on the slide at Stardock.
