The insane lag does not go away even when render has been paused. The CPU for luxcore is at 12%.

To update the topic.
Single default light group with path, lag gone, almost perfect 16-17 ms.
Single default light group with bidir, 4000 ms, still menus can be opened in LuxCore ui.

Path uses a single buffers (i.e. there are only eye paths) so there is nothing additional to do while BiDir uses two buffers, one for eye paths and one for light paths. So refreshing the screen with BiDir requires to merge the 2 buffers and, for very high resolutions, is an expansive operation.

The BiDirVMcpu doesn't play well with the refresh interval at all. Single light layer and the rest time is 0 with 7000 ms update.
