  • Maya 2019 slow with vrscenes and Cached Playback

    Hi,
    it seems I found a bug with Maya 2019, V-Ray and V-Ray scenes.
    The higher the vrscene polycount, the more unresponsive Maya becomes. Maya noticeably hangs before any interaction is possible. With 10.000.000 polys, Maya takes several seconds before I am able to navigate in the viewport. Once the viewport responds, the FPS is very high (around 65).
    Maya is constantly utilizing 1 core at 100% (5% total).
    If I turn of "Cached Playback", Maya responds quickly again.
    If I set the "Cached Playback" "Preferred mode" from the default "Evaluation Cache" to "Viewport Hardware Cache", Maya responds fast as well.

    Maya 2019.2
    V-Ray 4.12.01
    Nvidia Geforce 1080ti
