After Upgrade To RTX 2080

Reminder: If you encounter any issues with Enscape (including installation problems) or your subscription please reach out to our dedicated support team directly through the Help Center or by using the Support button as detailed here. Thank you for your understanding.
  • Hi,


    1) i just purchase new RTX 2080 super, i already enable rtx raytracing in settings.

    but why when i change or move object in sketchup, the real time updating in enscape is really slow ?

    more slower than my previous graphic card (gtx 1060)


    2) Why reflection still not great for RTX ? (picture attached)


    my specs amd ryzen 7 2700

    RAM 32GB

    VGA RTX 2080 super


    i'm using enscape preview version 2.8.0-preview.5+23599

    thanks.

    Hey,


    regarding 1) real-time update speed shouldn't be related to RTX. How fast we get the updated geometry from Sketchup depends mostly on SU itself and is computed on the CPU so a different graphics card shouldn't affect that.


    2) Based on the images the reflections do look fine to me? Most of the geometry is visible. Please bear in mind that trees may have a really high polygon count and may therefore not be selected (even with RTX), especially if there're further away. One more noticeable difference in the reflection is that the ground material doesn't match I suppose. This is most likely because what you're looking at are the backsides of the environment mesh's faces. Only the material of the front face is visible in off-screen reflections. That's a general limitation (not related to RTX specifically). Easy to fix though: Either swap fron/back face or make sure the same material is applied to both :thumbup:

    1) my SU is no loading when i move objects, this is not big project that have a lot of geometry, but enscape loading slow when i move object in sketchup since i change to RTX, but before i use RTX that is fine, (when using GTX 1060) really fast real time updating in enscape.


    2) Okay, got it
