  • I can see the potential. There are a few things that would possibly make me not use it over FS. That would be the camera movements. Im weird and i use that little circle and arrow thing a lot and it's just in too big of a window and im kinda stuck to what fs offers there. Also, there isn't a favorites available in toolbar. I realize this is an alpha and things will change. Also, the chat window doesn't have groups and friends available to select form there. That is what I have seen so far. Pretty laggy at the moment. Not sure if that is because it is still downloading textures or not. I am on AMD. This review was less about performance atm, but more over QoL. Thanks :)

    All in good time :) stabilising the render is priority number 1 over any features I decide to 'borrow' from other TPV's
  • Last update was stuck on compiling shader: screen space reflection post, for all eternity new updates stuck on brdf gen shader

    thanks for the heads up , will look into this. But bear im mind this is pre alpha, for bugs drop me a line in the GIT or forums :)
  • Testing Build S24 3535 on Win 11 with a Laptop GPU Nvidia 5080 RTX, 32gb ram Intel i9 275hx. Great performance, 120fps on quiet sim, 40 plus fps in club with 40 avatars with high settings, everything on, mirrors on realtime and ultra settings. Shadows on high sun and lights. No extra tweaks tested yet, just the basic viewer settings but Good, only thing I don't like and never have is the HUGE camera controls :P (I like to have cam control on screen all the time but can't but hey ho, just my personal preference) Nice to see viewer still being worked on x

    Nice Rig! And that GPU is right in the sweetspot! Thanks for the kind words :)
  • Best viewer on the grid IMO. Fast renderer, high FPS, fantastic for filmmaking and just a lovely looking SL viewer. I used to hate any viewer from v2.0 onwards but have come to enjoy using this now Kirsten has been working hard with this viewer. Usually ahead of the curve while having features that the Official viewer does not have. Cant remember the last time it crashed on me, just a solid build that handles the most intensive spots on the grid, even when 90+ avatars are around me. Thank you for all your time and energy put into this, it is really appreciated! Specs > AMD RYZEN 7800X3D | AMD 9070 | 32GB RAM | 990 PRO M.2 This viewer also runs on my RYZEN 4300G | 16GB DDR4 system which does not even have a dedicated GPU installed in it :D Cheers Buddy!
