Question

VR horror quality since M-H-Link update.

hi,

on our HP laptop with a NVIDIA® RTX PRO™ 3000 Blackwell (12 GB) a twinmotion "presentation.exe"  ran 4 weeks ago with good quality.

now yesterday after some weeks of pause , there was in any way an update and a notification of "meta-horizon-link" that any driver update is needed.

now the same presentation file runs good ...as itself in its own UI..., but on the quest3 in VR mode it is initially loading veeeery sloooow and so  also running in very very bad quality. 

all the sides have black bars in VR and if you move they load so horribly slow. 

both times we had USB cable connection with the same cable and the same quest3 and as i said with the SAME twinmotion "presentation.exe"  file.  so nothing new belonging the hardware itself and the file we want to present in VR.

please help me what happened and what i can do to get that running good again.

...we need it next week for a exhibition...

many thanks!

    Check your Link settings in Oculus debug tool. You likely need to change either "Asynchronous Spacewarp" or "Sliced Encoding" or both.

      thanks steve, that did not really help, so i updated nvidia drivers at my workstation and had exactly the same problem as with the laptop. even with the hotfix 616-86.

      after reverting the driver at my workstation to 580.97, everything was good again.

      i will try to do this resetting of nvidia drivers also at the laptop when i get hands on it, cause it is a working laptop of a coworker. 

      so maybe we get it done for the next exhibition.
