OK after 12 months of trial and error to obtain an acceptable performance from an i7 laptop & external GPU enclosure hosting a 3060TI I gave up and purchased a new PC:-
Intel 9200K
32GB 3200 RAM
M.2 1TB drive
Gigabyte V690 Motherboard
MSI 3060TI GPU
Oculus Quest 2
In 2D with Nvidia Experience running I obtain 40-50 FPS with EVERY FS2020 2D setting maxed out
In VR using only the Oculus software and debug tool I now have a barely acceptable VR experience (eg need to focus in cockpit view to read Garmin display). No noticeable stuttering at 100 FS render scale with ASW off and Nvidia DSS on using either of the optimised resolutions.
I have avoided introducing additional SW as I do not understand the various layers with even the default SW layers (Oculus, Nvidia Experience/Control panel, OTT etc) let alone venture into OpenXR or NIS for example!
Where do I need to focus my tweaking, Oculus device settings, OTT, Nvidia (already set a FS Nvidia profile with various Web based suggested settings), FS VR ? Can anyone describe the various SW layers and dependencies? For example if I change the Quest device refresh rate/resolution, should I change the Nvidia DSS/FS resolutions etc?
Due to physical space constraints I am driving a 1080 display using HDMI.
