Some captures:
1440P benchmarks comparing GFN and Native Desktop
4K Benchmarks (only available on Nvidia Shield)
Latency tested on 60 and 120 hz (120 only supported on Crucible):
Outriders comparison at 60 hz:
There are quality comparison for outriders but I can't upload the pictures. Basically native looks best, followed by GFN and then the rest.
Finally pricing for the 3080 tier (which by the way is an A10G which could have some impact on game performance (less memory bandwidth but higher everything else):
Not bad but a bit too expensive for my market.
