The latest versions can actually approximate vRAM that is in use, it was added into the beta a while back and you had to fiddle around to enable it, but it's there in the latest betas right out of the box and you can just enable it on the OSD. I actually reached out to a lot of the mainstream reviewers back when this feature was added in and asked if they were going to change their stance on measuring vRAM requirements. Especially those reviewers who were taking 24GB 3090s and claiming that some games required 23GB of vRAM (which is obviously stupid and wrong). But it was mostly radio silence. Interestingly enough it was the lesser known hardware enthusiasts who were doing benchmarking of their own cards on places like youtube who were ahead of the curve and adopted a stance of measuring both.
it looks like this thread has more less gone full circle, in all of this arguing has anyone actually come up with a game that requires more vRAM than the 3080 has (10Gb) which doesn't already have a GPU bottleneck on the frame rate? My guess would be no, but just interested on peoples findings. I finally got around to playing RDR2, and in 4k on my 3080, maxed out it's using something like 6Gb.
i debunked the myth of allocation:

allocated vram shows as 7.7 gb and "dedicated usage" shows as 6.8 gb. yet vram related FPS drop happens anyways, and hugely. you would expect that with "real 6.8 gb" vram usage, game would not tank the performance. yet, it does
(7.7 gb is allocated for GODFALL alone, according to afterburner)
if it's really allocated in the terms of "empty vram", why does the vram spill to ram and tanks the performance?
there are something different going on here with this vram debacle. after this incident, i stopped trusting the dedicated vram value, because it had no meaning or whatsoever for this game
this game also debunks the myth that "gpu performance becomes bottleneck before vram is filled".
rtx 3070 can run this game at 1440p 50-60 fps ultra with ray tracing enabled. but once vram goes overboard, performance tanks to 30s. this is a huge performance deficit.
i tried lowering everything to medium and it still didn't help. it simply couldn't handle both 1440p and ray tracing in the same time

this benchmark is done by disabling everything in the background. no discord, no chrome. no extra vram consuming apps.
with discord enabled, even at 1080p you get frame drops.
i would like someone to test with a pretty normal pc config that have discord open in the background with 10-15 servers, geforce experience, and try running the godfall at 4k ultra with rt on. i bet it will experience same frame drops
