1440p AC origin HDR with the GTX 1080 Ti -2fps

This looks like a bench made to prove something in favor of AMD. Anyways , the fact is that GTX 1080 is not the flagship green team graphics card, but the RX Vega 64 is the red team flagship card. If we want to be objective then lets make a SDR/HDR tests of 1080 Ti vs RX Vega 64.
The point of this tests is just to make up that RX 64 is better card than 1080, which simply is not true at all IMO. Rega RX 64 has a 295W TDP, while 1080 has 180W TDP, which is 48.4 % difference and GTX 1080 still overclocks much more than RX Vega 64.
I would be very happy to see AMD beating Nvidia in TDP Power consumption, meaning much less power hungry and much higher performance graphic cards from AMD. More Efficiency from AMD is the name of game

I can confirm zero impact in performance on farcry 5 with HDR Vega 64
I think some how the fact Nvidia installs drivers in Limited colour has something to do with this result.
They hide something.and HDR reveals it.
Just a guess but maybe it has something to do with the fact Nvidia have to drop the chrome Info in HDR.
Not sure but its interesting.

Maybe nVidia's memory compression methods don't work very well with the bright pixels, so the 256 bit memory bus on that 1080 returns to what it actually is, i.e. $250 videocard material. Just beating around in the bush, of course...

Same settings, Nvidia HDR is 10 bit full range?

Vega64 is better than i remember.

I wonder if Vulcan will ever have HDR
Just keep in mind peeps.
If you buy a HDR screen avoid anything higher than 600 nits unless its a TV.
Honestly 600 nits is blinding from 2 feet away anything more is folly.

Maybe answer is easy :Vega 12.6TFLOPS vs gtx1080Ti -10.6TFLOPS ?

HH any chance you can run your own tests that are more reliable?
Last time i checked HDR should have little to no performance hit, it's just color reproduction right?

This is how i see things in my minds eye from my observations.
Do you disagree ?

EXACTLY!

Honestly, this is hardly front page news. At the very least Hilbert should update the post to reflect the oversite of Computerbase's testing methods.

I wonder is this is related to this problem ?

Much wiser and smarter people in here can answer that for me.
