Doom Vulkan vs Open GL performance

Right, noob error amended and apologies for that guys. Here is the updated vid and I did get the timings a little better this time as well, so not all bad.

Vulkan is performing worst here. Vulkan is either around the same FPS or 10fps slower apart from the beginning OpenGL is around 20fps faster.
Nvidia have work to do.

Nobody seems to talk about it but Fury X currently is killing both 1080 and 1070 in this game. The biggest gains are actually with Fury X 60 percent or smthng lol

One of the tests shown so far at 1440p with the Fury X. Looks amazing, now the TFLOP value of the card actually seems to mean something.

Woah. GoGo Gadget Boosters!!! Forgot to unpause my download last night though.

Looks like it runs better in some places and not so good in others. Strange result.

What are you guys using to capture the full screen footage? I can only capture window mode with Action. Even borderless is not working.
 
Finally got a chance to try this. Getting quite the increase.
At 4k using vsr at the end of the monorail ride in the UAC I was getting 37fps before and now 52fps. Most of the stages I've tried so far are holding steady over 60fps at 4k where they would be low/mid 40s average before.
1440p is getting similar fps in Vulkan to what 1080p was giving in OpenGL.
 
The biggest issue for AMD is not being able to run with max settings on most of their GPUs due to the VRAM limitation. They have the performance figures nicely but you need 5GB+ to run the Nightmare settings. A 390/X or a 8GB RX 480 is the only cards that I know of (and a few 8GB 290Xs I believe).

A real shame that in truth, as they could cope with frames at 1440P and max settings on a Fury X/Fury/Nano but needing to lower settings to remain under the VRAM cap.
 
Here is my theory regarding amd performance in dx12 and vulkan.

There is a video also on pcper youtube channel with the amd chief designer in it which also has contributed to my theory, in that video he admits amd focused on the console in previous years and sort of let the pc side of their business fail, but they are now starting to focus on pc again hence their recent improvements both on the drivers and hardware.

So my theory is things like async compute have been used on both console platforms already for several years, this would explain why amd cards even the old one's support it well already and why developers were able to quickly implement async compute into their games. This also goes a way into explaining why pc games have suffered in performance vs consoles for several years as well when used on comparable hardware, sometimes even when on much superior hardware.

My nvidia theory given how they cutthroat in making money is they already can make it work but are not implementing it until they need to for maximised profits, they will probably have it working on some new generation card when there is enough games on the new api's to influence sales. Sort of like how gsync supposedly needs a hardware module yet they managed to get it working in laptops without one.

I can understand that. But it is no way near anything like that for me as I am happy to play with Vsync on in most games :p

I tell you one thing I noticed about Doom which really impressed me with the developers. I do not have vsync on and have not seen a single tear in that game and I played it mostly getting low 30's fps. How are they managing that I wonder?

Being opengl it probably supports triplebuffering

Nobody cares how much a Fury gains, what matters is how a card performs and so far I have seen nothing from AMD that comes remotely close to a 1080. Also, good - ish performance in one game does not a card make and certainly does not warrant the "killing" you're talking about. There's a long way to go there, let's not put the horses before the carriage, shall we?

Thanks =) Here is Fury X gameplay with vulkan, hope for crossfire support later so 4k can run higher fps.
Around 15-17fps lower with that recorder like you said. My Fury X got new life in doom now.
Only have a OC 4770K so maybe a newer cpu get some extra fps. Need to convert the video in windows movie maker before youtube would take it.

110-130fps

Nice video. I recommend using handbrake to convert the video as it's quick and easy and with the right settings trims the file size down nicely while still remaining high quality.
