Doom4 with Vulcan is kicking ass

[Deleted member 50521]

Just tested DOOM4 with Vulkan vs OpenGL. at 1440P my average FPS went from avg 75 to avg 160. This is insane. How can one API change bring so much performance gain? Anyway I feel very happy that my FuryX is kicking even harder now.

quite so for AMD indeed, not so much for us nvidia

Both the Fury X and the Nano have 4.096 ALUs and a bus width of 4.096 bit. That architecture is literally begging for async compute. The gains are certainly impressive! I wonder what Nvidia is planning to do since Asynchronous Compute and Asynchronous Shader Pipelines is AMD proprietary hardware IP...
Right now, all Nvidia can do, is emulate it on a software level. It'll be interesting to see if that software emulation will lead to higher FPS as soon as Nvidia supports "async compute" in Doom.

It's even more incredible how the Vulkan API handles CPU bottlenecks, though. PC Games Hardware tested an i7-5820K that they manually put to a lower power state @ 1.2GHz (in tandem with an overclocked Titan X @ 1500/4200). At a resolution of 1.280 x 720 w/o AA/AF this setup pulled 89 FPS running on OpenGL and 152 FPS (+71%) running on Vulkan

Got an nvidia card, as long as I'm getting a steady 60fps I'm a happy gamer

Rx480 is competing(or at least in the same range) with 1070GTX at this point.
Is the image quality of Vulcan worse/same/better than openGL?

As far as my eyes can tell I saw no difference. However everything is soooo smooth. The biggest change is the minimum FPS is constantly over 60 now.

This might move me to get a RX480 instead of the 1070 for my new build but I'm sure Nvidia will answer with driver "optimizations" so I'll wait some more.

That seems like a pretty bad idea, IMO. The GTX 1070 is massively faster than the RX480 in every single scenario so far, except this one. Even if DX12 boosts the RX480 it still won't be near the GTX1070. And the 1070 performs well in every game now.

Agreed with Frick. 1070 is 2 tiers above RX480 price wise and performance wise.

Also Vulkan is a general performance improvement even for nVidia cards.

Barely any performance gain, openGL sucks as an API hence why even the NV cards get a gain with Vulkan. The AMD cards are built for async so this will be a trend and it will continue to exist. Expect the next gen of NV cards to be power whores, just reading the writing on the wall.

You sure it isn't just that AMD sucks at OpenGL? Because they do. Have for a while (goes back to the ATI era).

 

[The Mac]

the hardware is fine, AMD just never bothered throwing any resources at the driver for OGL

so few games use it, it was pointless to waste the resources.

No one said they didn't. They do however have a $200 midrange video card with in 10% of the 1070 with Vulcan though.

Fair point. Have a thanks.

They certainly have the tech knowhow to implement it easily. I doubt any patent trouble will come since it's an open API standard and trying to stop them from implementing it would just be asking for trouble from courts.

Not to mention, NVIDIA has clever ways of getting around any AMD patents with their engineers, I am sure.

I wish every one on both camps shared the same view.
