Doom Vulkan vs Open GL performance

Though I was getting 90fps at 3440x1440 using ultra/custom settings it didn't seem as smooth as before.

Just realised I left V-sync on in the game settings from my previous play though and I bought the X34a monitor with G-Sync so V-sync should be off. Will try again tonight.

Should note that I may be cpu limited i5 750 at 3.6 GHz, 1080p.

At the end of the level when the gate to hell is opened I got (mix of high/ultra);

openGL
Standing looking at the area before starting the event 70 fps
fighting around the gate thing 45-70 fps

Vulkan
Standing looking at the area before starting the event 92 fps
fighting around the gate thing 70-90 fps

In the following level when you go to hell I assume (ultra), in the first cave with no fighting

openGL 75-80
vulkan 97-105

I do wonder if some of my gain ius due to this;
http://www.dsogaming.com/news/doom-benefits-greatly-vulkan-vulkan-versus-opengl-performance-comparison/

"Not only that, but the game is now able to “properly” scale on multiple CPU cores. Below you can see the CPU scaling of our Intel i7 4930K on both OpenGL 4.5 and Vulkan. As you can see, Vulkan was able to take advantage of all of our six CPU cores. On the other hand, and while the game scaled on our hexa-core under OpenGL 4.5, it relied mostly on a single CPU core."

No stuttering here at all with Vulkan. Now uploading a vid to show performance and very very impressed. Nightmare settings at 1440P and the game flies along. Not a single gripe in the short time I have played it.

on 1080p my performance improved around 20% and on 1440p it is 15%. I did not try 4k yet.

Really Nvidia has not forgotten Maxwell yet.
 
Here is my recording of Vulkan. Got to love ShadowPlay - Just hit record and off it went, no fuss or bother. Super silky smooth as well and all maxed out :)


Will need to finish encoding and will switch to 1440P (eventually) but I need sleep from working all night :)

Thanks for the heads up, will give it a go when I get back from me hols.

Doom's still on GMG for ~£19 for those looking not to get ripped off in the mm.:p



:eek:
That's about the same price as a 1080p G-Sync panel alone never mind a £230 gpu too!!!

More importantly, is FreeSync Vulkan ready?

not a ripoff, the game is worth it's price, ppl should buy it from steam or their official website, PC gamers need to learn to support what's good for them, when a good vulkan game pops buy it, and dont go cheapo on it with shady sites to save few bucks :D.
freesync have nothing to do with API, it's just between the monitor and the gpu.

For some reason my overclock wasn't working in Doom so the results are stock.

1080P Ultra setting :

Opengl = 47fps average

Vulkan = 80 fps

I can't seem to capture a screenshot in steam but the performance is amazing with vulkan.
Fantastic result!

Wow, anyone who gets such disastrous performance in a game as well optimised as this to begin with at 1080p should probably think about upgrading, regardless of one title with belated support.

It's interesting why some people are having gains, while some people ain't, even when using same gpu's. I quess there are some settings that are bugged. Still it's good to see proper Vulkan support.

we are back to CPU utilization era with Mantle :D, performance gain will differ depanding on the level of bottleneck your CPU has, and the gain would also vary depanding on the IPC and core count.

I actually had a 290X but sold it before the launch of the 480. The 7950 is my old backup card. I will be upgrading soon when all the recent new cards have landed. If AMD announce something else then maybe I'll wait longer.

The 7950 OC is actually pretty good in most games when overclocked.
 
I managed to capture some gameplay using Borderless windowed mode and Mirillis Action. Recording performance cost is exactly 15FPS using this method. :)

5960x @4Ghz
1x Core Pro Duo @1172/545Mhz (CrossFire is not working)
Crimson 16.7.2
Vulkan API
1440P 60HZ @ Ultra Settings + TSAA x8 with Async Shaders

Get that cpu clocked up there I had mine running at 4.2ghz without any problems :p you should with a bit of tweaking be able to hit 4.0ghz it was a fantastic cpu!! and tbh if it is clocked up there it'll still do a good job today! :)
