Tested the opening section (when you get up from the table), because that area gave me the lowest fps. setting it to all high and shadows to medium gave me 50fps lowest there, ultra settings would dip below 40. With Vulkan everything on ultra, rock solid 60fps, pretty insane, I hope more games add support.
There won't be much gain for NVidia with Vulkan in this game as NVidia did already great in OpenGL already. Obviously AMD has been notorious with bad OpenGL support, so because of that it will appear like they have larger gains with Vulkan in Doom.
I think id should fully uncap this game as I'm sure I can get more than 200fps in some indoor situations. It would also help future-proof this game.
Got a nice boost in performance it seems. Used the first part of the foundry on the balcony to test. All nightmare/ultra settings, 1080p OpenGL 4.5 - 78 FPS https://i.imgur.com/hpZbMmA.jpg Vulkan - 113 FPS https://i.imgur.com/XbbGOhw.png
I got a similar boost with my setup as well. CPU bottleneck perhaps? Some people with Nvidia cards have not gained any FPS and even lost some.
Vulkan offered a solid boost here. Before, I could average about 70-80fps smoothly in OpenGL. In Vulkan, I'm pushing 120 almost constantly. And in some areas, over 140.
Yes! Finally, DOOM works as it should! No more running in a window! Game runs ultra smooth now! Although, I just cant be happy now can I? RTSS does not work with DOOM and Vulkan yet it would seem. Need to do more testing but my standard setting is doing nothing for frame limiting. Still, a huge, huge improvement!
I haven't tested that yet, but I did notice that for some reason I do not get screen tearing when using Vulkan with v-sync off. Not sure how. Switching the game between borderless and window makes no difference either way I don't see tearing like I do in OGL. Running Windows 10 if that could have any effect on it. Curious if anyone else experiences this.
I've seen some comments saying that 1080p res shows gains, and anything above can be negative with Vulkan on GTX 1080. Not sure yet if that's true, but worth testing.
I'm really glad to hear that the Vulkan renderer took care of the v-sync crap on AMD cards. I had a 390 previously and that V-sync thing drove me nearly insaine. What really irks me about it is that there is no reason OpenGL adaptive v-sync can't work on AMD... but anyways glad its not a issue anymore.
Dunno what it is about this game on my system but even with this latest Vulkan patch I still experience the following issues (on maxed out Ultra/Nightmare settings at 2560x1440 with the game installed on a 2 TB Western Digital Black hard drive): 1. Tediously long initial loading times to the main menu... seriously it takes around 3-4 minutes before I can even access any options! Why are there too progress bars here anyway? 2. If I go to Mission Select and pick The UAC then after another long loading time of around 2-3 minutes the game starts running at 13 fps using under 15% GPU and around 25% CPU. This 'bug' can be replicated every time. If I resume by save game then the game runs at 100+ FPS (with V-Sync off). 3. The game takes over a minute to quit to the desktop suggesting that it is using a lot of memory, possibly page file space but yet I have 16 GB of RAM. Qutting the game then reloading results in quicker loading times but they are still far too long when playing a level for the first time.
Results are sketchy at best. Some users gain fps, others lose... I think it's best to wait for future updates for the API,might see better results overall then.
I have noticed the same thing when using Vulkan. My guess is just a bug, either driver related or the game.
Thanks, changed a few things that might be causing it, like AF, AA, rendering mode etc but was the same throughout Not to worry, only really noticeable on plain backgrounds
Maybe it's just me but with the lack of performance improvements in DirectX 12 games (mostly due to a lack of asynchronous compute support) and now Vulkan showing little or no improvement over OpenGL on NVIDIA cards, I can't help but be a bit disappointed. All that hype and for what? Seems like AMD are taking all the glory currently with DX12 and Vulkan while NVIDIA act as if they don't care (or maybe they are just too busy releasing lots of new and very expensive graphics cards?).
After testing indoors area in single-player, I can now say that Opengl still provides higher fps. The difference is around 5-15fps. While moving around, Opengl consistently gives a higher highest fps (180+ vs 170+). This is with everything maxed out, highest AA 8x and 16x anisotropic, both nightmare settings, 130fov, 1920x1200. Will report back with outdoor scenario.
