OP, did you download the new AMD drivers that came out specifically for Doom?
Thanks I didn't see it mentioned in the OP. I have a 290x and have been thinking about getting Doom and saw the hotfix this morning.Yes.
From what I gather, the game uses OpenGL 4.5 for Nvidia GPUs and OpenGL 4.3 for AMD GPUs so that probably contributes to the performance weirdness.

I guess I'll wait for the Vulkan update before buying.
AMD struggles with OpenGL, which is one of the reasons they handed Mantle over to Chronos group as the starting point for Vulkan.So it's pretty much the opposite of Quantum Break?
2500k @ 4ghz
8gb DDR3 1600
R9 390
i experienced this in the open beta. everything maxed and while my fps read a constant 60, i was having microstutter (if thats the word used to describe it) at times. kind of bummed. started my download before heading to work this morning and was looking forward to playing when i got home. i guess ill see how it goes.
RAGE had severe issues with AMD at launch too
That's really shady. Not only AMD is very bad, but you can see that a 960 almost is on par with a 780 Ti. That's just plain ridiculous.
A 970 that at release was around 25% faster than a 770, in this game is more than 100% faster. This is deliberate performance loss.
It's what it would look if Nvidia paid them for maximum profits.
Now... I expect Vulkan to come out and work specifically only for the 10xx videocards, while running even worse on everything else.
I hope this is not the way PC gaming is heading toward.
Yep, it's the engine.
I'm a 390x owner and managed to really improve my performance by updating my mobo bios and installing the newest drivers.
Game runs nearly flawlessly now, but I think there's some improvement here for AMD to shore up.

Game runs bad, always Nvidia's fault. It couldn't be that AMD's OpenGL support (that this game happens to use) has been shoddy...
Yep, it's the engine.
I'm pointing out that Nvidia is deliberately avoiding optimization for everything beside the latest models.
Yes, it's Nvidia who wants to maximize sales and so stops optimizing just so customers continue to buy new hardware on even shorter cycles.
The performance of 7xx Nvidia cards is right on par with AMD of the same level, and it's quite evident what is going on.
Go look at the beta benchmarks and you'll notice that only the 9xx made a leap forward, every other card showed no improvement at all.
The driver was put out as fast as possible to meet the game launch. Have you considered the possibility that they didn't have time to add kepler specific optimizations(which it is highly dependent on) for the game yet?
Then why does the game run fine on the AMD hardware in consoles?
It's not really their hardware that is at fault. It's AMD's implementation of OpenGL in their Windows drivers. Pretty sure that the PS4 doesn't use OpenGL for the majority of the games on the platform including Doom, even though the hardware can support the API.
I know. And the PS4 doesn't support opengl at all.
In guessing zero chance this game gets a PC demo to try it out. I suppose Steam refund would work though
Hmm... I would have thought that the GPU in the PS4 would still be capable of running OpenGL since it is based around a 7970.
The PS4 has two graphics libraries, called GNM and GNMX. GNM is a low-level API not unlike Vulkan or DX12, GNMX is a wrapper for GNM which is a higher-level API that closely resembles DX11.
There is no need for OpenGL on PS4 because Sony already has both low-level and high-level API access covered.
Will wait for Vulkan.
Ah OK. Yeah, then it makes sense why Doom would get better performance on the PS4 over an AMD card (relatively speaking). The PS4 port of Doom isn't using OpenGL in anyway.
This is a fun read, maybe. I dunno. I don't know anything about what this guy is talking about but he talks about it in a fun way.

If you can't figure out who Vendor A, B, and C are then I'm not sure what I can tell you.
I still find it interesting that the first demonstration of a game using Vulkan (DOOM) was shown on an Nvidia GPU (1080) and not an AMD one, despite the various claims that Vulkan is thinly disguised Mantle or something like that. Apparently Nvidia are better at developing drivers for AMD's API than AMD are.
I thought AMD was pretty well known for not being good at OpenGL? No one uses it anymore except ID so that's probably why people are caught by surprise like this.
It's an issue that goes back to the days when they were still called ATI.
Sorry to hear that OP, as stated AMD consistently has issues with opengl based games when they launch. My 980ti had drops to 30 in a few key areas and situations before their driver update today, so I hope AMD is working a driver fix too. I dealt with my share of performance disparities on my old 7970ghz against comparable Nvidia cards in numerous games so I know how you feel.
AMD has issues with OpenGL. The Vulkan update should fix this.
AMD cards generally get worse performance with OpenGL than Nvidia cards do, and this has always been the case. Hopefully Vulkan support will be a solution for this issue.

Once the Vulkan patch is out performance should increase across the board.
The general consensus from the Dolphin devs seems to be that AMD's opengl implementation isn't very good.
AMD's basically never been able to write proper OpenGL drivers. Their Linux performance is terrible because of this, R9 290's benchmark about as fast as 660 Ti's in some games because of how terrible AMD's OpenGL drivers are, especially when it comes to CPU utilization. Normally not as much an issue on Windows since practically everything uses DirectX, but iD loves them some OGL.
OpenGL is dominated by Nvidia (even more so on Linux systems). Maybe it'll change with Vulkan or new drivers but I doubt it.

Can you please tell me what you are trying to show me?
He is suggesting AMD does not traditionally struggle on Id Tech (even though it is OpenGL), so we're hopefully one driver update + one game patch away.Can you please tell me what you are trying to show me?
I'm going to guess that AMD does pretty well in those benchmarks
They do indeed. Then again my problems for example with The Old Blood wasn't performance per se, it was more that I couldn't for the life of me get rid of either mad microstutter or bad tearing. Hmm.
See now those are the problems that I am having. I don't care what benchmarks show any GPU running at insane framerates if there is microstuttering or tearing. Do benchmarks show that stuff?
Have you tried the VSynch/Tripple Buffering options in the Crimson Settings/Driver program by the way?
