Doom 4 performance and discussion

Doom beaten in 101 minutes, in nightmare mode

Damn, and I am sitting here, waiting for crossfire support, but it seems that one 280x/7970 can already run this game on 60 fps :infinity:

 

I know borderless avoids screen tearing, and the game has borderless built in. Thats not why I want v-sync. I want it because it keeps the temps a lot lower and fan speed down. I already tried using radeonpro, and radeon settings to force triple buffering, tired its adaptive v-sync feature as well, dose not work on doom. Also tried using it to lock framerate to 60 without v-sync.

Point is if the game is supposed to have triple buffering its broken, either in the game in general or because of AMD drivers. I'm just hoping the Vulkan renderer handles this better.

 

Well, I don't have the game, but what is wrong with running it in window with vsync and using Borderless Gaming? Temps are still high?

 

NM, it still dose it even though the game says its windowed. I give up. Probably something that will never get fixed. Fingers crossed vulcan has a working decent v-sync solution.

Edit: Actually I just got it to work I think! It got rid of the borders and looks fullscreen but it says its still in windowed mode! Thank you!! I had never heard of that little utility

Yep that did it. Just loaded up one of the most demanding spots in the game and the framerate will now only dip slightly to 55FPS or so instead of going to 30 in the few spots that knock it down. That fixed it



I just tried that borderless gaming app. It wont get rid of the borders, I appreciate the link though was a good idea. Maybe it dosent work because its a OpenGL game. Not sure. Playing it in a maximized window really isn't to bad, but for now I'm just gonna stick with v-sync full screen. With the power saving thing turned off in radeon settings ,and clockblocker running the drops to 30 are really really rare. at least so far, and I'm almost at the end of the game.

 

Oh, damn. Hes good.

 

No CF/SLI ? its developers fault always, not the GPU vendors
Devs need to put it in Game, BTW DX12 will Fix this for CF/SLI users
That's Progress, i like DX12/Vulcan.
And i need full DX12/Vulcan H/W feature support not partial when i switch to Big Polaris this summer :ying:

 

Devs from Doom said that multi-gpu support is coming (search on google for doom multi gpu, you will find a lot of hits). It could be that they will do this with the Vulkan-update though. Putting time and money into multi-gpu support for an old API would be a waste IMO.

 

I think hopes are unrealistic regarding Vulkan for Doom. I don't think it's going to be the saving grace everyone is expecting, especially on high/highest-end systems. Following The Talos Principle's vulkan implementation, there's a good chance performance might actually initially be lower than current opengl. Even when there's a performance boost, it's more likely to show benefit for the mid/mid-high systems, than high-end.

 

What's that overlay? Don't remember seeing it anywhere...

 

@Seketh, it's doom's build-in in-game.

 

Is there a consol command for running a benchmark like Doom 3 had?

 

So is there a reason for the lack of Vulkan? I was interested until I noticed we are on a lesser version of OpenGL. I want to believe if we were also on 4.5 the framerate would be better.

 

You will have to wait for AMD to complete their OpenGl 4.5 implementation.

 

One of the developers said that AMD being on OpenGL 4.3 doesn't lead to a lower framerate, as it runs 4.3 with 4.4 and 4.5 extensions.
Could be true, could be lying, but he doesn't really benefit from protecting AMD.

 

Hot damn! Nice one AMD!

kepler eeleft:

 

I'd thought of running Doom with 2x HD7950 in CF mode on my 3rd rig (i7 2600K), but since there's no CF/SLi support yet, I'd taken both cards out and replaced them with a HD7970 (can do 1.1GHz OC). Less headaches and such.....it'd be interesting to see how my dual GTX Titan 6GB (2nd rig, i7 4770K) fare in this game.

BTW, whose bright idea was it to have only 6.9GB of the game in a single disc, requiring me to download the remaining ~40GB online? With my damn slow net speed, using wireless dongle), it's gonna take me about 10 days or so to download (overnight only) the rest.

Edit - Just checked out the garage section of the local forums in my neck of the woods, peeps are trying to sell off their GTX970/GTX980's/GTX980 Ti's left, right, and center while the going is still relatively good. Trouble is, some are still asking pretty high prices so the cards are not exactly priced to sell.

 

use a fps limiter like dxtroy to cap the fps at whatever yo want
amd drivers has added this feature but unfortunately it doenst work in doom at the moment

 

My 270X certainly did not get any 36% boost. More like 3.6% if even that.

 

Probably intel cpu.
