Doom Vulkan vs Open GL performance

Vulkan test on GTX 970 and RX 480 side by side

https://www.youtube.com/watch?v=Gq3fvT9KUNc

Its obvious from that video that he has an issue with the AMD card, i would hazard a guess he does not have A-Sync running correctly, wonder if he will re-run the test with A-Sync correctly working?

Seems to be vsync issue and Vulkan. Reading the steam FAQ for Vulkan they say about vsync making frame rate less than expected when using Windows 10 and vsync. They do only list two GPUs though but I very doubt it only effects them seeing all AMD GPUs run very similar hardware.

Windows 10 users running OpenGL or Vulkan on the AMD R9 Fury X znd R9 390X at 1080p or higher may experience framerates below 60 FPS with v-sync enabled.
While we are working on a fix for this with AMD, affected users should run the game with v-sync disabled.

*Vulkan is not currently supported on NVIDIA GPUs with 2 GB of RAM on Windows 7 or on the GTX 690. Users with these GPUs need to run DOOM on the OpenGL graphics API.

Most likely Nvidia gimping practises in effect there worried to release too much performance on there older gens ...so there holding it back tweaking until they can balance the performance across the gens ...

just a thought

tin foil hat removed :)

Yep and he will still buy Nvidia products. He probably paid almost double what i did for my 290. Yet i probably have a superior product.
 
Yeah Frostbite will be around October (as per my original post) assuming no issues, but nothing on road map for Cryengine considering they have not long released Cryengine 5 and have been struggling last few years it may be that it changes with Cryengine 6.

Sorry my mistake, thought we were talking about Frostbite, not crygen :o
 
I honestly question Nvidia and there support for Async Compute even in Pascal.

Why isn't it in Vulkan? A game they showcased at launch event for 1080 guess only running Vulkan minus Async Compute.

They lied before about Magic driver for Maxwell :confused: Do you guys honestly believe that Pascal has full support? TotalWar Devs dont know and now ID devs have said no support yet
 
Yep. £170 after selling the 4 games i received.

If we include games and stuff price comparisons get silly - I had about "£90" of games bundled with my card with the deal nVidia was doing at the time. Didn't you also get your card in the black Friday sale?

End of the day I had 2 years where my card outperformed the 290X Tri-X (which was £50 more than what I paid) until AMD cards started to make up performance (still a lot of games it matches or beats it other than recent titles) - job done. While it still holds up well enough today I'm in no hurry to upgrade its done its bit got my money worth happy to spend more to replace it if needed.

Yes this

I do not understand what nvidia are up too ...it just does not seem right to have a 10 series launch with doom on vulkan they where hyping this big time however the results where seeing here for nvidia is poor its not like they have not had enough time is it...

I lost trust in nvidia as a company years ago re BUMPGATE caused me endless problems with customers laptops and some dedicated cards and more so with all the recent fiasco's ...

Thx for the remind on the so called maxwell async driver forgot about that one ..

AMD is far more trust worthy than NVIDIA by far ...yes all companies can not be trusted but AMD have my money

do not get me started about gsync vs freesync costs never mind the overpriced 10 series

It amazes me people still throw money at nvidia but they do
 
^^ At the very least, assuming for sake of argument that nVidia "does" ASync it is far more complicated to get it work than on AMD where you can relatively easily throw it at it indiscriminately without encountering potential performance issues. Worth waiting a bit to see what they can/can't do with Doom and ASync on nVidia before jumping to conclusions.

Yes agree but it worries me this..

As in the past we have seen AMD lag in terms of getting there best performance out of new released games with nvidia usually having the lead on a game launch..

So we could end up seeing the tables turned with the new API's
my moneys on AMD

Definitely going to be interesting - especially to see the timetable of true next gen performance cards - as at the current rate that could make as much impact as the API differences.

Your gtx780 is struggling against a 7970ghz edition these days. Sure you can sayyou have a pre OC edition but i can OC as well and so does the 7970. In Dx12 games you are now a gen behind. My card is still pretty much up to date architecture wise while yours is old hat.

Could Nvidia go another gen without these key Low level hardware? So far All Nvidia lineup "ignore Pascal for sec" don't support Async What does this do for the future? All them 970/980 users for example will come 2017/18 be left in the dirt? God help if it turns out that Pascal dont support Hardware Async Another lie?

So meany Question, Just look at the Gain for that Goddamn 7950 in Vulkan lol if a load games release with Vulkan and if DX12 can get its performance sorted then the HOLE AMD lineup can make for a massive jump in performance! 7000 series and onwards.

I said this last night, AMD built their hardware with a lot of this tech in mind, they developed their own API Mantle to harness this tech....

Mantle got squashed but we have Vulkan and DX12 from its remains, while people will claim neither are anything like Mantle, i think we can all agree they share the same philosophy as Mantle did.

I am convinced that a lot of what Mantle was has been adpoted into these new API's, if the groundwork was already laid, you wouldnt scrap it and start anew, you would modify and work with what you could from that and remove what you did not need.

Now AMD have built their hardware forward thinking around this stuff, a lot of it probably was developed to harness GCN specifically, but the main advantage right now is AMD have this all in their hardware.

Nvidia kept faith with DX9/10/11 and have streamlined their hardware to focus on maximising this, gambling on DX12, Vulkan, A-Sync etc never really taking off, or at the least being enough years into the future that they could carry on being the DX kings in the present and gear up for the future.

I think they may have been caught flatfooted here with this gamble, as it appears AMD are now reaping the benefits, i think the real key was getting their hardware into consoles, everyone knows the consoles sell more games than anything else, dev budgets for console games are generally much higher than PC games, and with this generation of consoles the architecture is extremely close to PC, so AMD are also reaping these benefits and will continue to do so.

Something made me wonder the other day, Microsoft backed Vulkan... why? they have also promised a 4k 60FPS console based off we believe Polaris.. people were laughing... not so funny now is it? Its odd, but i think Microsoft would probably let devs use Vulkan on their premier console as it would sell games, they can still use DX12 for less fps demanding games, but in games where hitting 60fps @ 4K is going to be the major selling point, Vulkan is probably the clear winnner here, whether DX12 has this potential remains to be seen.

Anyhow it seems Nvidias refined DX drivers and lack of actual real hardware support for tech like A-Sync might bite them a bit going forward, and this latest vulkan thing makes me think Nvidia does not support A-Sync at a hardware level like AMD Does, and that Nvidia are probably more of a software based solution for this, hence the delay getting it running on their cards.

I'd be careful comparing the 780 numbers you see in the average 780 benchmark - which more often than not are at ~954MHz actual boost clocks on A1 cards - against my 780 - with the lowest GPU offset I can actually set in overclocking tools I get this:

e4yOdQV.png

My out the box boost gives 17.8% higher performance and the lowest I can go is still at around 6% higher clocks than the cards those benchmarks are usually running :| and my card still has around 10% in the tank for overclocking compared to the image I posted just now in comparison to the 480.

(EDIT: My point being that the B1 780s, atleast the GHz and EVGA editions, etc. should really be looked at as a newer generation of cards as they are usually doing around OC'd A1 card clocks out the box and still have the same kind of ratio overclocking potential on top).

I can't see Maxwell doing well for DX12 types games ever - when it comes to ASync the architecture is only ever going to compare to 1+1 in a GCN format with a little bit of clockspeed advantage - even Pascal realistically is only the equivalent of 1+2 but with a big clock speed advantage at the moment.

Once we are on DX12/Vulkan proper developers are going to be targeting the 1070, 1080, future nVidia big GPUs which aren't that far off and AMD's Vega, etc. based GPUs whether you are talking 290(X), 970, 980 even to a degree the 480 and 980ti they are going to have to make sacrifices and won't be upto running max settings at good performance - its the way it has always been.

EDIT: My point being IMO people playing the latest games well into 2017/2018 with a 980, etc. and expecting to run higher settings with good performance are expecting a bit much and while the equivalent AMD cards may or may not do a bit better it won't be better enough to offset the need for a newer card to do the games justice.

Those of you , who don't see benefits on nvidia 1000 series cards between OGL and Vulkan, try lowering shadow quality from Nightmare to Ultra and you should see big difference.

Think it is more than that - fair few people running ultra (not nightmare) on a mix of cards where 1 person is seeing 20-30% gains and another on the same card/similar setup sees nothing or even spots of degraded performance.

I like your sympathetic nature and real nice to see your feeling for Pre-Pascal owners :D

Is there a multi card test out so that we can see what is what across the board?
