Except it does not mean more momentum behind consoles. Until we see AMD (and thus Sony/MS) talking about Mantle on consoles, it's little more than a pipe dream and speculation.

And if we're going to speculate...I highly doubt MS is going to allow Mantle on its own console.

He didn't say anything about Mantle on consoles. He said GCN on consoles.

I don't think you understand. DICE say development of FB for mantle and ps4 will be similar if not the same.

Coding for mantle is "similar if not compatible" with ps4 according to amd.

Remember there is a top level (the old dx way of expressing it btw) dx part in mantle.

If oxide can gain 3 times performance improvement on the cpu side in a rts in 2 man-months for a game engine made for dx, i have no trouble imagining the cost of porting from the consoles, that have the same hardware and very similar api to mantle, is very low cost bordering on the insignificant. Thats what the last 2 months have showed us.

Now we just need to see our selves what the gains is.

Yes it is, completely distorting reality while pretending we all run around suffering 15 fps in games with the fastest video card on the planet.

Yeah that argument makes no sense. The point is that, for the vast majority of people today, FPS drops in the mid-to-high 30's to high 50's range (starting from 60fps or above) will cause gameplay to be less than smooth (for reasons mentioned earlier). Using IQ settings with an average framerate of 20-30fps is crazy because the framerate will by definition drop well below that.

What I'm saying is that if *-**** allows Nvidia users to increase IQ up to 40 fps like Blackened suggested it would, then the dips will just end up even worse. They are already pretty bad, for some reason the Ti's minimums just appear worse than the 290X's already.

Look at the latest [H] benchmarks, I'm sure you've heard all about them by now.





Half of them have dips to 30 fps. Increasing IQ to a 40 fps average isn't going to help that, it'll be much worse overall. Mantle on the other hand *might* be able to maintain 40+ fps far more consistently - at least that's what we're being led to believe by guys like Katsman - https://twitter.com/AMDGaming/status/400401852090417152

Quote from Ryan at pcper.com as part of podcast #283 (about 37:30)
"up to 45% faster BF4 with Mantle"
"That is on an APU not a discrete GPU"
" I think a high end discrete GPU with a high end CPU will be much lower"

Interesting since he has seen more than we have in the secret presentations.

We've already ascertained that the 45% increase was with Kaveri and a 290X.

http://forums.anandtech.com/showpost.php?p=35954563&postcount=4612

edit - and it wasn't a peak of 45% either like some were suggesting. That might well be the best showing for Mantle in BF4, ie the scene that shows the highest gains (hence the "up to 45%") - but it'll be an average of 45% faster (55/38) over the entire scene and not some one-off peak.

Kaveri+290x is proven by the slides. Nice try bashing mantle with random quotes all over the place. And thanks for showing pcper is either biased or plain stupid so never gonna use it for a reference now.

SW - Like most of us here I'm very curious about mantle and it's potential impact, but where are you coming up with your numbers. I saw the same pr release that everyone did, saying upto 45% gain. But now you are saying that the 45% will be the average gain. Are you just hoping, or do you know something the rest of us don't?

Sorta makes me wish I had stayed with my 2500K instead of upgrading my whole platform. BF4 is literally the only CPU-bound title I'm playing right now. Should have saved the upgrade until next November and gotten a second 290.

Whatever though, I'm not gonna cry over spilled vodka. It's not like I wanted to burn my house down anyway

It's how AMD does their benchmarking. If you look at older slides for their APU's, they do a run of 3dmark or something like that as a comparison point. That's the whole run of a 3dmark scene - not just grabbing the peak increase and using that as the result to show the best case.

They'll have done a comparison (DX vs Mantle) of the entire game, chosen the scene or level where Mantle performs best then used that as the "up to 45%" perf increase. All other scenes will likely be less than 45% faster - perhaps not by much, perhaps by a lot, I just don't know.

You just don't get it do you. To have truly smooth gameplay on most systems today (meaning minimal stuttering/tearing/lag) will require a framerate that is >=60fps at all times. That does not mean an avg. framerate of 60fps! An avg framerate of 60fps by definition means that framerate goes above and below that point. So the point is that, instead of requiring an avg. fps of say 80fps (with dips in the 60-80fps region) to have truly smooth gameplay (as defined above), one can turn up IQ settings to have an avg. fps of say 60fps (with dips in the 40-60fps region) while still maintaining smooth gameplay.

In a fantasy scenario where you would never drop below 40 fps, yes. Meanwhile look at the graphs and you'll see dips in the low 30's with average 60 fps.

You are much more likely to get "smooth" and consistent gameplay with Mantle being consistent at 60fps (even at 40fps? -we'll see), compared to That Which Shall Not Be Named attempting to maintain a 40-60fps range with a broken API that causes massive dips and stalls.

Ugh no, this is contrary to what every FPS gamer knows by heart, you do NOT want dips that low when you're busy getting killed or trying to kill. A lot of online gamers will sacrifice IQ to maintain consistent >60fps in all combat situations. The last thing you want is going from 60 to 30 or 40 and you're in a firefight.

@ SiliconWars: you still don't get it. Any dip in the 30-60 fps range will result in smoother gameplay vs. not having the tech. And if framerate drops below 30fps, the gameplay will never be smooth one way or another.

You must be smoking something hallucinogenic to suggest that Mantle will magically cause fps to dip no lower than 60fps. As long as fps drops below 60fps, Mantle cannot resolve issues related to tearing/stuttering/lag that are fundamental to the monitor tech.

Read what I wrote. In systems used TODAY, one needs to have fps dip no lower than 60fps to avoid tearing/stuttering/lag associated with fixed monitor refresh rate.

Exactly, which is why this whole point about increasing IQ is nonsense. The higher the IQ the more likely the dips will be worse.

The point would be that Mantle enabled games are more likely to be running constantly above 60 fps than the other solution due to 1) Much higher base performance and 2) Far less issues with stalling that DX suffers from, meaning no horrible dips in to the 20-30fps range or lower.

No it is not nonsense. Instead of dipping to 60fps min, one can dip close to 30fps min with minimal stuttering/lag/tearing. That means higher IQ period.

And with Mantle you just won't dip to 30 fps because these dips are mostly DX related.

Let's say 30-40 fps on the Nvidia solution is the same as 50-60 fps on the Mantle solution in terms of image quality, smoothness etc. This is something that Mantle is capable of maintaining while NEVER having the sub-30 fps dips that the Nvidia solution will sometimes suffer from.

Here : http://www.hardware.fr/news/13525/ces-45-version-mantle-bf4.html

They say that 45% is not the maximum. It can go higher in some special cases.

I'm not saying it's 100% accurate, just passing the message

No one can say that without actually measuring that. Anyway, DX related overhead has improved significantly over the years, and will continue to improve. Next gen GPU's will also have unified virtual memory so that there will be more efficient utilization of CPU and GPU.

Hey now, let's not get ahead of ourselves. We don't know that.

Ok let's say it's not DX related - but what else could it be? Possibly running out of memory - but Mantle shows full-scene information so that should not be an issue either. Slide 7 - http://www.slideshare.net/DICEStudio/mantle-for-developers

All recent quadcore and above CPU's should be basically equal under Mantle, so it won't be a CPU causing the stall. Given what the devs who use Mantle are saying, we should reasonably expect smooth gameplay with none of the really annoying dips in fps - which let's be honest is what actually matters when gaming.

There is no way to magically ensure that fps never dips below 60fps, because that depends on how high the IQ settings are turned up and how powerful a GPU is being used.
