Mantle Feedback/Bugs

LtMatt said:
Not speculating. Its called reading the release notes and known issues. You should definitely try it mate. When 7970/7950's were being sold, pretty sure Mantle was not marked as a feature so its definitely free for you. You should be able to use DX11 fine, you'll just have to wait a week or so before you get similar optimisations to what us 290 owners get.

But AMD were advertising Mantle for BF4 on 7xxx cards in December, when I bought my cards. And the release dates about the 7xxx series being screwed came out 3 days before the drivers release? Its February and I still can't use it. And I believe your 'or so' is more correct before its fully functional, R290 users are fully supported but still crash all over the place.

I am not wanting to debate when it will be fixed simply that it shouldn't have been released in the state it is in which is all we have to go on. As the large Mantle thread proved, too much speculation is a bad thing and people called for a proper thread. So now its been released this is what we have to base it on.

Are you completely happy with how Mantle has been released in its current state?

Well, if you'd been mining since December, like I have, then you'd have paid off your card(s) already :)

I think that it's good to get Mantle out now. It's an early beta and yes GCN 1.0 doesn't seem to work as well as the GCN 1.1 cards. That will be resolved in the coming months. As will crashes as AMD and the game developers iron out their respective bugs (DICE can't even release a general game patch without creating yet more issues to fix so it was asking a lot to provide a crash free Mantle experience.)

I'm happy that we've got Mantle because the earlier that we get it the more bugs can be ironed out sooner. That's how all public beta tests should work; unless you're DICE/EA and you just release it anyway even with all the beta bugs (this is just friendly mocking DICE, I know how hard it is to work with complex software and how easily bugs come from that.)

I don't honestly know if I saw gains as the FPS was the same, or a touch higher than DX but as X-fire isn't working and I didn't have afterburner up i'm not entirely sure it was using both cards in which case very impressive.

Just what :confused:

My point is the bugs here are more akin to an Alpha. Not supporting your largest card install base feels very Alpha to me let alone crossfire not working after the amount of hype gumpf about improved crossfire.
 
Wouldn't it be nice if more games included a realistic benchmark?
By that I mean not just using the engine, but actually using it in the context it's used in game.

I wonder how smooth the DirectX launch was back in the day, I really can't remember. I do remember that it didn't really hit anything like it's stride until about DirectX 3.
As for Mantle, this might not have been the most successful beta launch in history, but surely what's more important is how something ends up, not how it starts out? Starting first in an F1 races is great, but if you finish 20th or don't finish then it's not good. If you start out 20th and finish first then you won the race.
Mantle's success is far from guaranteed, but at least this is a start. Hopefully it'll get better. Hopefully it'll be good enough that someone makes an API to rival it (competition is always good).

Not sure about the occasional comments of "nice to see AMD doing something new". Meaning what? A graphics API, cuz that's not new, DirectX and OpenGL have been doing that for ages. Low level? I'm sure the consoles have had lower level ones for a good few years. If you mean something that is (currently) locked to requiring their hardware, I'm sure we all know Nvidia have mastered that art for years. If you mean the exact combination of things they've done with Mantle then I think a lot of companies are trying something new by that measure!

It also amuses me that so many AMD users moan about Nvidia users ruining AMD threads but forget/overlook when AMD users do it to Nvidia threads. Nvidia users are probably just as bad in reverse too.

As a 290 owner I have to wonder if this is 'free'. Didn't I pay for it when I bought my 290s that listed Mantle support as a feature?

As for the comments that BF4 is the only popular FPS around at the minute, you might consider Planetside 2. Takes a bit of getting used to and the graphics aren't as good, but it can still be fun (or so I'm told, I don't get on with FPS games).

On a side note, I like how now having lower frametimes is so amazing but before AMD implemented the frame pacing or even acknowledged the bug a lot of AMD users claimed they couldn't notice it :)

Their testing must be a little skewed or something in that case, Shanghai, 64 player (at least 95% populated) 1920x1080 full ultra with 4770K at 4.6ghz Single GTX780 @ 1006/6000 around 15 mins testing:

Frames, Time (ms), Min, Max, Avg
77770, 904468, 58, 113, 85.984

If I get chance I will re run with CPU at stock and see what differences I get.

Your data is almost worthless though because of the inconsistencies of multiplayer benchmarking. Unless the same person is running the bench following the same practices, its too inconsistent.

Really? I don't even remember Mantle being listed as a feature on ocuk 7xxx listings. 290 listings? Sure. If you can show me im wrong then ill stand corrected.

I'm delighted with an Alpha version of Mantle and a Beta version of the drivers. Its far from perfect and has a long way to come but its a nice taster of what's to come. Of course i would prefer it if it was the final version of mantle and the drivers were 100% perfect though.

I've had huge crashing after updating in DX mode.

And Mantle crashes eventually and plays poorly (7970)

Need to do some tweeking of settings first.

What can i use to view FPS in mantle?

So your argument is semantics, the designer of the cards advertising the feature as coming to X/Y cards is not enough. Ok then.

I am sure you would have been delighted with the drivers if you had your old 2x7950 or 7990. Keep drinking the Kool-Aid.

And of course I want perfect drivers, you wouldn't? :p

Despite that - Alpha bugs, not fit for public consumption. This is a feedback and bugs thread, we can only give feedback and comments on bugs for what we have otherwise its just speculation again.

I'll bow out now Matt. That's my opinion and to you its wrong and its your thread.

I can tell you that over a 15 minute bench any such discrepancies will be averaged out. As long as pgi was playing a representative 15 min snip of gameplay then I completely disagree that it's worthless.

Also think that's a bit rude as well :p.

It's all well and good comparing deltas but looking at the actual FPS figures they don't look amazing compared to what I'm getting on my 780.
 
I'm getting black screen crashes in BF4 in either mantle or DX. Tried the official drivers and getting the same after a few mins playing on stock card. Seems these mantle drivers have naffed up my install. Will re-image to fresh and try again on official drivers.
 
I've had no BF4 crashes on my 7950 and a smoother experience which I put down to the frame pacing fix for Eyefinity. Am looking forward to any additional performance gains for 7xxx cards (I have a second on the shelf ready for x-firing). I also tried Arma3 and found a smoother game on that title, again down to frame pacing (for example a jerkiness on the side screens has gone when flying).

I'm not taking sides on you guys But dont imo think because X starts a thread its theirs alone. The title is feedback reviews your as entitled to your opinion as anyone else ,But same goes for LT while you can both dicusss it without bashing its good :)

Running in DX or Mantle?

What game settings do run with?

Its not about being rude, its just common sense. I could run a bench of Shanghai though and likely score higher than both of you with my gpu at stock clocks, but as ive no idea what their benching procedure was, its also worthless. Multiplayer is inconsistent so either result is worthless as we don't know the procedure or playstyle of the people who did the bench. They might have spent the round in a tank. Pgi or yourself could have spent the round on foot. That alone will account for a massive difference in fps.
