Title: DirectX 12
Post by: Data on May 06, 2015, 13:08:00 PM
DirectX 12 is coming soon but only to windows 10 it would seem.

So what will it give us over DirectX 11 ?

Better frame rates and lower power consumption is it's goal and it could be achieved using the same hardware.

Lets see if our win 10 computers are ready for Direct X 12, apparently in win 10 the dxdiag.exe tests your hardware and driver for compatibility with DX 12, only if they all pass the test do we see version 12.

Type " dxdiag " in to the start menu search then run dxdiag.

Here is mine and it did pass  :)

I got DX 11.2 for some reason  :scratch-head:

Must be because I'm using an old AMD driver.

I had a feeling yours wouldn't pass as DX12 Freddy, yup it must be them older drivers  :(

Nevermind, by the time I need it I will have a new card.

No support from AMD hasn't really impressed me. No help on my thread, one email to ask how I got it to work then nothing. They had to ask me.

Sounds like they are on the case then, I doubt you are the only person with the problem,  it must be quite a task to test for all possible configurations when a new OS is released. 

Roll on Catalyst 15.8

This is true, but it's not good to not reply to emails for a week, then two weeks imho.

You have done your bit mate and reported the problem  :thumbsup:

Have a look at this report on AMD cards and DX 12

QuoteFirst DirectX 12 compatible game shows significant performance improvements on AMD graphics cards.

As evident in the charts below, gamers with AMD graphics cards in particular are in for a massive performance improvement.

There has been some controversy recently over Dx12 and graphics card manufactures, not wanting to take sides, have a look at these vids.

A bit of time has passed and some more useful (to me) information is coming out.

How Many Cores Do You Need For DirectX 12?

The best solution seems to be 8 physical cores

! No longer available (http://www.youtube.com/watch?v=HOevOiJUQAE#)

However, them 8 core Intel CPU's are a shed load of cash.

AMD will be releasing their new Zen range of CPU's soon and It seems to me that they might have a master plan, with 8 and 16 core versions, no onboard graphics, they might know something we don't.

Here is a good video that explains a bit about Zen and it's speed, it's in an English that most will understand.

! No longer available (http://www.youtube.com/watch?v=kpEK8rOjC6A#)

So basically it looks like AMD might have caught up intel and quite possibly have a better bang for bucks CPU for DX12 gaming. Looks good to me, some serious competition to Intel in the CPU market.  8)

Have you seen anything yet about dual cards being able to combine VRAM yet ?

It was something DX12 was supposed to do.

Post by: Data on March 03, 2016, 01:00:12 AM
Nothing seems concrete when it comes to Vram stacking and DX 12, last I heard games might have to be specifically made to be able to do it, from what I can gather it might be a bit like SLI and Xfire "a bit hit and miss depending on the game".

I have no idea about Vram stacking and video rendering though.

Here is an up-date on DX 12, some good news in there, like being able to run AMD and Nvidia cards in the same computer at the same time in games. The bad news is that Nvidia cards are now showing their downside, no "asynchronous" support for DX12 and it looks like they are trying to hide the fact with Gameworks.

Watch it all but don't shoot the messenger  ;)

Found this video today, at first I thought it was just another DX12 video, ok in some ways maybe it is but it's delivery of the benefits is done in a "straight to the point" way.

  Buy a new graphics card and you can use them both, pretty nice.  I wonder if they will ever do that with CPUs.

There is a new DirectX 12 demo benchmark test to download, if you want to.

Interesting concept, but I wasn't thrilled with the overall appearance of the video, TBH. It was severely washed out, and there wasn't much in the way of discernable fine details as a result. Frankly, it looked at least 4 generations old.

Or maybe it's just my eyes. We've had a LOT of smoke in the air here, from several fires in the area. Who knows? I'll look again once my eyes stop burning.

I'm struggling with that statement  :scratch-head:  :LOL:

But not as much as my graphics card is struggling to run the benchmark.

I scored 1722

Still it's good to know my rig will run DX12 but I'm going to have to knock down the quality settings to get good frame rates, it would seem.

What's tripping you up there, Data?

My criteria regarding that statement was colour vibrancy and detail, both of which were lacking, to my eyes. but like I said, it could just be me.
Title: Re: DirectX 12
Post by: Data on August 14, 2016, 15:16:10 PM
Maybe it's the video not doing it justice, when you run the benchmark you see all the tiny detail in the glass cabinets, to me it looks packed with detail, it is showing off DX12 and the amount of draw calls and polygons it can get on the screen. All the silvery crystals it draws too, the fogging and light flares.

Well I was impressed but that's not hard to do  :D

It's got to be my eyes, then. Sad, really, but it also means that I may never have to upgrade my vid cards again. :P Still really smokey, though, so I'll weigh back in here when it clears.

Do I detect a bit of playing "devils advocate"  ;)

I doubt all new DX12 games will have all effects turned on all of the time.

Nevermind, I was running the wrong installer.

Mine scored...

Graphics : 3669
CPU : 6368
Overall : 3918

It was all a bit jerky.

Impressive score there Freddy, especially the CPU  8)

Your over all score "Better than 38% of all results" it's a sad fact but our GPU's, well, especially mine have fallen behind now  :(

Still it's good to know we can run DX12, it's going to be the future DX12 on 8 GIG cards.

I won't be upgrading my GPU for a while as yet. Does what I need it to for now.

I'm frightened to even try, as I'm certain I'll get a much worse score. :P

Dave. I'm pretty sure your cards can run DX12, obviously you need windows 10 and the latest graphics card drivers.

Lets take it as read that it runs and gets a nice score   ;)

Data, your comment kind of goaded me into giving it a try. :P

was going to finally deliver the file ONE DAY later. :eeeek:

So I searched for a faster link:

http://www.oldergeeks.com/downloads/file.php?id=866

I actually got the link from the FutureMark website's list of mirrors. It's downloading now, and should be ready to use in ~10 minutes. Still "slow", but far faster than waiting a day. :D

Had some trouble with 3dMark. It says there's an update available, but it would not install. Tried several times, no love. Here's the results:

http://www.3dmark.com/3dm/14232324

As expected, terribly sad. The demo was so choppy it was painful to watch. It got down to less than 2FPS, and the 2 GPU benchmarks were not much better, as you can see. The CPU test started of slow, but acceptable, but then it, too, started to chop badly, going as low as 9FPS. :sign-sad:
Title: Re: DirectX 12
Post by: Data on August 19, 2016, 12:39:55 PM
Your overall score is almost the same as mine Dave, it's your GPU's that are letting it down, the CPU score is good still, I think.

These demos are always tough to run, I'm not surprised they run a bit choppy.

Still it run the test and your rig can run DX12  :thumbsup:
