RX 490 Speculation

Basically many 144hz monitors owners, we had to either lower our refresh rate to 120hz, or some lucky just to keep their monitor off when the PC was rebooting and until after it loaded into windows; or else while on desktop we faced artefacts and very bad flickering like you plug - unplug the power forming electric charges on the screen


A visit at the official forums you will see the extend of the problem and how many are raging there over the last 7 months. It only affects 1080s, and has to do with the default clock speeds on desktop.

it also affected the 1070. i had this bug on my 1070 and it was annoying..

Surprised we haven't had more talk on here about this card. Admittedly there aren't a lot of hard facts but what do you think it will be?

Is this just a stop gap before the full Vega cards are released or some oddity like a dual chip RX480?

If Vega is any good I may consider selling my 1070 and giving it a go. I do like the 1070, cool, quiet and fast but I think I'm an AMD man at heart. I like an underdog!

upgrade your cpu motherboard ram.thats the smart thing to do.

Would disagree with the many - though some are reporting the same problem - I've 3x 144Hz displays myself including both the Dell 2716dg, the original Asus ROG Swift and an older non-G-Sync BenQ 144Hz panel and various GPUs including the 1070 and not had anything like that and likewise know many people IRL and online that have zero such problems with similar setups.

The only case that was sort of driver related that I've experienced myself was solved by changing power management mode in the nVidia control panel from optimal to adaptive (or disabling a widget he was running).

what happened to drivers? when i got my first proper gaming pc i updated my driver less than every 3 months and everything was fine. why now do we need them everytime a game is released?

It's a marketing ploy by Nvidia. They released a game specific driver for Arkham Knight, a game that was bundled with the 980ti!

The only coding specifically relating to that game was the mention it got in the release notes.

do you have anything to back up this statement?
 
if you read the release notes for a game you can see this :

"Just in time for the highly anticipated title Grand Theft Auto V, this new GeForce Game Ready driver ensures you'll have the best possible gaming experience. With support for GeForce SLI technology and one-click game setting optimizations within GeForce Experience, you'll have the best possible performance and image quality during gameplay. In addition, this driver is aligned with today's launch of the world's fastest gaming GPU; the GeForce GTX Titan X.

Game Ready
Best gaming experience for Grand Theft Auto V, including support for SLI Technology and GeForce Experience 1-click optimizations "

whether that warrants a new driver or not, that's debatable.

SLI and Crossfire are on life support anyway at this point, so most of the time you'll get far lower performance.

Just out of interest why are they on life support?

I know most recommend buying the best single GPU you can as there can be complications but is crossfire or SLI really that bad. I wouldn't know as I've never tried.

It still works fairly well but it isn't as good IMO as at the peak of when I had GTX470 SLI - making it a lot less worth the value of the second card.

Back in the day you could get close to 100% scaling with CF/SLi

Now it's closer to 50%
 
Also whats all this talk about flickering and such on nVidia cards? Take it to the nVidia thread if u want to talk about that. Don't fill another AMD thread with nVidia jibba jabba please. Hard enough wading through posts of nonsense.

I first used SLI with the 8800GTX, 2 way then later 3 way. I also had 2900XT crossfire in another machine, before moving to 4870X2, then 2x4870X2 quad crossfire, then 7970 (single card) before back to 7970+7990 trifire, then 980 SLI.

So I've used SLI/Crossfire for a long time, it used to just work in everything and give good scaling, but games are becoming less and less AFR compatible, many AAA games no longer support SLI/Xfire at all or very badly. nVidia don't even support over 2 cards in SLI anymore.

I don't think multicards will be around much longer. If I were to buy a new card today, I'd look only at single cards, even if it meant a Titan X.
 
Thing is though, DX12 can be programmed to use multiple cards without even needing SLI/CF.

But no one has bothered with it (and I bet a certain manufacturer would put a stopper on their users being able to do it, like they did with activesync).

Of course developers don't want to spend more time on it. There's little return in it for them (at the moment). It will require AMD and Nvidia to get involved in the dev process, as they already do with post-processing and other graphical effects, to push mGPU.

nVidia didn't block this in Ashes. You can even use an AMD and an nVidia chip.

nVidia even said it would be allowed up to 4 way in DX12 in the 1080 release. It doesn't require effort from them.

However, other than the techdemo that is Ashes, I doubt we will see any other games bothering with it. Why would a developer want to take on all the work that is done by a graphics driver team as well, and have to patch their game for every new release.

It's not ever going to amount to anything.
