AMD to Fix GCN Latency Issues with Driver Updates

What is interesting is I just tested my card with Unigine Heaven turned all the way up, and I am getting 90C @3000RPM as well, but my card isn't crashing at all.
I wonder what actually is the problem that causes your XFX to crash. I have all the cases fans turned down at the moment.

Edit: @1050/1500 it gets up to 96C and the card is still going

[amdftw]

I have no latency issues with my 7970.
But i will happy if any performance boost come again.
GTX680 ass kicked for a while, with new driver NV again fall deeper and deeper...

Have you tried to change the screws? I've had to change some on my own because the standard screws were longer than needed and the die had poor contact with the heatsink. Even 1/10 of a mm can make a difference in cooling performance.

So, the GCN cards have been out for over a year and AMD is only now just starting to get a grip on the drivers? That's rubbish. The drivers should be pretty much optimised on the day of release, with only a few bugs here and there to fix. They're certainly not getting my money, that's for sure.

I remember when I compared my then current HD 4870 512MB with an old GTX 8800 I got used three years ago, how much smoother and more responsive the nvidia card generally felt even though performance was lower. I see that nothing's changed and I'm sticking to nvidia.

They need to fix the overdrive features... Occasionally, its gets buggy and you have to uninstall the drivers. On top of that use driver sweeper. Reinstall the driver suite. It works again. AMD needs to fix this.

Am I the only Radeon user who never noticed any kind of sttutering?

They haven't fixed it since I owned Radeon 8500/9200 oh pardon... 2600XT?, oh 3850?, oh 4850? nope... was it ever been working like it should?

That's why, I think, this beta is so long in approval...they have to test literally EVERYTHING, since such a change can drastically affect how well things run.


If it's not...well...maybe it WAS them. Funny though, since Microstutter has been complained about for years now, and AMD has finally admitted to it?

That is literally what microstutter is, large variations in render times, which many said they could not detect, so AMD ignored it.

What Tech Report did very well was present this in a way that was very understandable, and with benchmarks. That deserves a pat on the back, for sure.

I agree, regardless of new architecture the drivers should be at an optimal performance without compromises such as noticeable image corruption which has lead to pointless RMAs for some people.

Since I am noticing large improvements since the 12.8s I'm sticking to AMD.
Was pretty close to going to nVidia though near the end of 2012 despite my last nVidia card was a POS.

With all the driver problems? ATi has/had at least they never put out a self destruct driver.

Good job to the people who presented the issue and good job to ATi for stepping up. GCN looks like it's only gonna get much better in the future

Since when is anything pretty much optimized on release. I will only use games for example. How many patches on average do AAA titles have in their first month of release. Skyrim had 3.

From TR`s own benches, the 7970 GE is faster and smoother (99% sites confirm this including TR). The 7870 and 7850, 7770 or 7750 is not affected. The only card TR stating is effected is the stock speed 7950 @ 925mhz (overclocked ones have not shown to have problems). The 660TI was the highest clocked card tested against. The games tested were few and BF3 and other major games have not been shown to have any problems but 2 games which are BL and Skyrim (Skyrim doesn’t count since it was run without VSync which breaks the game), so we can assume AMD is faster and smoother apart from the few cherry picked benches TR have shown until otherwise proven or shown. What people forget is; nvidia were not smoother in all the few games tested

On TR`s site, Amd 6 series were smoother than the nvidia 5 series according to the benches they have, yet we had people saying the nvidia cards were smoother? So which is it? I think it’s all in the head, or people imagining stuff.

thing is not everyone experienced microstutter, but from sounds the driver probably just needs to be built from the ground up and a separate set be made for GCN and VLIW

[Prima.Vera]

I only noticed big stutter on crossfire configs with my 5870/5850. Even if I was running 60+ fps I can feel sometime that is getting sluggish for a fraction of a sec, like the movement is choking, Really annoying especially on car games.

How can it all be in people's heads when AMD's David Baumann confessed to this problem himself, saying it was due to driver issues with GCN?

[EarlZ]

At least they are admitting that they have terrible drivers, though this issue has been around for the longest of time. This is actually good news if they can fix this, gives nvidia more reason to lower their card prices

[Jadawin]

Now, I don't care about AMD vs. Nvidia or AMD vs. Intel or any of that crap... but if I need a high-speed camera to detect latencies I can't notice on my own and which therefore didn't bother me at all, wouldn't a fix for this "problem" be just as undetectable for me without a high-speed camera? An undetectable fix for a undetectable problems (for most people)?

[EarlZ]

Maybe what they ment is that its easily detectable by a high speed camera that AMD's rendering interval is pretty bad. at 60fps with a dual 7950 I can easily feel/notice micro-stuttering even on a single 7950.

Denial and brand loyalty is a powerful thing.

Even linking to original article induced rage.

Well, THEN it is a real problem for you, no doubt about that. I just wondered because if it would be a huge big problem for everybody, it would have been noticed earlier and would be headlines everywhere. So it's a real problem for people with real good perception.

Skyrim was stuttering on my 6970 when the load on the card dropped into some scenes due to v-sync and I think the same issue I'm having with 7950, but a little bit less annoying.

My last two nVIDIA cards were a couple of GTX470 (not in SLI). I believe that in most of the games that I've put them through, there was some amount of stutter if PhysX or other Cuda functions (JC 2 for instance) were ON. With 5850 + GT240 for PhysX it was smooth as butter, so I suppose it was a problem regarding resource allocation or something like that. BFBC 2 run with less stutter on my 5850 than on GTX470 although the last one gave higher FPS, especially with AA.
Other "weird" experiences were thanks to Ambient Occlusion, in some games with that option activated, it started to lag or stutter like it was a 20-25FPS or worse even though the actual FPS hit 33-35FPS or more, in others, there was no problem. A powerful card/GPU, in the exact same game, gave a better experience where others lag although the difference shouldn't be that high.

Right now with a 7950@1170/1600MHz I feel some lag or stutter in Sleeping Dogs with Extreme AA, The Witcher 2 with US, Skyrim at times, BF 3 under certain settings/maps (6970 was unplayable on Ultra despite it's 40-45FPS), GTA 4, MP 3 with MSAA, Far Cry 3 under 60FPS, Hitman Absolution with high AA levels etc. I think the problem hangs on AMD/nVIDIA heads but also on the game developers hands and how well they optimize the code. It's not that big of a tragedy as long as the stutter can be avoided by turning of a graphic or other kind of option.

BTW, nVIDIA also had a "stutter problem" with gtx670 and adaptive v-sync I think.

Thankfully AMD is working on a solution for it.

I keep saying this all time. If it's a big deal, why would it come to discussion only 7 or 8 months after the card was released?

Of course the 7950 had bigger latencies, it was stuck at 850/925 MHz, while the 660 Ti can boost to almost 1100 MHz. The card with higher fps will have the lower latencies...

How can the fps count be higher if the frames comes delayed to the screen? OC Both cards and measure the timings again.

[Calin Banc]

Well, you can have 30FPS with 33,3ms needed for render every frame or 45FPS with render time from 5ms all the way to 50ms and so on. MHz/MHz performance is not equal between AMD and nVIDIA, so it's not that the problem. It MAY be, if the core/architecture needs X MHz in order to give constant frame times rate and the card was clocked lower than that to begin with.

I know exactly what you mean, where it kinda slows down (like rubber banding or something) then speeds right back up. This is not limited to ATI, I first noticed it on Need for Speed games on my x1300 then 7900GS. This is probably an example of coding being the culprit.

I had this with the 12.8 drivers and my current card in NFSMW 2012 and to a degree in Saints Row The Third.
Disappeared in 12.11 BETA 11.
