Has anyone tried RadeonPro for microstuttering?

[wand3r3r]

Has anyone tried this yet?

It looks nothing short of amazing (on paper) so if anyone has tried it yet let us know how it is.

Will this be the end of the microstuttering complaints, or not?

[SirPauly]

That example looks impressive.

It's a framerate cap. How else would the frametime values be so constant? So it really isn't anything new, this was possible years ago with Dxtory, Bandicam etc.

Obviously, scaling suffers with this. In the beginning of my SLI days I employed a limiter too, but now I don't because the compromise is too severe.

It's not just a frame cap there buddy. It is also even frame distibution. Not the same thing.

I have crossfire 7970's. When I get home, after I feed the animals, beat the wife and kid, I'm going to try this out and report back. I'm very sensitive to microstutter and always looking to minimize it's appearance.

Is this the same as Nvidia Adaptive VSYNC?

I don't know why, but it is the same thing. When I experience microstutter and I employ an fps limiter, the result is exactly the same. Even frametimes, no microstutter. I know it doesn't make sense, but I guess the framerate limiters have some distribution or timing function built in already.

So this appears to require limiting your FPS to some value below 60?

As an owner of a 120hz monitor, that would not be acceptable in any way. I try to keep my FPS pegged at 120 whenever possible. So far I've found adaptive Vsync to be very useful in this regard.

No that's not how it works.

First, we have to make a profile for the game in question. It's a good idea, we've discovered, to first come up with an average frame rate using a tool like Fraps. If the average is higher than your screen's refresh rate, then that refresh rate is a good limit for the dynamic v-sync. Otherwise, the average frame rate itself is a good number to use.

You have 2 diferent features: DVC (adaptavie vsync) e DFC (frame cap)

- New: Dynamic Vsync Control (DVC) support. This feature controls how vertical synchronization is applied at rendering time, automatically turning it off when frame rate is below monitor's refresh rate to reduce stuttering and turning it on when framerate is above or equal to monitor's refresh rate, improving smoothness

- New: Dynamic Framerate Control (DFC) support. This feature acts like a frame rate limiter with smoothness control, just set a frame rate target and RadeonPro will try to keep it as close as possible while maintaining frame rendering times close to each other to avoid stuttering.

I've been wondering about this too. That review showed it outperforming Nvidia's Frame Metering in SLi. Which is actually good for both camps because this is a software solution so I'm sure someone will get something similar going in SLi.

Not to start a flame war, but leave it to AMD to rely on a third-party to solve the issue. They should really build something like this into a real driver release. Even though there isn't an 'AMD' 7990, this would still be a big help for those with 7970 and 7950 CF setups. The results speak for themselves, and I wonder how many people have no idea this exists. I just heard about it when reading the same review the OP linked to.

Just to test out your theory, I will use Afterburner tonight and employ a frame limiter and post my objective results

AMD does kind of blow when it comes to support. I have a lot more faith in their actual hardware though. You know how many nVidia cards I have baked back to life?

[Bryf50]

Wow. This looks great. Can't wait to try it out.

Most AMD users do know it exists and Nvinspector is also third-party.

Most? Not a chance.

Some enthusiasts, sure.

It's exactly the same thing. What do you think is limiting the frames to a number under the full performance? Right a "even frame distibution" because the gpus are not the limiting factor.

The link to It has been on AMDs site for years and the reason the author has taken it up again is because AMD is sponsoring him..

There has not been a single enthusiasts forum i that i go to that does not have threads about it and im talking about enthusiasts as others don't know there ass from there elbows and they would not know how to use it anyway.
The same goes for Nvinspector, Afterburner, ext cc these enthusiasts tools.

[SPBHM]

I only have a single card, but I also used a framerate limit to have smoother gameplay in some occasions, using dxtory, or years ago "FPS limiter 2.0"

[cmdrdredd]

I'm sorry but limiting your framerate because you get microstutter is unacceptable. Now Nvidia doesn't have 100% elimination of micro stutter in SLI but it's a ton better than AMD without limiting your fps. This solution is not good enough IMO.

[lavaheadache]

I have no problem limiting my frame rate if it is above what my monitor can display. What is the purpose of 150 fps if you can't see them?

It's a frame rate cap. This method has always cleaned up microstutter fairly well, either by using in game console commands, inspector (Nv), and now radeon pro for AMD.

Use a 125fps cap for 120hz

This.

It SHOULD be an option for the card in the official driver. The fact that you need a third party is ridiculous. Kudos to the author for making it, but shame on AMD for slacking on not making it available for everyone.

In the beginning of my SLI days I would have disagreed, being overly enthusiastic about minimized microstutter. Now I agree. You would have to set the limit to your lowest fps, otherwise it won't work all the time. That simply destroys scaling.

But there is one exception:
If you're playing with vsync anyway and still get stutter, you could limit to 60fps which can also help.

[lavaheadache]

a hah hah hah hah haaaaaa yes!!!! Just ran crysis 2 maxed out @2560 with crossfire 7970's with zero detectable microstutter (to me anyways). Just used a simple frame cap in Afterburner and voila!!!!! Finally after all these years of me bashing multi gpu I will actually start recommeding it. I am a believer. I'm actually going to go back and fire up some of my old rigs to see if this will work for them too.
