anyway, this new gpu measure variable should be fine tuned and explained better for the mass audience becuase honestly, i haven see it myself for the first time, and i got a 120hz monitor and had gfx cards from both brands amd/nvidia


its there a way to record a video and "show" or explain the exact moment where this happen?!?! it should be a great help for everyone; that way we can know what to look for thumb.gif

and sorry for my english biggrin.gif
he's actually a very knowledgeable person who just happens to run nVidia GPU's...
that's all man, don't think too much about it as I see other forum members get more carried away than any mod I have ever seen.
just be you and post away..

Just fyi, mods can have opinions if we want. What we can't do is let those opinions influence the moderating process. We've still OCN members as much as anyone. We're also pretty much expected to follow the ToS tongue.gif

But there's also nothing biased about repeating what AMD said they were going to do and agreeing with anandtech about what that would cause...

What he said is what AMD actually has planned.

For those who are sensitive to the latency, they can use the slider until it's smooth to them. Others can leave it as is.

I have a feeling that a lot of people are going to be surprised how much better the experience is when they have shifted to latency control vs raw fps.

Did he really said, he added a modification between game, and a capture stage of the pipeline? Actually can someone with a high speed camera try dual AMD cards, just to verify theirs results? Any modification between pipeline, including FRAPS, or DRM can completely kill results.

Correct me if I'm wrong but doesn't frame metering present it's own input lag?

Not when you do it on an external device.

You can store stuff on HD, then measure it as you want. A camera recording monitor output will not introduce any problems either.

Addition of some marks into the image, for example by an overlay, would slow things down, especially on multi card setups.

Anything added to the driver and software stack adds latency. FRAPS adds latency, frame metering adds latency, enabling debug output adds latency. If you add a single function, call, or snip of code between the software and the driver stack, you add latency. That's absolute, their is no way to go around that. That is exactly what the latency measures, how long it takes a call to be declared (any user application) and the time it takes for that deceleration to execute and give results that the user (IE: You and me) to receive that result. All monitoring software has to do it's monitoring somewhere between the deceleration and the result, adding a layer to the whole operation.

[edit] Before any stupid thoughts are had, this added latency is ideally thought to be equal on both sets of hardware. So the added latency goes for both Nvidia and AMD, thus the test would be apt in measuring which card/setup has more latency. AMD has criticized openly about the use of FRAPS, since it doesn't say where the latency is located. For all they know, it could be a driver conflict in Windows. Just throwing that out as an example. Since latency was low on the Nvidia end, with the same system while the only difference was the drivers... AMD had to do nothing else but openly admit they have latency problems, that's why you saw the press release about it. So as a general "which setup has more latency" question, those work. As long as the base hardware and software is exact, you can get a general idea. This doesn't solve the problem of the game mis-handling the hardware, which could give a false sense that it is a fault of AMD. hence why they went out and talked about the FRAPS latency stuff, it really should be done with specialized software.

Guys, frame metering is what Nvidia uses to smooth out frames on SLI systems. Not the form of testing. I think you guys are misunderstanding what I meant.
