[PCPer] Frame Rating: GeForce GTX Titan, GeForce GTX 690, Radeon HD 7990 (HD 7970 CrossFire) - Page 11

zGunBLADEz, I give up! lol

The more and more this goes on, the more I figure you probably haven't read and understood the articles? Go and play BF3, at your 100fps, that true 100fps that all of these articles show. It's not about letting a card go 'berzerk', the point of a new testing methodology is that FRAPS benches are not telling the whole picture, simply measuring raw fps at Present() calls isn't what you're actually getting.

Not that any regular consumer has the tools for this, but that is basically the problem as I understand it.

You're right, they're not the same, sampling output provides a much better picture as it's at the end of the pipeline and is more representative of what the end user will see. But I've been arguing this for days now and I feel like I'm repeatedly hitting myself in the face with a brick rolleyes.gif

Ill read the article but you dont understand what capping frames do...

Not only remove the frame latency issues it also remove input lag as well...

vsync/cap frames would net you a same graph on fraps as fcat...
So is really true 100fps..

Do you notice any difference in the graph? other than the 2x7970 setup displaying 20 frame avg>>?

Which i still think the tool needs work because animation perception alone would tell you otherwise.

Yeah, only the second graph shows less variance in the CF w/o Vsync graph. Which kind of makes sense, since Vsynch regulates the frame buffer. Less likely for runt frames to show up since the frames are put in sequence rather than a best effort output.

E:

Putting frames in sequence introduces additional latency. With vsync you should experience more "input lag" btw.

Yes and no..

You can either use
1: normal vsync <== this usually indeed creates input latency in any card..
2: you can run without vsync and cap your frames this will smoother your gameplay aka skyrim fix before fixed drivers
3: you can try radeonpro dynamic vsync...

Like me and my issue with gamepad vs kb/mouse...

If i dont use dynamic vsync mouse/kb input lag is horrible

Vsync does not decrease latency, if anything it increases it. It only decreases the display interval if there is a problem with your drivers. To be honest, it sounds like you made up your mind before you even looked at any of the data.

Whos is saying vsync lowers input lag?

vsync and capping frames are 2 different things..
rolleyes.gif

vsync just cap the framerate to your monitor refresh rate to remove tearing.. With vsync you still going to see runts and such and probably microstutters if is not write correctly...

capping frames without vsync is a whole different thing... Not confuse this with vsync because its not...
If you think im actually capping frames with just enabling vsync nope is not like that..

For someone who has vowed to never read one of these articles again, you sure do post a lot of worthless comments in the threads. You plan on contributing anything, or just keep on in this vein?

I know you know the difference, but Vsync syncs the framerate to the monitor refresh, it doesn't just cap it. Might want to be specific so it's clear in your post.

Technically it is capped, but yeah you are right..

I dont enable vsync to cap my frames i use different tools for that like dxtory/radeonpro to name a few...
Still suffere from screen tearing but i remove the microstutter without adding the input lag..
