[PCper] Frame Rating Dissected: Full Details on Capture-based Graphics Performance Testing - Page 17

post #161 of 420
I think we're missing the point here, it doesn't matter that there are small frames, if every frame was that small, the experience would be excellent. What matters is that we have a mixture of 20 pixel frames and 500+ pixel frames. Look at it in terms of frame interval, if you spend 30ms displaying every other frame, but 0.3ms on the rest, it's going to look damn near identical to an output with a constant 30ms frame interval. A fix would allow that same hardware to display every frame for 16 ms.

So im watching a couple of youtube videos on this guy...
http://www.youtube.com/watch?v=lY0iFojEKRU

It is me or i notice something weird here?
Image quality is not even the same... seriously?


Then he add to the description a link to his frametime article???

How you want people to believe this guy when hes not even comparing apples to apples.....

The SLi part is noticeably smoother but lighting is quite different-I haven't played sleeping dogs,is the nvidia part really with graphic settings toned down? It also occurs only outside (indoors seems similar), Could it be that there are less light sources on the left side? Check the part just before he starts to descent, there is a canteen at approx 1:05. Night and day really.

the indoor part looked basically identical, is there anything like clouds that would change lighting between takes?

Far Cry 3 soft shadows at the beginning...
Crysis 3 LoD/DoF as well look when is going down the rope look at the middle red square and tree behind it..


Ok im done with this guy lol

I hope you understand that FRAPs measuring before the rendering pipeline is a huge flaw in testing - Before the GPU driver does anything? How can you even BEGIN to consider such a test to be valid? Testing and benchmarking is the easy part. Most reviewers aren't software developers, however, and they will never understand what goes on behind the scenes at the API level. Again - benchmarking is easy.

Now before you further continue in defense mode, this isn't personal. I like your site very much and I read it quite often. I find your reviews to be excellent and well written. That said, you owe your readers valid testing methodology, to simply brush off these concerns is a major mistake on your part. Again. PRE-RENDER PIPELINE data is a very real concern to which both AMD and nvidia agree.

I do look forward to your followup articles that you mentioned smile.gif Again, nothing personal. I however have to say that the issues with FRAPS are very real and should be taken seriously. Pre-render data is not a valid testing methodology, and it is my belief that you shouldn't be so quick to brush such concerns away.

Perhaps, FCAT will be a better methodology than FRAPs. Although that is developed by nvidia, so i'm not sure how well that will go over with the community. Surely there will be some debates about that.

If this was the case then why would there be any discrepancy between different cards in the testing? The video card must be doing something if the graphs are completely different yet the only change was the card itself...

The videos are slightly out of sync which makes your screenshots hard to compare, but the lighting is certainly different between the two - not the first time there have been lighting difference between the companies, but I don't know what ipact that owuld have on the latency. It's a dynamic game so there are always giong to be differences - hopefully they'd use the same save game to begin both runs, but if they start inside and then run outside I don't know what that does to the traffic etc, which is always going to make these kind of comparisons difficult.

Oh really? And the soft shadows on far cry 3? and the LoD on Crysis 3? How you explain those?>
textures as well on sleeping dogs.,..

Haven't watched those yet. If the settings are the same but the output is different then that is definitely something they need to address with AMD and Nvidia. Still wouldn't be the first time there were visual differences with the same settings though. And I'm still not sure what impact that would have on the frame latency (FPS maybe/yes, but I don't know about latency). The other sites got similar results, did they post screenshots/videos? Be nice to see if it affects all of the sites.
