[PCPer] Frame Rating Comparison - HD 7950 CrossFire vs GTX 660 Ti SLI (full review) - Page 4  

post #31 of 542
Can someone tell me what all this "frame rating" is all about? What is it used for? I have seen a few threads pop up about frame rating but I haven't bothered to read them. Is this only for sli and crossfire?

The only thing that bothers me about the "observed" framerates that this testing gives us is that if we're not really seeing ANY more frames with CF (see: http://www.pcper.com/image/view/21524?return=node%2F56812), wouldn't users have complained that there is no difference?
I mean, I can easily tell when my FPS drops to 50 FPS or less, so wouldn't it be super obvious that you are getting 40 FPS instead of 80? I would think there'd be far more unsatisfied CF users if this was the case. Or can this be blamed on some bias? That the brain just decides that since that little number in the corner of the screen doubled, the image is more fluid?

There's obviously some benefit to the runt frames, if nothing else the game engine is stepping at the higher frame rate even if the picture isn't making it to the screen, and like you said, people would notice if there was no benefit at all. So the question then becomes, how much of an impact are the runt frames - and the only way to find that out is probably going to be to wait until a driver fix eliminates them and then see what the performance difference is. Maybe it'll be the same, maybe it'll knock 20% off the frame rates - who knows.

I think this is the most compelling screenshot - you can clearly see in the game image (on the shop doors) where there are two tear lines from the runt frame - so that frame isn't conveying much information to the player, even if the game engine sees it as a full frame.

It's subjective, but the difference definitely doesn't apply to everyone, not everyone notices stuttering.

Whelp....there goes my upgrade plans!

Was going to get a 7970, then later Xfire, but not with these issues. Won't bother with Nvidia, since it only has 2 gigs of VRAM, which will not be long, till games max that out.

Only one I really notice any problems in for those videos, is FarCry 3... Well, besides all the screen tearing on them all.

Its funny that some folks still saying the opposite. Doesn't it so obvious that xfire has more stuttering? At 50% slower, you guys still can't detect it?

The sli obviously smoother in both FC3 and SD but has some stuttering in BF3. Come on folks!

That's a nice piece of ignorance right there that didn't contribute at all other than flammable material.

Neutral is a valid position as well you know. Besides, buying an AMD gpu doesn't make a person an AMD fanboy.
Look at the GPU in my sig (hint : 7950) now read my opinion : BF3 was similar, FC3 was horrible for the AMD side, SD showed a little more stuttering on the AMD side.

See ? No fanboyism.

Either you're accidentally mistaken, or trying to spread false info to the uniformed. Surprising behavior from somebody with 4,000+ posts

i will apologize here as i have in this thread (post # 413) . . .

Same with me. Now I kind of regret going 7970 in hopes of trifire. But then again, what else offers the same value - since I got the card for 330 Newegg a while back. And some games really do use more than 2.5k vram I discovered.
