[Various] Nvidia GeForce GTX Titan Reviews - Page 198  

post #1971 of 3575
Here is the way I understand frame times. If you think I'm wrong, don't just tell me I'm wrong. Tell me WHY I am wrong.

Frame time percentiles don't seem to translate well in regards to a user's actual experience.

Perceivable stutter happens when you have a sizable gap between one frame to the next. 20-25ms can be noticed by some people. I found Skyrim very hard to play on 12.11 beta because of stuttering. When I did frametime testing, there were a lot of frames 20-25ms apart which I could easily notice.



Yep, that sure was a mess. And it played like it. Then AMD got on the ball with 13.2 and fixed it 95%.



But notice I said 95%. From time to time there are still stutters as evidenced by those spikes. And no, it's not the game because my 670 ftw didn't do it.



Looking at this graph, the 690 hits a 20ms gap several times. In fact, the graph looks very similar to my Skyrim 13.2 graph which also gives me a bit of stutter here and there.

The Titan sees no such gap or even close to such a gap.



Yet when measuresing frame time percentiles, you'd get the opposite impression not reflected in real world gameplay.

That's my take. I believe in actual gameplay, the Titan would provide the better experience. However, 690 is by far the best dual gpu setup for reducing stutter.

This is a great post and needs to be understood. This is why I hate the way frame latencies are presented. We need them but we need to make consumers more aware of what kind of data they are looking at.

Nvidia still has the 15 SMX unit part it can release and price drop the Titan if the 8970 competes... It likely won't though as all it'll be is two 7870s.

Hello. SLI GTX Titan, 3770k 3.5 GHz, 1920x1080p. How many fps in Crysis 3? 70fps?

xoleras - those charts that you have posted a million times are pointless...

It's a valid discussion. No matter how you would like to trick people into thinking otherwise, most frame latency benchmarks are showing the GTX 690 to be superior than the Titan. Apparently, this makes you angry and upset. Everyone else was having a meaningful conversation because it's a valid question: why are the results showing what they are?

When you have a weak argument or can't explain results, resort to name calling and insults?

I think your argument is the weak one, and i'm not sure why your still trying so hard to tell us the TItan isn't worth it. Your are proving to us you don't understand what causes the stuttering. The difference here is, on the games you keep linking both frame latencies are low enough that you won't notice them on either system. It's the games the other people link that show how annoying it is to get games with microstutter. Generally speaking, when a new game comes out you have to wait for SLI optimizations too.

You also have to realize those charts are not very good because they don't show a time-based graph. A steady frame delay of ~20ms is better than a frame delay shooting back and frorth from 10ms to 40ms. The 690 can average lower frame delays, but still have more noticeable "stutter" because of this.

A graph like this:
900x900px-LL-5f472978_7970vsyncon2.png

Versus a graph like this:
900x900px-LL-5f79c96f_13.2vsyncon.jpeg

If you average the delays out, the top chart can actually sometimes seem better... but that is definitely not the case.

that's two things I never liked about the gtx690. besides that, it's a great dual gpu card. best ever really.
