Re: Why not display frame time data in a familiar format?

Ned, I do believe the OP and a few others are not saying they want bigger numbers. They just want the term brought back somehow, even if it is d(FPS)/dt (flip, you need to brush up on your calculus ;)). Unfortunately for game testing, you can't cut infinitely small where t -> 0. All we have are ind...

He still thinks I'm somehow discussing the merits of FPS second-based polling. I don't know why.

Re: Why not display frame time data in a familiar format?

Therefore, frame time is a supplemental testing to FPS which is still king for measuring performance. Zarking fardwarks, have you not grokked the last two pages? Your single-minded need to convert any GFX evaluation into an FPS number is simply maddening and ignores all of the data that Damage &...

Re: Why not display frame time data in a familiar format?

I'm stepping into serious speculative land here, but the way that I've seen it works something like this: FPS = Performance Frame time testing in ms = level of stutter level of stutter =/= absolute performance Therefore, frame time is a supplemental testing to FPS which is still king for measuring p...

Re: Why not display frame time data in a familiar format?

No worries. This stuff has been under attack from fanboys and closed minded enthusiasts alike since the day it was first talked about. That 7950 vs 660Ti review definitely made things a bit more heated too. It's natural to go into defensive mode about it, as that's exactly what I've been doing for m...

Re: Why not display frame time data in a familiar format?

You're only referring to the line chart. Frame time testing can be used to measure a huge array of things from percentile latency, to smoothness, to focusing on outliers and where things can go wrong. This is exactly what min/max/avg is trying to capture, but fails to do so accurately. *edit* To use...

Re: Why not display frame time data in a familiar format?

Frame time is basically the minimum frame rate. What matters is the amount of time spent at that minimum, which is harder to quantify in terms of FPS. If we go by averages then the good frames tend to smother out the bad frames, making it a bit hard to represent as a simple graph. HardOCP's style o...

Re: Why not display frame time data in a familiar format?

To me the real advancement was measuring down to a point you can't take any more samples, not what units the data is shown in. In the past people had graphs showing averages down to the second at best but nothing that really gets to the individual frame velocities. This. So much this. Agreed 100% G...

I'm simply talking about presentation of the findings in a format that is easier to digest. That doesn't change the data gathered, tested, and displayed. It is simply changing the information to help reiterate that this is a replacement for the standard FPS metrics that have been in place for years...

Re: Why not display frame time data in a familiar format?

So far, that hasn't panned out too well. I'd say an overwhelming majority of folks that I talk to about this view it as a way to capture something else entirely which isn't quite as important as FPS.

I feel like you guys are trying to tell me what the difference is between FPS based tests and frame time based tests. I don't have any confusion on this.

Re: Why not display frame time data in a familiar format?

Ugh. Despite your trashing of my comments you still want an FPS number to fall back on. FPS died the instant Scott posted the first frame latency article. Get used to it. The metrics are going to change and FPS will no longer be one of those metrics. The noobs will actually have to learn something....

Re: Why not display frame time data in a familiar format?

You didn't address anything I said above though. In fact, you wrote most of it off with a fairly snarky retort that betrays lack of comprehension. The problem is that your solution, i.e. converting 99th percentile frame time to FPS, deliberately obfuscates the original measurement just so that some...

No, I'm not wedded to it in any way. I'm talking about the clear difficulty in getting people to understand what any of it means. Yeah, it's clearly written, but there's a very visible block that people are having in understanding that this is a more accurate measure of performance rather than an al...

Re: Why not display frame time data in a familiar format?

The problem is, fps is by definition an average over a period of time . But the individual frame times are basically a number "at an instant" (loosely). IMO it is even more confusing? You're absolutely right, but I think that people who understand it know what you mean. The people who don...

Why not display frame time data in a familiar format?

Here's what I propose. Use all the same tools and methods to find the data. Now, when it comes time to present the data, simply convert the numbers into familiar FPS numbers. Lets say a 99th Percentile Frame Time was 17.54. Just display that as 57 FPS. Call it "99th Percentile Frame Rate"....

Re: Tools used to determine the frame timing

Yeah, that's how I've done it, so far. We've recently built an import tool that just does that calculation during the import of all five runs worth of data. Once you have the deltas, you don't need the timestamps anymore. Any chance of you sharing this wonderful tool? I've been running some benchma...

Re: Tools used to determine the frame timing

I used FRAPS. It dumps out a log when you hit F11 to benchmark and that includes the exact time each frame was rendered. Plop it into a spreadsheet and subtract each time from the previous time to get numbers you can put into a graph , or just sort if you're looking for frames over a certain thresh...
