Benchmark to measure "mininum" FPS during a demo?

[JF_Aidan_Pryde]

Is there a benchmark avaliable which measures the minimum frame rate during a demo? This is obviously more useful than a average FPS number as it's the standard deviation which measures smoothness and consistency. There are claims that some cards stay within 30-40FPS range while others spike all over the place, if this can be confirmed, then it is indeed a worthy finding.

Perhaps someone can write a program to do this.

SeriousSam you have the min and max numbers during benchmarking. If you didn't know by the way.

Didn't Tom's hardware post framerate graphs some time ago ? Seemed like a good idea, depending on the overhead on the data collection of course.

FRAPS (www.fraps.com) can do what you want (though only on a per second base).

That's the thing I like most about UT. Ideally all games should allow a benchmark mode, which should return minimum, average, and maximum framerates that occur during the execution of the benchmark. I have used this in UT to optimize my overall settings to avoid having my framerate drop below my monitor's refresh rate setting (75Hz). This way, I am able to enable vsync, getting rid of tearing, and I don't experience stutters except in the case that some other system component is responsible (hard drive caching and squat, which can be addressed in other ways). It makes for the smoothest game I've experienced yet.

The ideal benchmark would produce a series of numbers which are the time taken to render each frame.

Then you can plug it into excel and get all the figures you want, upper quartile, variance and allsorts.
