The fact that you see no difference between single gpu frame times and multi gpu frame times, doesn't mean that it is a reliable way to measure them when testing multi gpu systems. Don't get me wrong it probably is, but with single pgu it has been validated by comparing frame times from Fraps with frame times from build in benchmarks that produce frame times as well.

I believe the following article compares Fraps with several games: http://alienbabeltech.com/main/?p=33060&page=3

So with all this buzz talk of frame times on the net recently I figured I would jump on the boat and build a tool for WSGF to churn out graphs quickly.

I had been disccussing and previewing this in the wsgf irc channel, however haldi requested I show a preview here. :)
Still a bit of work to do yet, but proof of concept is working...

Intention is to allow upload of csv via web broswer and get a graph in return, along with a batch process mode so we can dump files to an ftp folder for processing in a single job lot that can be used for our wsgf benchmarks.

Will update when ive something more to show.

EDIT:
Iv'e added a front end with options and upload...

Made updates to http://delphium.mine.nu/grapher.html

Features:-
Offset - set starting possition from begining of file.
Chunksize - how many data points to use, starting from the offset value.
Label Interval - set the frequency of y-axis (frames) labels.
Graph size width/height - graph image size in pixels.
GPU - which gpu was used in the test, also first half of main title.
Game - the game used, should be auto detected and is also second half of main title.
Max range - set a limit to the max y-axis (milliseconds) range staring from 0.


Example output...

i did 'a few' benchmarks on VRAM usage....

Quote:
Hitman Absolution Benchmark:

Ultra Quality: 8xMSAA
1920*1080: 36-108 43 FPS 3200mb
3840*2160: GPU Limit 0 FPS
______________________________________

5760*3240: 9-18 14FPS 4020mb
7680*4320: 0.4-11 7FPS 5617mb
7999*4499: 0.3-11 6.5FPS 5780mb
---------------------------------------
Ultra Quality: 0xMSAA Overclocked: (1425mhz VRAM +1150mhz core)
7680*4320: 0.08-12 6.6FPS 5580mb
----------------------------------------
Ultra Quality: 0xMSAA Overclocked: (1850mhz VRAM +1150mhz core)
7680*4320: 0.4-13 8.5FPS 5580mb
7999*4499: 0.4-15 8.5FPS 5780mb
______________________________________________________________________
Lowest Quality: 8xMSAA
1920*1080: 56-81 62FPS 1800mb
3840*2160: 0.4-33 18FPS 5450mb
3974*2235: 0.05-31 16FPS 5880mb
4031*2267: 0.1-30 15.7FPS 5880mb
4070*2289: 0.6-15 5FPS 5911mb
4128*2322: --------- 5660mb (Definitiv VRAM Limit... 8sek pro bild!)
4479*2519: --------- 5635mb (Definitiv VRAM Limit... 8sek pro bild!)
-----------------------------------------------------------------------
Lowest Quality: 8xMSAA Overclocked (1850mhz VRAM)
4070*2289: 01-15 13FPS 5807mb
-----------------------------------------------------------------------
Lowest Quality: 8xMSAA Overclocked: (1850mhz VRAM +1150mhz core)
1920*1080: 50-88 68FPS 1850mb
3840*2160: 0.4-40 21FPS 5450mb
4070*2289: 0.1-37 18FPS 5911mb



Verry interesting is the part 4070*2289 Pixel in Lowest Quality with 8xMSAA The Benchmark runs at 5 FPS! But the VRAM is completly overloaded.
Image

When you overclock the VRAM from 1425mhz to 1850mhz you get 13FPS and a way smoother Graph!
Image

(the low graph before the spike is the Loading screen!)

Sadly that only helps for VRAM limit and not for all Microstutter :cry:

some more toughts about Microstuttering: nice read.
http://techreport.com/blog/24415/as-the ... e-and-more

Rage3D s new Benchmarkinf strategy!
http://www.rage3d.com/reviews/video/his ... ex.php?p=3


And PCPer says why Fraps sucks for Microstutter definition.
http://www.pcper.com/reviews/Graphics-C ... /Frame-Rat

be aware that the Graphs you see in this post are not the raw data but the Filtered Frametimes which ignore 1 pixe high Frames which would be counted as whole Frame.

I have read those articles as well. This one from HarwareCanucks is also a good read: http://www.hardwarecanucks.com/forum/ha ... sfire.html.

It seems to me that more and more sites are considering using frame times instead of fps as a measure of performance, which is great :onethumb:
