"Detecting Windows' framerate"
, by thechange
Measures the time it takes for a vertical blank using multiple readings. Useful for finding out if vertical sync is disabled.
Code
; In case you would require to know the exact time between each vertical blank for whichever reason, ; this is a pretty accurate program which you could use to find out if the person running this program ; has or has not disabled the vertical sync entirely. ; ; The only downside is that it takes a while (seconds) to get at least a somewhat accurate average. ; Naturally, the more time it takes to test -determined by the Cycles constant-, the more accurate the ; final average will be, as one reading is added per cycle. ; ; Another way is using an external DLL and communicating directly with Windows. Graphics 800,600 Print "Waiting..." Delay 1000 Print "Detecting..." Const Cycles = 100 For Count = 1 To Cycles VWait StartTime = MilliSecs () VWait StopTime = MilliSecs () Result# = Result + (StopTime - StartTime) + 0.1 Next Print "Result: " + (Result/Cycles) Print "Detected: " + (Int(1000/Float(Result/Cycles))) + "Hz" WaitKey End ;-->
