Ok, thanks.

Been waiting for a while and haven't seen a mod approve any runs. Is this game still active with mods?

Its PC not PS3.

I have used Livesplit, but that is sometimes inaccurate and needs to be adjusted (Human reflexes). Also you have to manually press it to start and end, which can interrupt a run, especially if you are doing multiple attempts.

I have used Youtube Frame Timer, https://slashinfty.github.io/yt-frame-timer/

and I have used WatchFrameByFrame, http://www.watchframebyframe.com/

but both give different times. Also do video game settings matter at all, I mean could it affect the frame rate in the game?

Any advice would be appreciated.

WatchFrameByFrame.com, 60FPS

Starting Frame: http://www.watchframebyframe.com/watch/yt/jKpa213VIbo/0.6600000000000001

Ending Frame: http://www.watchframebyframe.com/watch/yt/jKpa213VIbo/4.939999999999938

4.94 - 0.66 = 4.28

Total: 4 seconds 280 milliseconds
