Need help with timers.

I've started taking racing more seriously and I just wanna ask for help setting up either WSplit or llanfair.

I have the global hotkeys set for both but when I'm runnning path of exile I cant seem to get the global hotkeys to work. I have it set on F5 but when I F5 in game splits dont happen. When I'm alt tabbed it works though. Please help :3

Wsplit is a speedrun timer thing, not sure how to use it.

That said, you don't really need elaborate tools like that to compete in races, especially since it's real, real easy for your timing to get messed up by random stuff.

maybe f5 is bound in game. Or maybe fullscreen application prevents global wsplit hotkey to register. Try google this.
