just curious why you'd ever want your game to go above 60fps
I have a 240hz montior. Sadly not because my PC is strong enough to support it (unless the games are older) but simply because my old one died and this one was on sale :V My Laptop also has 144hz. Construct games run tied to the monitors refresh rate, so as long as the PC can handle it the game WILL go above 60fps naturally. I'd be quite sad if a game doesn't reach 144hz on my 144hz monitor, especially if it isn't 3D maxed-out eye-candy.
To be fair, my own game also runs at around "only" ~150fps though considering the 2D nature it probably should be more. I just noticed... it does run at 240 in the preview but not in the export. Hmm...
In any case, the faster the game runs the better. If it hits 240fps on your machine it might just hit 60 on an older one. But if it already is chugging along at 60 on yours, the older one might hit 10 fps and it's unplayable.
