Hitscan weapons

Hello again! I created a simple ray system in Construct 2, but the problem is that, even at short ranges (2048 pixels), it uses a good 16%-ish of my CPU. I know this value is approximate, but I still feel a bit 'ehhhhh' about the whole thing. Is there anyway I can improve the performance at all, or am I forever doomed?

For me, running the debugger with node-webkit, at the start of the layout CPU spikes to about 7 - 10% for around 15 seconds before dropping. Then after that during normal gameplay just sitting still shooting the ray it's at 1% or lower. When moving around and shooting it goes up to 1.5 - 2%.
