Stuttering when playing with Recursion

Hi everyone,
I have a problem with the Recursion Stat Tracker. Every time I want to use it my game starts to stutter whenever there are more than 2 guys on my screen. I tried different settings, but the stuttering won't go away. I play on High Settings and have constant 60fps, even when running Recursion (it just feels like 10-20 with Recursion because of the stuttering). As soon as I exit Recursion the stuttering is gone. I hope someone can help me. If you need additional information just ask for it. Thanks!
My OS: Windows 7 Ultimate 64-bit (6.1, Build 7601) Service Pack 1 (7601.win7sp1_gdr.150525-0603)
Recursion Version: 0.10.3.2

Are you playing in Windowed or full screen mode? Try full screen. Make sure the tracker is minimized / hidden when the game starts.
