Has anyone else noticed a large drop in FPS when using the ice sword or bow when you can first purchase them? When I hit the merchant I lose around 40-50 FPS, but it goes back up when I put it down and look elsewhere. I've tried rebooting (of course), adjusting the resolution/super sampling, lowering the framerate cap, disabling all monitoring (fpsvr and the native steamvr performance graph), motion smoothing is off, I have no motherboard monitoring/controlling software (like msi afterburner, etc), and I've disabled mobo RGB in my BIOS. Other games work fine, and this game has worked fine otherwise (not the best frame rate but loads better than what I'm seeing now).
