Ogryn's Rumbler grenade causes frametime hiccups

Every time a grenade shot from the Rumbler explodes, a frametime hiccup accompanies it. I can’t tell if it’s the graphic, or the sound effect, but something about the explosion of that weapon is causing a significant enough change to hike frametime.

Doesn’t matter where the explosion is, distance wise, relative to you.

I have the same issue. Also occurs with trauma staff shots and barrels. Most explosions actually. But rumbler, as of like patch 10, is the worst offender and very consistent.
