Same here for RocketLeague.
Since the last major vorpX update (21.1.0) I get random massive fps drops.
The stuttering happens in intervals of about 3-10s, last for 0.5-3s and feel like fps drop to 5 or so.
The game did run perfectly smooth before the update.
more debugging info:
The vorpX framerate counter shows a solid 90fps/90fps for game and headset all the time, ie. before, during and after the stuttering.
The RocketLeague in-game performance graphs show no peaks whatsoever.
I changed every configuration I could find in vorpX, in-game and NVIDIA panel (incl. custom resolutions) but nothing seemd to make the problem better or worse.
I usually use the TechnoGoat vorpX profile as a basis, but also tried the vorpX default profile.
RocketLeague itself updated a couple of days before vorpX and started Season 2 on exactly the same date as the vorpX update.
