Had regular frame drops/stutters with a 1080Ti (see clips, below). Happened about 2-4 times every match. As you can see, it only lasted a split second, but it was still very distracting. This only happened in Rocket League; no issues in other games.

Recently upgraded to a 2080Ti NVLink SLI setup, and now Rocket League is buttery smooth. Haven't experienced even one hiccup with it in well over a month. Everything else in my PC stayed the same.

But, the question is: why? Obviously, Rocket League isn't so GPU intensive that it needed the added power (it only pushed the 1080Ti to ~50%). I'm hesitant to write it off as a defective GPU, too, because I didn't have any other problems with that card and I have several friends who suffered, and still suffer, similar issues.

Could this be a Pascal issue that isn't present with the new, Turing GPUs? Does it have something to do with the SLI configuration (I have the second GPU set to do PhysX calculations, exclusively, now, if that might matter)? Any other thoughts?

Thanks!
