I had a strange situation where I had 0 problems coming out of Act 2 and into Act 3; All of a sudden, I started getting ping spikes and the network problem icon that actually caused serious stutters and lag spikes (even if the ping doesn't go up).

I attributed this problem to Valorant/Rito because I didn't have this problem and I've been using the same router/Wi-Fi since Act 1, but after nearly quitting from the stuttering/lag, I tried plugging in an Ethernet cable and my gameplay has been spiffy clean since and everything is as crisp (or better) as it's ever been in the last two acts.

Not saying Rito doesn't have issues, but if you're not using Ethernet, it could potentially be on the client-side's internet connection. My hit-reg has never felt off ever since I've switched.

just for your reference, I live in western Canada with a pretty fast internet connection (150Mb/s), so it's definitely not the speed but rather the consistency caused by my Wi-Fi.
