Well lag on Stadia is almost non-existent, so.....Genuinely curious, how in the hell do you play Thumper with any kind of input lag?
That said, the Stadia version is overly generous on late button-presses specifically.
Thing is, it doesn't actually need to be as generous as it is, and a number of players have noticed it.
The first time I tried Thumper, I kept messing up because I was too early, thinking I needed to account for lag. I didn't.
I'm currently on level 9 and man that game is intense as all heck!
(BTW, founder here. Rough launch for sure, but now it's my preferred way to play. No downloads, no noisy PC or console in the background, just pick a game and play. So far I've finished Metro Exodus and Gylt, and I'm well into Borderlands 3. Thumper I've already talked about. I only have a 68mbps connection and it's been great)
