That’s in the game by default, it’s always been there as far as I’m aware. A very strange stylistic choice.

Well yeah there isn’t an issue here that’s just how it works, you can’t fit 60 frames per second into 90 refreshes evenly, therefore some frames will persist for a shorter time to fit into the refresh rate.

30fps is just fine, it’s your attitude that is not good

Through a ton of testing I have never encountered a single benefit, logic would imply that it should have no benefit due to the way it inflates the swap file whilst simultaneously reducing the system’s use of it.

Theoretically the only potential benefit might have been hugepages being enabled, but this is now enabled by default in SteamOS 3.5 which is why a lot of people are now reporting no/reduced benefit.
