If the current leaks are to be believed the goal is for gta6 to run at stable 30 fps. The commenter above is saying that in order to hit 60fps you would need to reduce the graphics settings.

There will always be a circlejerk about resolution and fps but the consensus is a 60 fps floor There are exceptions to be made about classical animation frame rates as they were made to be played at a locked rate.

I personally find that ever since ray tracing came out the graphical bloat has gotten out of hand. Developers need to focus more on optimization and we need to stop making excuses.
