If the framerate is equally matching the refresh rate then that shouldn’t really change anything since the timing should be identical in either. The higher refresh rate will really only help decrease latency if you’re giving it enough frames to pick up on them faster. It’s always nice to have better incremental options for framerates though. Like having the steam menus be 80FPS but the game 40, that’s pretty awesome! So I’d say it’s worth it for simple conveniences like that.
midwest US here, it seems like everybody is still in packaged status. Guess next week? Given the 3-5 days we should all have it by thursday latest. In a perfect world of course. I’m personally super busy this week so I don’t mind waiting. Excited for the better screen!
