Nowadays on any reasonably performant system, it would just possibly pop the start menu up for a second, and then you'd click on the game -- everything should be fine outside of super competitive situations. Hitting start was always a rare event anyway, but now it's been degraded from a rare catastrophe to a rare minuscule inconvenience.
I would guess the opposite? 4k monitors are fairly cheap while GFX cards which can run games at that resolution with a decent FPS are expensive. Maybe hardware has gotten cheaper or way more performant in the last years though.
But if you remember back in the VGA days, it wasn't uncommon to have a game set an 800x600 resolution even though you had a 1024x768 display, so switching in and out of the game came with some delay to manage that.
Famous last words of many a unemployed junior developer...just sayin'.
Specific arguments aren’t the same as no arguments. The distinction is important here.
