Question about textures resolution and in-game resolution.

[nomar]

Sorry if it isn't the right section of the forum to ask this but I didn't find a more adequate one.

 

Since some games offers HD resolutions officially and unofficially (skyrim mods or shadow of mordor for example), I was wondering about something, for example, my monitor is only 18.5 inches and it's max resolution is 1366x768, does using like 4k resolutions, that obviously have larger resolution than in-game resolution, will make any graphical difference? Or just placebo?

 

Thanks in advance and sorry for any english mistake.

Higher resolution means a sharper image. Even if your display resolution is lower. This will never be placebo. Just a matter of taste.

However using 4k textures will seriously eat up VRAM so don't even bother with 4k unless you have a minimum of 4GB VRAM on your graphics card.
