4 Gaming with/ without AA

[TootY]

Hi everyone,

 

Just having a general research, searching the big open world for results. As always we find mixed results, so contradicting others and so on.. I recently purchased a 4K monitor and I was interested to know, do you still need to run AA. I've watched a few videos on Youtube regarding 4K and AA 1080p and 4K. 

 

So having 4K, would I need AA, also does AA play a part when you start adding the inches "WINK", going from 27" to 34", would the larger one then require AA as you'd see more real estate?

 

If anyone has any ideas, sources, screenshots, videos etc I'd like to know what the 'ideal' way would/could be.

 

Thanks,

I've got a 290x with a freesync 4k monitor and AA kills frame rates DEAD! Makes most games unplayable but at this resolution my personal opinion is you definitely don't need AA 4k is beautiful and as long as your not a 60fps snob like me and you don't mind gaming at say 40fps as long as the game play is smooth and not a stuttering mess you can set most games at high/ultra settings for example far cry primal and still get very playable frame rates

Generally not, I dont run much AA or any at all even at 1440p as the effects are less noticable

 

higher resolutions generally have less aliasing since the pixels per inch are so much higher meaning jagged lines are less noticable

Generally on a 27-34" 4k screen no AA is needed 

 

on larger screens you will start to need it again as the pixel density decreases

OK, so at a smaller resolution you should be good. If for example you had a 46" 4K, could you start to add lower amounts of AA instead of having to go for the highest AA settings.As it's still 4K you are only trying to smooth out the extras? If that makes sense?

I played about with this the other night, I went from x2 AA to x8 AA and x2 did lower my frame rate to sub 30fps which isn't great when its off I get 40-60fps depending on the scene but at x8 it went to like 2-3 fps so no way can my rig handle 8AA @ 4k I don't even think a 1080 could do that?

its nothing to do with it being 4k, its to do with the pixel density

Example, 24" 1080p screen is 97 PPI  AA is needed

 

27" 4k screen is 163 ppi - AA not needed

 

46" 4k screen is 95 ppi, even less than a 24" 1080p screen, MORE AA needed

 

(1080p at 46" is 48 ppi, which is crappy, hence why you have to sit super far back)

So yeah low ppi = more aliasing needed and further sitting distance
