Calling the Most Discriminating Eyes

[UaVaj]

for those of you that have eyes of cyborg.

have an anti aliasing question.

in the crt days. 0.25 dot pitch (now called pixel pitch per inch) was the gold standard.

fast forward today. a 28" 4k display offers 0.161 ppi.

compare to a standard 23" 1k display offering 0.265 ppi.
obviously the 23" needs some AA. (imho - at least 4x msaa)


----------


by going from 0.265 ppi down to 0.161 ppi.
how much AA can one reduce with without giving up any quality?

who has done a side by side comparison?

Completely dependent on the game.

Yup. For fast paced FPSs (like Tribes Ascend CTF 2012/13), I was usually moving too fast to care whether there were jaggies on the side of a building. I was focused on shooting the enemy or not getting shot myself. It was not unusual to hit 300+ KPH on cap runs or chasing cappers.

The only time I noticed the scenery was when playing HOF or sniping - and still there wasn't much time for that on an active server.

you referring to the quality of the texture.

so for the comparison. use the latest triple AAA game such as Crysis3 or BF4 who's textures are superb.

Still tough to say. Everyone's different and has different levels of tolerance.

Also, PPI and dot pitch are not the same thing.

Is this a math question? Because I'll bust out the calculator. I just want to clarify if you want subjective opinion, or if you are looking for translating dot pitch to equivalent anti-aliasing stuff.

So I'm thinking you'll just calculate the size of a jaggy based on pixel size, then convert that over to the reduction of jaggy size according to anti-aliasing level, and somehow scale them to correspond to each other? I think it's doable.

I can tell a difference between 4x and 8x, but I'd have to be actively looking for it. 4x is usually what I use, but 2x is an enormous improvement over none.

 

[UaVaj]

correct - PPI and DPI are different measuring tools for different technology. brought up DP to help transition folks who did not understand PPI.

at the end of the day. both is a measurement of how far red to red is.

with that said.
how about
23" 4k display offers 0.132 ppi.
vs
23" 4k display offers 0.265 ppi


will take both the objective math answer (preferably) and the subjective iffy answer (for comparison).

x2. same sentiment here.

this is at 0.265 ppi.
