High res = no bluring,
better preformance then AA???
Your opinions please. :)

You can't make comparision on this becouse its all depends on game in some games you will get massive slowdowns on higher res but decent performan on lower rez with 4xAA , but then again on other games AA gives big performance hits , and high res does not :rolleyes:

Jaggies are much more noticable in some games than others, as is the AA blurring. I think BF1942 is the most difficult to make a choice on. Texture shimmering is really bad in places and AA helps. The jaggies are really noticable around the edges of planes or ships. The Midway map in particular really looks better with AA enabled. On the other hand the font of BF1942 is really goofy and the HUD text is very difficult to read with AA switched on. Some textures like the grass on the island look so much sharper with AA off. Turning AA off after you are used to it is like being short-sighted and putting on a pair of glasses for the first time.

Hmm I'm playing BF1942 on 1600x1200 res and didnt notice any bigger preformance improvement then playing with AA hell I think it even runs faster then with 4xaa and 2xaniso.

You do realize that 1600x1200 is the equivalent of 800x600 with 4X AA and 2X Aniso, right? So doing that at the standard 1024x768 *isn't* fair, it got better jaggies quality than 1600x1200 and pretty much identical texture quality.

my taste fluxuate but right now i like high res and 4x af. most my system can handle really smooth.

as a gf3 ti 200 owner I have found that using high res rather than lower with AA is the best option for performance.

AF doesn't just sharpen textures with AA. Its primary purpose is to fix the perspective of them, regardless of whether AA is on or off.

1600x1200 did have the same performance as 800x600 in 4X on an old card like the GF2 that just did plain super-sampling. I think with today's cards the AA modes run faster. Then there are odd modes like Quincunx that try to offer better AA at much faster speeds.

Running in 800x600 with AA does have one sure advantage, you can run your monitor at a higher refresh than you can 1600x1200. But depending on your monitor, that may not matter to you.

I try to get my games to run at 1024x768 with some kind of FSAA and aniso (if performance isn't too great). For older games like UT and Q3A, my system plays 1024 with 4x AA and 8x aniso perfectly, always over 60 fps in UT and over 80 in Q3A.

For more demanding games like UT2003 and poorly coded ones like HFS: Hot Pursuit 2 I have to drop to Quincux. Whatever blur there is doesn't bother me at all. And with these games, using aniso basically isn't an option.

Plus at 1024, my refresh rate is 100 Hz which helps keep my eyes happy for extended gaming sessions.

I run at 1280x1024 with 2xAA on ... i really don't see a difference between 2xAA and 4xAA, and I don't really notice much with aniso on ... i'm usually too busy running around to stop and stare at the floors and walls and get shot ...

with cards like the r9700Pro we increasingly do not need to even make such decisions. just crank the res and turn on both AF and FSAA and get great peformance :POKE:

I should post some shots up showing more aliasing and texture shimmering at 1600x1200 than 800x600 with 4xAA and 2xAF.
Too damn lazy though. :condom:

Anyway, if someone can post up 2 shots that will be cool. :condom:
