Anti Aliasing in Great Battles

[SCG_ErwinP]

Hey guys!!

 

I read a topic in this forum about disabling AA in game settings and enable it in GPU driver and I did it but I have a couple of questions:

 

Firstly, which is the in game Anti-Aliasing Method (Super-Sampling Anti-Aliasing (SSAA), Multi-Sample Anti-Aliasing (MSAA), Fast Approximate Anti-Aliasing (FXAA), Other) and worth override it?

 

Secondly, which could be the settings to better graphics visual in my PC?

• In AMD Radeon Software Adrenalin I setting up such as following:
  • Anti-Aliasing Mode: Override application settings
    • Setted at 8xQE
  • Anti-Aliasing Method: I changed from Multisampling to SuperSampling
  • Anisotropic Filtering Mode: I setted at 16x

 

I'm satisfact how game runs smooth right now but if I can achieve better results, why not?

Later I will take a screenshot of Radeon Adrenalin software settings.

This is my settings at moment.

One thing of note is that overriding the settings don't always work.

 

The default anti-aliasing in the game menu should be Multi-Sampling or MSAA that goes up to 4X. If Overidding in Radeon software works correctly, setting it to 8x instead of 4x should show a minor improvement.

 

The type of Multisampling that looks best is probably down to personal preference, I honestly do not remember the different between the different algorithms, they probably all give fairly similar results with a slight difference. In any case, what Multi-Sampling does is use a special equation to figure out what it thinks a pixels nearest neighbor should be, 8x means 8 sample points. 2x only 2 sample points.. The high the sample points the more accurate it typically looks.

 

Supersampling on the other hand is completely different. It is the best form of Anti-Aliasing but also the most taxing. What it actually does is shoots the whole picture at a higher resolution and then downsamples it to your monitors resolution. so 2X is twice the size of your screen res and 4x is 4 times the size.. I believe. As an example, if you have a 1920x1080p monitor, running 2x Supersampling should render the game at 4K resolution and then it will blend and average out every single pixel on the screen with its neighbor when it downsamples.. At least I think it is rendering at 4k, I might not have that correct..  Anyways, rendering at 4k to run a crispy version of 1080p.. It's not a very efficient way of doing things, but if you have the extra horsepower and frames to run it, might as well go for it.

 

One thing you can try on the Display tab of the Radeon settings is turn on "Virtual Super Resolution". It only works on resolutions that are not incredibly high to begin with, like 1080p.. On a 4k screen or something like that it will be grayed out. What that does is basically does the Super Sampling but it just bypasses it being a specific anti-aliasing option and will just scale up and then shrink everything on your screen, GUI, text overlays and all.. It might be worth giving that a shot and comparing your performance to supersampling.

I think you need 4x SS to equal 4K which is 4x the number of pixels 3840x2160

if your graphics card can handle that then just get a 4K monitor or TV. The cost of running SS isn’t really worth the benefit as you’re still looking at 1080p.

A real 4K image is much sharper and 4K TVs are so incredibly cheap these days there’s not much use in super sampling.

Only issue with most 4k TV's is the input lag and latency.. Though I know some of the better onnes are getting pretty close to monitor specs.

 

If 4x Super Sampling is equal to 4K, then what would 2x be? I suppose it's easy to look up. I figured 2x would mean 2 pixels rendered for every 1 pixel of what the display is, which would be 3840 x 2160, also known as 4K. You are doubling the horizontaland the vertical resolution.

 

Maybe  that's not right and  2x could be something like 1.5 pixels down-sampled to 1 pixel? That doesn't divide into 1 correctly but maybe it looks OK. I know a lot of games have what I think they call "oversampling" and you can set it to an array of percentages, over and under 100% (native resolution) to give a sharper image, so it's possible that weird numbers and percentages look OK with super sampling.

 

But I mostly agree.. If you spend a grand on the fanciest video card and are running a 1080p monitor that has a basic refresh rate, you are wasting your money and know amount of Super Sampling will make up in image quality for what you spent on the card.
