That's because 4xSSAA is rendering at 4 times your screen resolution and entirely impracticable. Same thing as the Witcher 2's ubersampling


Just use msaa x4

MSAA isn't available on Metro LL. It's just strange how a 700$ card can't max it lol

You can force it through the driver. Just add a new profile under under Gaming->Application settings.

What's the main difference between the two? I was playing crysis 3 with my overclocked settings with ssaa x2 completely fine then switched over to msaa x8 and my driver crashed.

Is msaa more stressful on the GPU whereas ssaa is moreover CPU dependent?

Ssaa stands for super-sample anti-aliasing. The image is rendered x times the resolution. For instance, 4x SSAA means the image is rendered 4 times the resolution, and then scaled down. MSAA stands for multi-sample anti-aliasing (iircc). The technical stuff behind it is a little more confusing and harder to explain, so I'll just leave this here
http://en.m.wikipedia.org/wiki/Multisample_anti-aliasing
Ssaa is by far the most taxing aa out there, but yields the best results, and thus you won't have to go much higher than 2x, whereas msaa often is unsatifying at 4x, making 8x the only option.

Hmm, strange. It seems msaa x4 was more taxing than ssaa x2.

Comparing apples for apples, ofc. 2x vs 2x, 4x vs 4x etc thumb.gif
It also depends a little on the arch, but there's not a massive difference.
