2xSSAA vs 4xMSAA

Recommended Posts

Which one is better? I know SSAA is harder on the GPU vs MSAA. But I'm not sure between these 2.

To be honest I can't really see much of a difference between these 2. I'm running on a 55" 4K TV.

On my system 2x ssaa is much better, but hard on performance especially in vr with dynamic lights.

2xSSAA is harder on performance than 4xMSAA?

The minimum setting that I can use on my PC @ 1920x1080 resolution on a 24" monitor is 4xSSAA. Both 2xSSAA and 4xMSAA (or anything MSAA for that matter) are nowhere near as good as 4xSSAA. However, I would say that 2xSSAA is better than 4xMSAA, and that it is probably slightly harder on performance.

I run 8xMSAA with Nvidia's MFAA enabled (not even sure if MFAA has an effect on P3D) at 1440p, does a pretty decent job and definitely doesn't hit the GPU as hard as SSAA. Seems like with X-Plane's Vulkan, DX12 also made a noticeable improvement on anti-aliasing for me, so the shimmering and jaggies aren't as bad as they used to be.

8xMSAA would be comparable to 4xSSAA?

Nah, SSAA is still better.

Is the difference noticeable also on 4k monitors? I understood SSAA is not really required on those?

MFAA. interesting. I really have a hard time to get my graphics crispy.. That is the only thing I miss from FSX, there it was at least all a bit mroe anti aliased.

Found my system could run 2xSSAA but VC instruments were slightly blurred. After trial and error went for 4xMSAA in P3D with Nvidia inspector Antialiasing transparency Supersampling set to 4x Sparse grid supersampling to compliment. Also in NV inspector set Antialiasing Mode to compatibility.

Best of both worlds. Clearer VC instruments and very little outside texture ‘flickering’.

It depends on the screen size (dpi)
