A word or two about ATI and adaptive anti aliasing

Recommended Posts

Pardon the long winded post, but I've spent a lot of time tweaking and I have much to share and ask about. I got some textures to show up that were made invisible by adaptive AA.

 

I just started a new game. I have been using enb .199 with mixed results. I do not really see much increase in performance, however it does seem more stable on my HD 7950 using a great many HD texture mods and almost 200 plugins. My textures folder is almost 14 GB.

 

So I'm setting out to squeeze as much FPS as possible. First off I HATE aliasing. It is my number one pet peeve. The conundrum- enb works best with no hardware AA, but the FXAA/SMAA/ENB-based AA/solutions have little effect, especially on foliage or reflective light.

 

But I can live without the top shelf ENB effects.

 

The game's built in FXAA is ok but I use it as a secondary and mostly to soften the look of the game.

 

Multisampling AA is poor unless set to at least 8X. But even then foliage still flickers. For me that equals about 28-40 FPS on average

 

Adaptive AA is great, but you get transparent/invisible textures. Needs to be at least 4X and my FPS is 40-52 outdoors depending on whats around. I notice NPCs really hurt my FPS

 

Supersampling 4X is the look I want, but it cuts my FPS down to 22-32.

 

I went back to adaptive AA and experiemented. For me the first issue I noticed was invisible candles. So I extracted those meshes from the Skyrim-meshes.bsa to my data folder. Now they appear only slightly transparent. Definitely can live with that.

 

 

Still testing things......does anyone have any any ATI-related AA input? Whether to override/enhance, or types used?

4x Supersampling is what I've settled on in the end, I'm not a huge fan of ENB and in the past I've ended up toning it down to the point where it's hardly worth using it, so I don't.

Hey

 

I have the same rig as you and I have been struggling with adaptive AA too.

Have a look here: http://benchmark3d.com/anti-aliasing-iq-performance-comparison-7-types-tested/

4X adaptive seems to be the best quality/performance ratio, but I've also noticed the missing candle textures :(

I don't know how people can be satisfied with FXAA, SMAA or plain MSAA.

And I know that SSAA is far too demanding (especially if you have heavily modded your game and/or played with Ugrid settings)

I tried and tried to tweak the game and CCC settings but with no success. People seem to have give up on fixing this.

Even STEP recommends MSAA or SSAA.

Did you have any luck fiinding a workaround ?

The best luck I had with Adaptive AA is what I reported above....extracting the meshes for the invisible things like candles into the data folder made them visible, although slightly transparent.

 

 

However, using the new .200 ENB tweaked to my system increases performance as it allows Skyrim to use more RAM than 3.1 GB. Thusly I am now able to use SSAA X4 and my FPS never drops below 32. It usually runs 44-48 FPS in the wilderness.
