The Future of Anti-Aliasing Settings in Question: NVIDIA Discussion

Final Words
Driver AA settings are getting too complicated and unpredictable. It would be terrific if all game developers could support AA settings in-game or through the driver, but that just isn't a reality. Moving forward, as programmable techniques mature standard MSAA may prove more and more difficult to force on across the board through a driver. For NVIDIA, the complications of maintaining driver controlled CSAA and MSAA are numerous. The impact on the end user is that AA may or may not function in the expected way, causing headaches for the gamer, hardware maker and software designer.
From our perspective, the informational approach through a warning when AA settings are changed is great, but could be subject to the Windows user "just click OK" mentality. Educating the average gamer on the possibilities is something we can get behind, but we just aren't sure that this approach would work. Even so, we wouldn't mind seeing this implemented, especially if we have an option to avoid seeing the pop-up once its been shown once.
Profiles don't seem like the right fit, as it can be cumbersome to manage settings for each game on a computer both in the game and in the driver. Perhaps if profiles gain in popularity this could be the way to go, but we feel there is a better solution.
Implementing a coolbits-like feature to enable override AA in general driver settings seems like the best way to go. This could even be combined with the warning box idea without a problem. This would both encourage the use of in-game settings through the removal of the driver option from the default install and provide the possibility of educating users who discover how to enable the option.
In addition to providing feedback on what NVIDIA should do, we are interested in the way our readers currently tackle AA. In testing, we use in-game settings exclusively when available. What method do you use to set AA?
As we mentioned, NVIDIA has not decided that any of these actions are necessary at this point. This article is meant to open a discussion on the best possible way to proceed, and your feedback is important. If we all have the goal of maximizing customizability and accessibility without causing problems for the majority of users, we will be in a very good place indeed.

Reading the article it occurred to me that basically what Nvidia are trying to achieve is to simplify the process for the und user.I thought that you could have an ordered list of driver features that would be progressively turned off based upon a target FPS rating. As for most people, when all is said and done they want a reasonable FPS with as much eye candy as is possible.
It would basically function as a dynamic fallback system. Similar to the way that modern CPU's adjust their settings based upon load only here we are talking about rendering features rather than speed.
It would be possible to have a basic and advanced version.
The Basic version might look like:
1> MipMap Detail Level
2> Anisotropic Filtering
3> Anti-Aliasing *Possibly with: (Method 'a'/'b')
4> Vertical Sync
While an Advanced version would be like:
1> MipMap Low
2> MipMap Medium
3> Anisotropic Filtering 2X
4> MipMap High
5> Anisotropic Filtering 4X
6> Anti-Aliasing 2X Method 'a'
7> Anisotropic Filtering 8X
6> Anti-Aliasing 2X Method 'b'
8> .....
- For both Basic and Advanced the user is able to change the order of the items in the list to keep the features they deem most iportant.
- In the Basic version the driver would automatically fallback through the levels of a feature. e.g. for Anti-Aliasing: 4x('a') -> 4x('b') -> 2x('a') -> 2x('b')
- In the Advanced settings the user is specifying the order of each individual setting so no fallback is required.
The ability to log events would enable users to analyse their results and better tailor their settings.
As far as notifications go, I guess you could have a tick box on each row as to whether a notification will appear for a status change on that feature.
I'm not sure how well this would work as a system with current API's, maybe with DX10 where there are no more API's (correct?) it would be better, as some of the changes are not high speed dynamic changes and seem to require a restart of the video system.
With some changes to programming I'm sure it could be achieved.

Coolbits + the normal display properties is all you need.Hopefully Nvidia will let those of us who hate their new display properties manager use the old one...

Why not initialize a profile dialog box when a program tries to go to use DirectX/OpenGL? You could use checkboxes for every time, first time, etc. located in driver settings- probably first time as a default. I hate opening the Nvidia profiles, but it if automatically popped up, and integrated the warning boxes/list of programs known not to function with MSAA (better if integrated directly into a profile) then I would love it. Manually wading through the profiles as-is stinks, therefore I do not use them AT ALL. If you wanted to experiment with performance by tweaking profiles you could set the checkbox to open the profile every time a program tried to go to use DirectX/OpenGL and play with the settings each time, until you found what you wanted, then "lock" the profile with a checkbox or whatnot that would cause it not to re-open automatically. Also... please don't force me to use the bloated interface that came about in the 90/100 series of drivers. I like the old control panel, and being able to see my GPU temp without having to load Ntune (which is incompatible with my PC- causes bluescreens constantly).DasFox - Monday, March 26, 2007 - link
I don't see why this seems so complicated.I personally leave all Nvidia driver settings on default, and I use nHancer to enable game profiles, and when AnandTech said;
"Profiles don't seem like the right fit"
I guess they haven't used nHancer, because life in gaming with it, can't get any easier.

I think I speak for a lot of users in that I am not wanting the popup box solution mentioned in the article, many people are so incredibly tired of popup messages. This is not a fault of nVidia, there are other companies that have worn out the popup box already.neofit26 - Tuesday, March 20, 2007 - link
I am usually changing the AA setting from the driver's panel, since very few games have them in the interface. Now with nHancer it's even easier. I wish NVidia copied that interface into their drivers.And, unlike a previous poster said, nowadays more and more games do not allow AA to be used and even forced in the driver's panel. I am talking about Gothic 3, Vanguard, Silent Hunter 4 and Stalker apparently. And they don't give anything in exchange. Why would I choose a "David Thompson erotic photography" blurry bloom-like effect in a combat game, instead of non-jaggy lines?
Anyway, for me the choice is simple: if forums say that the game has no AA and it cannot be forced through the driver panel - I don't buy it.

Obviously one of the concerns here is maintaining good support for older games: "...driver AA settings are a necessity for enabling the functionality on older games or current games..."Currently the 4:3 scaling option for widescreen monitors is broken for the Geforce 8 on WinXP. In the Nvidia control panel the option is called "Change flat panel scaling", and it simply doesn't work. Here's a forum post of others with the problem: http://forums.nvidia.com/lofiversion/index.php?t23...">http://forums.nvidia.com/lofiversion/index.php?t23...
What is more important for image quality in games: AA settings, or not stretching 4:3 images to 16:10? Clearly the latter. Fix the basics first.
Additionally, the Nvidia's nTune program is also broken, since it forgets your settings every time you reboot.

The latest 100+ series beta drivers fix 1:1 scaling along with a host of other problems in XP. They're beta, but a helluva lot better than the 2 month+ old 97.92 WHQL. Pretty sure 100.65 WHQL fixed 1:1 in Vista, but not totally sure since I haven't made the move yet.AnnonymousCoward - Monday, March 19, 2007 - link
Oh, one other thing. You said 100-series drivers fixed 1:1 scaling in XP. Do they have 100-series for XP? http://www.nzone.com/object/nzone_downloads_rel70b...">http://www.nzone.com/object/nzone_downloads_rel70b...AnnonymousCoward - Monday, March 19, 2007 - link
Oh really, 100.65 fixes the scaling? Poster "thredge" on my link said "Was hoping the 100.65 newest driver I just got would solve it, but was again dissapointed." I haven't tried it since I assumed he was right.
