Haven't seen this before, so I apologize if it's been discussed already. It's also in the 167.37 drivers, which I haven't seen discussed here yet.

From HardOCP (http://enthusiast.hardocp.com/article.html?art=MTQxMCwxLCxoZW50aHVzaWFzdA==): NVIDIA also now has a new transparency multisampling algorithm in use that it has implanted in its latest drivers. This new algorithm works on every GeForce 8 series video cards and is not restricted to just the GeForce 8800 GT. This new mode is employed by the latest drivers, version 167.37 and the new 169.01. NVIDIA has developed a new transparency multisampling method that has image quality almost similar to transparent supersampling but without the large performance hit. This new mode replaces the previous TRMS with a new TRMS; the option in the driver control panel is still labeled the same however. NVIDIA claims that the new TRMS mode is on average 6% slower than standard 4X AA. This feature will certainly be welcomed as we can enable TRMS and receive better antialiasing on alpha textures compared to the previous algorithm, with less of a performance hit than TRSS takes.

very interesting, i will try it later, currently using supersampling.

Thread title should read 8xxx cards, not just 88xx cards, since it supposedly works for all 8 series cards.

Also, it doesn't seem like it will make any difference for Crysis. From the same article: There is a rather sad issue with the way antialiasing works in Crysis. This comes directly from NVIDIA’s James Wang on the use of Transparency Antialiasing in Crysis: ”Crysis handles foliage very differently from normal engines so TRMS/SS won't work. Bit of a shame really. The game has some built-in foliage AA, but it only kicks in in "Very high" quality mode.” Even if you could enable it, the performance doesn’t seem there yet for it anyway with current video cards.

Actually all cards that support transparency AA will have the new mode. It will replace the old transparency multisampling. So 6, 7 and 8 series cards.

Does it work with 169.01 XP-32 ? I was trying to make it work with Clive Barker's Jericho, but, no success.

The Geforce 8800GT also employs a new type of transparency multisampling. While I havent had the chance to truly investigate it. Its a very nice implementation and will replace the old transparency multisampling. When I get a chance to look do some comparisons I'll be sure to post them up. And until then. Here's a look at Nvidia's PR examples.

The actual reality of the new mode is Nvidia's transparency multisampling looks very close too their supersampling mode and still employs relatively no performance hit. While only the Geforce 8800 GT currently supports it. ALL Nvidia graphic cards that support transparency AA will recieve this update.

.Thanks. I certainly respect ChrisRay's knowledge of nVidia hardware and antialiasing. Although this line I found curious: While only the Geforce 8800 GT currently supports it. ALL Nvidia graphic cards that support transparency AA will recieve this update.Did that occur via the drivers discussed in this thread?

Has anyone else noticed there gpu temps skyrocket with this new driver ??

I was idling around 68 now its like 77c and Crysis was loading around 87c,and
now its hitting 105c at load according to Rivatuner 2.05 !!! :eek2: :bugeyes:

My tempertures seem to have went up about 3 to 4c ,but not really noticeable.

Jumped from 163.71 to 169.04 and temps stayed the same.

I never really saw much difference using Multi over nothing anyway. I think rather than saying "new Multi", they should say "fixed Multi".

Depends on the game. Although in most games, it doesn't make a lot of difference. It's very noticeable in Far Cry using MS TSAA over plain MSAA. It's also slightly noticeable in Oblivion.

His knowledge stems from his relationship with Nvidia(employed). He knows more about current and future Nvidia hardware than most. Of course he'll never divuldge NDA breaking info. ;)

Yep, I'm aware of this.
