What kind of FPS running 3D

[luckydemon]

I'm planning on doing 3D for roughly 25-50% of my gaming and I'm wondering what kind of FPS I can expect with certain cards while running 3D.

From the benchmarks I have found, they are all based on running games in standard 2D mode. Based on the number I have found I'm curious what FPS I can expect and if anyone has any educated guesses to what I'd see. The benchmarks I have are for 2 games I regularly play currently.


PLEASE REMEMBER ALL FPS ARE BASED ON 2D. I WOULD LIKE TO KNOW WHAT I CAN EXPECT FOR 3D GAMEPLAY.

GTX 460 (768MB)
L4D - 1680 x 1050 - 107 FPS
L4D - 1920 x 1200 - 102 FPS
BC2 - 1680 x 1050 - 79 FPS
BC2 - 1920 x 1200 - 42 FPS

GTX 460 (1GB)
L4D - 1680 x 1050 - 110 FPS
L4D - 1920 x 1200 - 103 FPS
BC2 - 1680 x 1050 - 83 FPS
BC2 - 1920 x 1200 - 45 FPS

GTX 465
L4D - 1680 x 1050 - 118 FPS
L4D - 1920 x 1200 - 96 FPS
BC2 - 1680 x 1050 - 86 FPS
BC2 - 1920 x 1200 - 43 FPS

GTX 470
L4D - 1680 x 1050 - 131 FPS
L4D - 1920 x 1200 - 114 FPS
BC2 - 1680 x 1050 - 102 FPS
BC2 - 1920 x 1200 - 55 FPS


So based on these FPS numbers is standard 2D mode, what can I expect for 3D FPS? 20% less? 30% less? 50% less? More?

If I had to guess (and trying to dig through my brain about the old benchmarks I remember seeing about 3D vision scaling), you'll see a 45-60% decrease in performance when running 3D vision. Of course it depends on the game you're playing, whether you're applying high anti-aliasing, and how well 3D is optimized for each game. Remember that in 3D, the card is rendering twice as much, so it's logical that it'll take twice the performance.

You can take a look at this article to help you get a better understanding of what to expect, even if the article is a bit dated:

It was right at 50% for me on most games running the 3D vision discover (the red/blue) which makes sense because it's having to render everything twice from a different perspective. So halve all those numbers. Still playable in everything but 1920x1200 probably on all of them.

You have an SLI build, a single 460/470/480?
With 3D on a large resolution, you should have 2 460's SLI'd to get good performance.

Alot of games don't look right in 3d unless you turn shadows off and reduce other settings so you don't need the absolute cream of the crop to run 3d on a single display at 1080p or less, but it sure helps.

The monitor I'm looking at, the samsung 2233RZ, maxes at 1680 x 1050 so that's the max resolution I need and I'm not going to be running the highest AA and other optional settings. Detail and overall quality will be high but I dont need AA, etc.

I'm contemplating Dual 460's but not if one 470 would suffice. But you guys are the experts so I need your thoughts!

I have a single 465 overclocked and I play Transformers war for cybertron, crysis warhead, UT3, GRID and some older games in 3d at Nvidia's recommended settings (sometimes it tells you to turn off shadows or reduce detail) with no problems at 1080p, so a single 470 should be fine for you for now at your resolution.
