Would a 2GB frame buffer be helpful for 3D vision

The experience I explained above, (3'rd post I believe) in the lesser rig with a GT240 and lower settings, the performance hit from 3DV to no 3DV was present but not extreme, from what I had been reading I didnt anything would be playable but was pleasantly surprised, with the i7 , GTX 460 SLI setup very high settings/1080p the performance hit is near 50% or greater.

So... drop your settings to what they were before and your performance hit with your new hardware will be even less?

If you run a gt240 and max out your settings, games will be unplayable. Turn on 3d vision, and it will remain unplayable.

Running a gt240 with low settings in games can mean that the CPU becomes the bottleneck (especially if you've dropped the settings more than you needed to). Now turn on 3d vision in that situation, and the extra overhead you didn't know you had gets eaten up, but doesn't massively drop the performance. Because you still had gpu power left over.

Modern games at high resolution and high settings use more GPU than CPU power. That's why overclocking from 4 ghz on an i7 to 4.4 ghz on that same i7 doesn't give you a bunch of extra frames per second in most games.

Vram has nothing to do with anything in this situation. It just holds the high res (or low res!) textures for everything else to access. The faster the card, the faster your framerate. A fast 512 meg GTS 250 will destroy a slow 1 gig GTS 220 - yes, even in 3d.

[quote name='Iceman0124' post='1128055' date='Oct 8 2010, 09:45 AM']I have a 120HZ display and NV shutter glasses kit (love it), I was planning on 2X1GB GTX 460's, however it just occured to me the 2GB cards might have an edge is 3D vision, anyone know for sure? Or know where I can find out? Been looking snd asking all morning and no luck yet.

Video RAM is for holding textures. 3D Vision needs high frame rates. Raw power is the key. So invest your money in 1Gb GTX 460's x 2 for SLI and you should be good.

At the present time I'm running a GTX 470 its vinalla and it runs all my games at max settings (pretty much ) at 1080p. There are some issues with the Lost Planet 2 Benchmark. That took me down to about 20 FPS in 3D.

So I'm going for two GTX 460's 768Mb. I'm not worried about Video Memery at all. That is still 1536Mb of VRAM.

Are you familiar with the phrase "Benifit Curve"? Basically the more RAM you add to a system, at some piont the rate of benifit tappers to a platoe.
