570s SLI Running Bioshock infinite - Page 2

VRAM allocation is interesting.

BioShock Infinite VGA Graphics Benchmark performance test

Graphics memory usage

Before we move onwards into the conclusion it is handy to know how much graphics memory the game requires in a preferred resolution. You'll notice that 2GB graphics card are sufficient and that's the number this game has been aiming on. A graphics card with 2 GB of graphics memory minimum is really recommended by us. Should you have less available and run into performance issues, the easiest way out preventing frames from being swapped back and forth in that frame buffer is to select lower quality settings or disable AA levels.

Above you can see a wide variety of in-game selectable quality modes @ 2560x1600. We switch in-between the image quality modes (Low to Ultra) to monitor frame buffer utilization. As you can see we are hovering at the 1.5 GB of graphics memory with FXAA enabled starting at High quality mode settings already. Once you increase the quality settings towards Ultra mode you start to reach a turning point where the game almost hits 2 GB of graphics memory. The measurement shown above is fairly similar and applicable for 1920x1080/1200 and 2560x1600. Now not everywhere in the game that much graphics memory is used, but there are some critical points in-game where you will reach or even pass the 2GB in combination with the highest quality modes. If you'd apply an exclusive AA mode like MSAA though graphics card drivers, we have no doubt you'll breach the 2GB threshold. So be careful with that.

Overall the advise is simple enough, make sure you have a graphics card with 2 GB of graphics memory when using High to Ultra image quality modes. Please keep in mind though that memory utilization will vary a bit per level, it's not a very precise thing to measure. As such take these values as an indication, not a precise measurement.

Anyway, 2GB minimum for your graphics card, it is the magic number to find Elizabeth wink.gif

Thinking these cards would at least last me another year. From a horsepower perspective they are fine.

Just turn off SLI. I did.

I had issues with 470's in SLI, Now I play with a mix of ultra/very high at 2880x1800 with AA enabled.

managing a very playable framerate.

I rather run it through nVidia Inspector before I turn off 1/2 my juice..

To OP, try turning down the settings a bit, especially AA.

good idea, AA is a nVidia killer sometimes.

infinite uses post AA methods (FXAA 3.0 i think) its actual impact on performance is minimal to none. if you on win 7 disable desktop themes before you launch the game also if running multiple monitors disable one; doing this frees up about 250mb of vram

Malmental already posted about the vram requirements in this game. I just bought a 570 for SLI myself just yesterday. Disappointed it will not serve as well as I had hoped for newer games with high VRAM requirements frown.gif

I don't own Infinite but a lot of people were commenting on how Tomb Raider was running. I ran through that game (no tressfx) at 1440 and, to me, I thought it looked fantastic. I think you Really need to be picky about how your games look before 570 sli disappoints you.
