GeForce 9900 GTX & GTS Slated For July Launch

[cptkoulis]

has anyone observed microstutering on vista 64 with 4+ gigs of ram?
i have the feeling its a ram/os issue rather than an inherent flaw of crossfire/sli

i've been using 2x9800GX2 + E8500@4+GHz on Vista 64(4x1GB DDR3) and i was hoping i'd be able to play Crysis @1920x1200(since 2560x1600 is still a slideshow)

The framerate was decent,i think it was around 40fps(according to Fraps) BUT the game was not playable at all.The in-game delay was about 300-500ms when an explosion or gunshot occured,just like lagging in a multiplayer game.As you can understand,this effect cancels the extra power of the second card,it actually delivered "on screen" worst result than a single card.

I am not sure if this is called "microstuttering",i had to read/learn about it while trying to tune my system.Correct me if i'm wrong

So,i guess the GTX280SLI will perform much better compared to 9800GX2 SLI because of better synchronization
