ATI CrossFire - the way it's meant to be played!
 

I was pleasantly surprised to see the major performance boost in Necrovision when enabling ATI CrossFireX.

I enabled maximum settings on 1680X1050 resolution and ran a benchmark with fraps having Sapphrie HD3870 with 512 Mb of GDDR4 - i have got 30 FPS. Then i enabled CFX and have got a WHOPPIN' 57 FPS.

You can't go wrong with CrossFire in this game, it's hilarious to see NVIDIA logo start-up the game..

I'm running HD 4890, runs great, I can't image how much better it will perform when I get a second HD4890 for crossfire^^ The smoother this game runs the more fun it is^^

Yes, it is very important to get SMOOTH rates and while in most games 30 FPS is enough, in NecroVision you should get minimum 60 FPS all the time, and better - constant 100 FPS, because havok physics need high FPS in order for the player to climb those mountains in the game and see LOTS of bodies flying in "ragdolls" all over the map SMOOTH! Turn on fraps, set 1920X1080 with that HD4890 and see how it looks! But seriously - another HD4890 is an overkill...
