BC2 crossfire eyefinity is broken. You get great fps but it feels laggy unless you go back to 1 card or just 1 monitor. There are a few threads here and more on widescreengamingforum with this same problem. Dont make the same mistake I did and blow 400$ on a second card, 150$ on a bigger power...
@ stock voltage around 940-960 on both my XFX 5870's, I cant touch the memory, even 1210 causes problems. If I max out @ 1.350 then I can get around 1070mhz but the fan needs to be around 80-90% to keep it below 85c
^ just did some testing.
In crossfire or single card with single monitor, vsync gave BC2 mouse feel a nasty "lag" feeling Ive felt in most games when vsync is turned on. I like my mouse at 2000dpi and 75% in windows, twitchy if you will, and vsync is always a no for me.
If i maxed out the...
I cant seem to find a clear answer, if I pick up this board can I use my two 5870's in Ati crossfire (not hydra) @ x16/x16 pcix? or would it be x8/x8 like my current MSI gd65?
Thanks guys!
^ nice! Its good to finally see someone else having the same problem with crossfire eyefinity and bc2 feeling crappy unless you have 120+ fps.
I almost made the trip to frys to pick up a x58 board and i9 for the two x16 lanes, lot of money to throw around on a possible fix tho :(
^ p55 both slots running at x8 2.0 according to gpuz.
I have 1 5870 pushing my 3x1080 and I have to have everything on low to get the 90-120 fps I like out of a single card, and thats OC'd to 1050mhz. With 2 cards I can get double the fps almost exactly, just feels slower and more "stutter"
I picked up a second 5870 for crossfire only to be bummed by micro stutter.
XFX double lifetime warranty along with box and everything included. Card is perfect and looks brand new.
^ dang it I was almost about to go find my second bridge.
Makes me feel better I'm not the only one turning off crossfire because of this. Some games don't seem bad, dirt2 seems fine and smooth.
x2. Picked up a second 5870 (off craigslist so no return :mad:) in the hopes of turning up BC2 on my 3x1080p eyefinity setup. Sure I get double the framerate but it feels super laggy and even at 100fps doesn't feel as smooth as a single card at 60, I have to be pushing 120fps to get that same...
