4870 performance crysis

crysis is optimized for nvidia cards. if you only like to play crysis then you made mistake to buy xfired 4870's to only play crysis.

Crossfire scaling in Crysis leaves something to be desired, but ATI is supposed to be working on this. Even with the current drivers you should get pretty good framerates as long as you stay away from AA, which doesn't improve the IQ in Crysis much anyway.

k i reinstalled the drivers, and now when i disable crossfire im getting an average of about 30 fps. But with crossfire im still getting about 25 fps. I have the 8.7 driver as well...

lol i guess you have 2 x8800gt's , try seeing it running on 2x4870's in x-fire then , ill post screenies for ya end of the month when i get my second one

ur running that in only high mode , my single 4870 runs it at 38fps average at 1680x1050 + 4xAA at very high , imagine with two of them.

also your in xp with dx9 , dx10 in vista 64 bit is much more demanding.

simple version , ATI RULE ONCE AGIAN

so will my bank balance lol , i need to up my psu as well , current corsair 620w aint man enough , so i gotta invest in a new one , may as well go for the 1000w corsair , hoping the new thermalright t-rad is out too , i dont fancy two of those stock fans running in my machine , there too noisy tbh

on the original poster , going by my experience and similar stuff , you seem to have an issue somewhere , try it with a single card , maybe as said it isnt optimized for x-fire on our cards yet , or maybe that psu isnt man enough so there throttling.

tis on my more info.

currently

DFI LAN party UT x48 mobo
E8400 @3.6ghz
4 gig of ocz reaper (2x2) @ 1066mhz
WD raptor 160 for games
gainward 4870 512mb with asus o/c bios on 815/925
22" samsung 226bw screen

it runs reasonably well at very high with 1680x1050 +4xAA (38fps avg on benchmark) but theres the odd bit in crysis where it drops the framerate a bit too much , so for smoothness when playing i drop it to 2xAA where it seems happier

p.s after seeing alot of comments im starting to think the E8000 series when overclocked is a much better chip for even crysis than Q6000 series chips , seems higher clock speeds are much more important than going from 2 to 4 cores.

Careful mate, you're bordering on heresy with observations like that, don't let facts get in the way of the bandwagon.

lol guys... any help for my problem? Crossfire should definately get better performance than one card. lol wtf is going on

and regarding your problem with CF mike145, do a simple OC on your q9450, no upping the voltage, tell me how that goes... get as close or past 3.2ghz as you can, tell me if your fps goes up... i suspect it should go around ~50

and why're you CF'ing with only 1280x1024 screen? those 4870's deserve to be treated better....

im running at 1280X1024 because my monitors a peice of junk (getting a new one though which will be at least 22" ) Also I dont have a CPU cooler, do you still recommend I try the overclock?

Not really. 40% its quieter than my room fan. I crank it up to 55% for gaming and its noticeable but nowhere near annoying.

aye with the current drivers probably! , but i wont be getting two cards just for crysis lol , im a big fan of Race driver Grid and CoD 4 which will more likely benefit from it. + the next gen of games will no doubt use it. hopefully they'll sort out crysis in a new patch either the game itself or CCC.

i agree on fan noise too , 40% its the loudest item in my machine but bearable , any higher and it competes with the dyson when hoovering!

yep crysis is one of the few games that seems to prefer nvidia , but looking at recent benchmarks the 4870 and 4850 arent slouch's with it , also the ati cards seem to handle AA better , just the sheer proccessing power of the 280 series helps it win overall. but its a minor victory given price and other game's

If you look closely you'll see that Crossfire actually hurts performance at 1280x1024 in Crysis

Heck I get 29.87 average frames in crysis with my system and it's not overclocked at all. Thats with 1 gt....and a q6600....I can't complain and thats with setting on very high except shadows are on medium at 1650x1050...I'm currently debating on getting another card for sli or just getting one 4870

^OCing your CPU won't have much of an impact on avg fps in Crysis. I went from a S939 X2 3800+ @2.5GHz to an E6750 @3.2 GHz and it didn't make much difference in avg fps. Minimums went up in physics heavy situations though, which made me very happy
