I just built this PC:

q9450 at 2.66ghz (havent oc yet)

4gb pc2 6400 ram at 800 mhz

2 x hd4870 in crossfire (fans set to 45% idleing at about 45-50 degrees)

gigabyte x48 motherboard

antec 900

pc power and cooling xfire rdy 750 watt psu

And im wondering if these results are proper for crysis. Id give you an actual benchmarking test... but whenever i run the benchmarking tool it never actually completes the test for some reason. It loads a level and shows me the FPS stats etc. but doesnt show me the test results (avg fps) at the end. Im probably doing it wrong... but anyways.

Im getting about 25 fps avg on very high settings at 1280 X 1024 resolution. Also I dont believe the problem is crossfire because when i disabled crossfire i got lower results.

whats the problem??

Make sure you install the latest 8.7 catalyst drivers. They improved performance in crossfire for a lot of games.
Even I get more FPS with my rig at 1680x1050. What are your AA/AF settings? Try turning off all AA and AF, and see what happens.

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 :p

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.

I agree. I have a Q6600 @ 3Ghz, 4870 @ 790/1000, 4 gig DDR2 800 and I can seem to only get it playable on the same settings at 1280x768 res

[:mousemonkey:7] Careful mate, you're bordering on heresy with observations like that, don't let facts get in the way of the bandwagon.

the mobo helps too ,theres soo many tweaks u can do to increase performance on it , ive spent ages reading clunk.org.uk regarding my board still got loads of stuff to learn though. x48 boards certianly work well with the 4870's though.

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....

i used one 4850 on my crappy old motherboard and i played on very high with 30+ fps@1440x900...

i was overclocking to 650/1050 but still your 4870 should handle that game no problem.

could your motherboard be bottlenecking them? if they aren't pci-e2.0 at dual x16 you may have issues...

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!

seems way to low. my 2 gtx 260 oc 714/1230 im able to play at 1680x1050 dx10, very high, 8aa getting 20-35ps avg about 25-27fps which is playable to me.
well ati cards dont run crysis well thats wat i heard.
