ATI drivers in XP.. 3870 cards..

[trog100]

i have just been thru my later games trying crossfire.. with most of them it quite simply dosnt work anywhere near properly.. i am wondering why.. he he..

it works nicely in an older game like fear.. it works nicely in all the 3dmarks.. it works in crysis.. but bugger all else..

dirt.. it makes it unplayable compared to just one card.. not just dosnt show a gain.. it wrecks the game and halves the frame rates....

word in conflict.. it drops the frame rates by 40% and causes major stutters..

witcher.. again a drop in frame rates and major stutters..

conflict denied opps.. it drops the frame rate by 30%..

supreme commander it crashes..

serious sam.. an older game.. it works but dosnt show any gain..

i have tried the cat 8.3 drivers.. they are worse than the 8.2s.. a lot worse..

i am useing XP.. one card works nicely two cards work with some things but mess up other things.. not one of my later games except crysis runs in crossfire..

reviews i read tend to say C/F works in vista dx 10.. most of them dont use XP any more.. i am a bit puzzled.. it does seem a driver game problem.. but for me C/F is pretty well useless with all my current games..

i wonder if ATI have given up with their XP drivers..???

Wow man, that sucks. I've got a x38 board now, and I hope this isn't going to be a widespread issue.

the cat 8.3's fix all that mainly but it is only for vista, if you use 8.3 in xp it ruins everything.

thats why i am wondering if ATI have stopped optimizing their XP drivers for later games..

fear has been around for ages so has the 3dmarks.. C/F quite clearly works with them.. they seem to have made some attempt to get C/F working in dx9 crysis.. but the rest just seem not to work in C/F dx9 XP..

one card plays the games okay and i can disable C/F.. but it does make me wonder what would happened if i had have bought a 3870 x 2 card where C/F cant be disabled.. would none of my games work properly.. :wtf:

8.3 in XP ruins everything?

Odd, I have no issues, in fact they perform better than 8.2...maybe it's because I use XP x64 (which is basically server 2k3)?

8.3 works fine for me, except for getting a CCC error on reboot, and Control center will not open. The drivers seem to be fine though.

so it works fine for some..???

can we have some examples of what it works fine in.. ????

i have just tried the 8.4s.. the same splotchy blocks of colours in the crysis gpu bench as in the 8.3s.. the 8.2s dont do it..

all very odd.. all i can say is it dosnt work find for me with XP crossfire.. and i will quote exactly what it dosnt work fine with..

i have tried it with lots of current games.. i am trying to find out whats wrong..

i am using win XP 32 bit dx9.. the system works perfectly except for the crossfire game problems.. the fact it works perfectly in some things but not others suggest to me a driver problem.. the fact the 8.2s work better than the later cats also strongly suggest a driver problem..

ati have admitted the 3dmark scores got dropped with the 8.3s and claimed to have fixed this with 8.4s.. however they instantly crashed my 2005 battle of proxicon test.. some improvement.. he he

trog

ps.. just to add.. this is purely a crossfire problem for me.. one card works perfectly.. two cards dont in most later games.. they degrade performance big time compared to one card..

Have you tried the 8.4's yet?

[trog100]

Have you tried the 8.4's yet?

yes.. the same same massive colour artifacts in crysis as the 8.3s and 3dmark 2005 crashed as soon as i tried to run it..

everything after the 8.2s seems downhill.. i am now back to using the 8.2s with crossfire disabled..

fear and the 3dmarks all show a nice performance boost with the 8.2s in crossfire.. every single one of my other later games show a positive degrade.. crossfire is unusable in some and simply gives lower frame rates in others..

in short a total waste of space except for banging out better 3dmark scores and a small gain in crysis providing i stick with the 8.2 cats..

i am a wee bit baffled.. more so because the 3dmarks and fear show crossfire gains but nothing else does.. he he

what bothers me is the loss of performance with crossfire.. i didnt expect much of a gain with some later games but seeing worse performance with two cards than with one has me wondering..

when i get mine up and running i will help out hopefully this isn't a huge issue as i will have a very similar system running...

[trog100]

this is an example of what i am getting.. the world in conflict in-game bench.. ..

with just one card.. crossfire disabled.. 8.2 cats..

two cards.. crossfire enabled.. 8.2 cats..

http://www.cavecom.com/pics/cfwic.jpg

a noticable drop in performance with two cards and some jerkyness.. the game plays sweet as a nut with just the one card.. crossfire disabled..

the biggest drop seems in the "lows".. 28 down to 17..

we are having basically the same problems that whoever started the thread is having. we have 2 hd3870 video cards. no game in xp wants to load with crossfire except call of duty 4. that seems to be the only game we can play with crossfire enabled. how can we get our other games playing with crossfire enabled?

You can always try the age old trick of renaming the .exe for each game.
There are, what ATI calls, Crossfire profiles for certain games. I'll try to post the list of names that are known to work, but basically Oblivion, Fear, quake4 and CODMP work well for DX9 games. I'm at a loss to remember the names that work for OpenGL apps.

surely the idea of a profile is to make the game go better.. and if a game has to be four bloody years old before it works something is way wrong..

dx9 has to work.. dx10 is still in unplayable frame rate land for most things..

a list of ancient games that are known to work with C/F is taking the piss.. he he he

ps.. i just tried renaming the world in conflict executable from wic.exe to fear.exe.. a positive difference.. the massive texture flickering disappeared (good) but the result showed a drop in the average frame rates from 47 to 40 (bad).. he he

disabling the cat ai gives the same results with two cards as with one.. basically the second card dosnt fire up.. some kind of profiling is gong on it seems..

8.4 i have no problems with
