[mascaras]

Vantage tests @ Crossfire Added

great thread. i heard GRID didn't scale well with CrossFire. did you rename the .exe or force AFR through CCC? or did it just scale well out of the box?

i just run the game

CCC = Default


btw: GRID Race with the Patch released few days ago >>> http://files.filefront.com/Race+Driv.../fileinfo.html

Soooo....
HD4850X2 =~ 9800GX2 ||
9800GX2=2x 8800GT (G92) || ==> HD4850=8800GT (G92)

Nice... kinda late, but still nice

[Metroid]

Mascaras is that possible to place the results on a table?

I think your great efforts are really well appreciated, however misunderstood by some forum members by the fact is not clearly organized. Keep the good work up

According to GRID help file (or readme file), the game is not optimized for any dual card config. I think I read this.

However when I play it with my 8800GT SLI, both cards are pushing, the temps on both cards are identical.

I suppose the same thing happens with two cards in CF.

The official driver for RV770 looks like to be 8.7, cause in 8.6 there is nothing said about these cards .

Nice scores
Can you compare a 4850CF (~440$?) vs. 8800GTS 512 SLi (~340-400$)?

I am very impressed with this review and thank you for doing it.

I am confused on one thing in your charts there are red text with an Asterisk

I can't find any foot note to explain what this means. I know dumb but confused.

[diablos]

Very nice review, mascaras!

Could you, please, tell us if there is any micro stuttering when running in Crossfire mode? I know you already told us earlier that in Crysis there are some lock-ups, but what i refer to is this.

Cheers!

@mascaras

beside Crysis , all games i tested i didn't noticed much mico-stutering ! (at leat not too noticeble)

great thread. i heard GRID didn't scale well with CrossFire. did you rename the .exe or force AFR through CCC? or did it just scale well out of the box?

you´re right , i started testing single card today , and guess what???

1920x1200 AA x2 ultra settings = almost same Fps as CF (70/95)

so i guess the game dont scale well @ Multi GPU (same hapens with GX2 and SLi) , however the good new is that single hd4850 can run the game @ 1920x and AA with very good FPS


im uploading the SS



edit: added Race Grid @ single card

added COD4 singleplayer @ single card


added 3dmark vantage Performance test @ Single card

[mascaras]

Did you notice any gain? can you post a comparision?

the first part of review was hd4850 Crossfire with CAT 8.5 , the only single card test i done @ 1st part of review was the crysis but i also tested today with Cat 8.6 and same thing (also in CF no gains)


i only started 2nd part review today @ testing single card in Games but already with cat 8.6 ( i didnt test singl card in games with cat 8.5 before, so i cant compare )
