4890 crossfire pwns BF3 @ 2560x1440

well i just upgraded from a normal 1920x1080 monitor to a hazro h27wc which has a resolution of 2560x1440.I was amazed at how much better BF3 looked at this res.

When i purchased the monitor i thought that i would have to upgrade my graphics card to be able to run BF3 at such a high res with everything turned up max.

Im using 2 x powercolor pcs+ hd4890 (the fastest factory overclocked 4890 available) please bear in mind that these are the most powerfull DX10.1 cards available.

just finished benchmarking BF3 with everything at Ultra, with no AA (not required at this res i honestly cant tell the difference with it on or off) and Motion blur off (hate it)

Fraps results @ 2560x1440 everything ultra, no aa and no motion blur tested on full 64 player sharqi FOV 80

Frames 68716

Time (ms) 1076033

Min 20 fps

Max 146 fps

Avg 63.860 fps

Turns out i have lost about 20 fps compared to running at the same settings @ 1920x1080 and im very pleased with the way my cards are still performing.

Using ati 11.11 drivers these seem to be the best for my setup game runs perfect with no stutter

dont care much for dx11 dont think the difference between dx10.1 and dx11 warrants the outlay of big money, still plenty of life left in the good old 4890 crossfire.

to get that sort of performance with a dx11 card or cards would cost a lot

im sure most people here know that the 4890 is a dx10.1 card

.

It's hardly pwning BF3 is it? First off, 20 fps mine, second no DX11.

doesnt drop to 20 fps during gameplay the 20 fps figure is when you first spawn, during gameplay lowest i have seen it drop to is 35 fps and its very smooth

bf3 uses very little tesselation and that makes it very difficult to tell the difference between dx10 and dx11

be my guest but do it at 2560x1440 with it all cranked up with no aa and lets see what you get

I had loads of problems with my 4890 crossfire
seems that ATI stopped supporting them when the 5870 series came out.
and the drivers gradually got worse.

good to see your setup doing well at higher resolutions.

i think ATI make the drivers worse on purpose to force people to upgrade

just benched wake island all cranked up no aa and no motion blur 2560x1440

min 45,
max 155,
avg 81.53

I literally don't understand how my 4890 only manages 30 fps on all low settings at 1680x1050...

I'll try your driver settings because this seems uncanny.

big fps drop and a little stutter with the latest drivers try 11.11c instead and try it on ultra at a higher res if possible
